-**Flexible log monitoring with real-time streaming over HTTP/SSE and TCP**
+# LogWisp
 
-LogWisp watches log files and streams updates to connected clients in real-time using a pipeline architecture: **sources → filters → sinks**. Perfect for monitoring multiple applications, filtering noise, and routing logs to multiple destinations.
+A high-performance, pipeline-based log transport and processing system built in Go. LogWisp provides flexible log collection, filtering, formatting, and distribution with enterprise-grade security and reliability features.
 
-## 🚀 Quick Start
+## Features
 
-```bash
+### Core Capabilities
-# Install
+- **Pipeline Architecture**: Independent processing pipelines with source(s) → filter → format → sink(s) flow
-git clone https://github.com/lixenwraith/logwisp.git
+- **Multiple Input Sources**: Directory monitoring, stdin, HTTP, TCP
-cd logwisp
+- **Flexible Output Sinks**: Console, file, HTTP SSE, TCP streaming, HTTP/TCP forwarding
-make install
+- **Real-time Processing**: Sub-millisecond latency with configurable buffering
+- **Hot Configuration Reload**: Update pipelines without service restart
 
-# Run with defaults (monitors *.log in current directory)
+### Data Processing
-logwisp
+- **Pattern-based Filtering**: Chainable include/exclude filters with regex support
+- **Multiple Formatters**: Raw, JSON, and template-based text formatting
+- **Rate Limiting**: Pipeline rate control
+
+### Security & Reliability

 # Architecture Overview
 
-LogWisp implements a flexible pipeline architecture for real-time log processing and streaming.
+LogWisp implements a pipeline-based architecture for flexible log processing and distribution.
 
-## Core Architecture
+## Core Concepts
+
+### Pipeline Model
+
+Each pipeline operates independently with a source → filter → format → sink flow. Multiple pipelines can run concurrently within a single LogWisp instance, each processing different log streams with unique configurations.

+- **Level**: Log level (DEBUG, INFO, WARN, ERROR)
+- **Source**: Origin identifier
+- **Message**: Log content
+- **Fields**: Additional metadata (JSON)

+# Authentication
+
+LogWisp supports multiple authentication methods for securing network connections.
+
+## Authentication Methods
+
+### Overview
+
+| Method | HTTP Source | HTTP Sink | HTTP Client | TCP Source | TCP Client | TCP Sink |
+|--------|------------|-----------|-------------|------------|------------|----------|
+| None | ✓ | ✓ | ✓ | ✓ | ✓ | ✓ |
+| Basic | ✓ (TLS req) | ✓ (TLS req) | ✓ (TLS req) | ✗ | ✗ | ✗ |
+| Token | ✓ (TLS req) | ✓ (TLS req) | ✓ (TLS req) | ✗ | ✗ | ✗ |
+| SCRAM | ✗ | ✗ | ✗ | ✓ | ✓ | ✗ |
+| mTLS | ✓ | ✓ | ✓ | ✗ | ✗ | ✗ |
+
+**Important Notes:**
+- HTTP authentication **requires** TLS to be enabled
+- TCP connections are **always** unencrypted
+- TCP Sink has **no** authentication (debugging only)
+
+## Basic Authentication
+
+HTTP/HTTPS connections with username/password.
+
+### Configuration
+
+```toml
+[pipelines.sources.http.auth]
+type = "basic"
+realm = "LogWisp"
+
+[[pipelines.sources.http.auth.basic.users]]
+username = "admin"
+password_hash = "$argon2id$v=19$m=65536,t=3,p=2$..."
+```
+
+### Generating Credentials
+
+Use the `auth` command:
+```bash
+logwisp auth -u admin -b
+```
+
+Output includes:
+- Argon2id password hash for configuration
+- TOML configuration snippet
+
+### Password Hash Format
+
+LogWisp uses Argon2id with parameters:
+- Memory: 65536 KB
+- Iterations: 3
+- Parallelism: 2
+- Salt: Random 16 bytes
+
+## Token Authentication
+
+Bearer token authentication for HTTP/HTTPS.
+
+### Configuration
+
+```toml
+[pipelines.sources.http.auth]
+type = "token"
+
+[pipelines.sources.http.auth.token]
+tokens = ["token1", "token2", "token3"]
+```
+
+### Generating Tokens
+
+```bash
+logwisp auth -k -l 32
+```
+
+Generates:
+- Base64-encoded token
+- Hex-encoded token
+- Configuration snippet
+
+### Token Usage
+
+Include in requests:
+```
+Authorization: Bearer <token>
+```
+
+## SCRAM Authentication
+
+Secure Challenge-Response for TCP connections.
+
+### Configuration
+
+```toml
+[pipelines.sources.tcp.auth]
+type = "scram"
+
+[[pipelines.sources.tcp.auth.scram.users]]
+username = "tcpuser"
+stored_key = "base64..."
+server_key = "base64..."
+salt = "base64..."
+argon_time = 3
+argon_memory = 65536
+argon_threads = 4
+```
+
+### Generating SCRAM Credentials
+
+```bash
+logwisp auth -u tcpuser -s
+```
+
+### SCRAM Features
+
+- Argon2-SCRAM-SHA256 algorithm
+- Challenge-response mechanism
+- No password transmission
+- Replay attack protection
+- Works over unencrypted connections
+
+## mTLS (Mutual TLS)
+
+Certificate-based authentication for HTTPS.
+
+### Server Configuration
+
+```toml
+[pipelines.sources.http.tls]
+enabled = true
+cert_file = "/path/to/server.pem"
+key_file = "/path/to/server.key"
+client_auth = true
+client_ca_file = "/path/to/ca.pem"
+verify_client_cert = true
+
+[pipelines.sources.http.auth]
+type = "mtls"
+```
+
+### Client Configuration
+
+```toml
+[pipelines.sinks.http_client.tls]
+enabled = true
+cert_file = "/path/to/client.pem"
+key_file = "/path/to/client.key"
+
+[pipelines.sinks.http_client.auth]
+type = "mtls"
+```
+
+### Certificate Generation
+
+Use the `tls` command:
+```bash
+# Generate CA
+logwisp tls -ca -o ca
+
+# Generate server certificate
+logwisp tls -server -ca-cert ca.pem -ca-key ca.key -host localhost -o server
+
+# Generate client certificate
+logwisp tls -client -ca-cert ca.pem -ca-key ca.key -o client
+```
+
+## Authentication Command
+
+### Usage
+
+```bash
+logwisp auth [options]
+```
+
+### Options
+
+| Flag | Description |
+|------|-------------|
+| `-u, --user` | Username for credential generation |
+| `-p, --password` | Password (prompts if not provided) |
+| `-b, --basic` | Generate basic auth (HTTP/HTTPS) |
+| `-s, --scram` | Generate SCRAM auth (TCP) |
+| `-k, --token` | Generate bearer token |
+| `-l, --length` | Token length in bytes (default: 32) |
+
+### Security Best Practices
+
+1. **Always use TLS** for HTTP authentication
+2. **Never hardcode passwords** in configuration
+3. **Use strong passwords** (minimum 12 characters)
+4. **Rotate tokens regularly**
+5. **Limit user permissions** to minimum required
+6. **Store password hashes only**, never plaintext
+7. **Use unique credentials** per service/user
+
+## Access Control Lists
+
+Combine authentication with IP-based access control:
+
+```toml
+[pipelines.sources.http.net_limit]
+enabled = true
+ip_whitelist = ["192.168.1.0/24", "10.0.0.0/8"]
+ip_blacklist = ["192.168.1.100"]
+```
+
+Priority order:
+1. Blacklist (checked first, immediate deny)
+2. Whitelist (if configured, must match)
+3. Authentication (if configured)
+
+## Credential Storage
+
+### Configuration File
+
+Store hashes in TOML:
+```toml
+[[pipelines.sources.http.auth.basic.users]]
+username = "admin"
+password_hash = "$argon2id$..."
+```
+
+### Environment Variables
+
+Override via environment:

-## Hot Reload
+## Logging Configuration
 
-LogWisp supports automatic configuration reloading without restart:
+LogWisp's internal operational logging:
-
-```bash
-# Enable hot reload
-logwisp --config-auto-reload --config /etc/logwisp/config.toml
-
-# Manual reload via signal
-kill -HUP $(pidof logwisp)  # or SIGUSR1
-```
-
-Hot reload updates:
-- Pipeline configurations
-- Filters
-- Formatters
-- Rate limits
-- Router mode changes
-
-Not reloaded (requires restart):
-- Logging configuration
-- Background mode
-
-## Configuration Structure
 
 ```toml
-# Optional: Enable router mode
-router = false
-
-# Optional: Background mode
-background = false
-
-# Optional: Quiet mode
-quiet = false
-
-# Optional: Disable status reporter
-disable_status_reporter = false
-
-# Optional: LogWisp's own logging
 [logging]
-output = "stderr"  # file, stdout, stderr, both, none
+output = "stdout"  # file|stdout|stderr|split|all|none
-level = "info"     # debug, info, warn, error
+level = "info"     # debug|info|warn|error
 
 [logging.file]
-directory = "./logs"
+directory = "./log"
 name = "logwisp"
 max_size_mb = 100
 max_total_size_mb = 1000
-retention_hours = 168
+retention_hours = 168.0
 
 [logging.console]
-target = "stderr"  # stdout, stderr, split
+target = "stdout"  # stdout|stderr|split
-format = "txt"     # txt or json
+format = "txt"     # txt|json
+```
 
-# Required: At least one pipeline
+### Output Modes
+
+- **file**: Write to log files only
+- **stdout**: Write to standard output
+- **stderr**: Write to standard error
+- **split**: INFO/DEBUG to stdout, WARN/ERROR to stderr
+- **all**: Write to both file and console
+- **none**: Disable all logging
+
+## Pipeline Configuration
+
+Each `[[pipelines]]` section defines an independent processing pipeline:
+
+```toml
 [[pipelines]]
-name = "default"
+name = "pipeline-name"
 
-# Sources (required)
+# Rate limiting (optional)
+[pipelines.rate_limit]
+rate = 1000.0
+burst = 2000.0
+policy = "drop"  # pass|drop
+max_entry_size_bytes = 0  # 0=unlimited
+
+# Format configuration (optional)
+[pipelines.format]
+type = "json"  # raw|json|txt
+
+# Sources (required, 1+)
 [[pipelines.sources]]
 type = "directory"
-options = { ... }
+# ... source-specific config
 
 # Filters (optional)
 [[pipelines.filters]]
 type = "include"
-patterns = [...]
+logic = "or"
+patterns = ["ERROR", "WARN"]
 
-# Sinks (required)
+# Sinks (required, 1+)
 [[pipelines.sinks]]
 type = "http"
-options = { ... }
+# ... sink-specific config
 ```
 
-## Pipeline Configuration
+## Environment Variables
 
-Each `[[pipelines]]` section defines an independent processing pipeline.
+All configuration options support environment variable overrides:
 
-### Pipeline Formatters
+### Naming Convention
 
-Control output format per pipeline:
+- Prefix: `LOGWISP_`
+- Path separator: `_` (underscore)
+- Array indices: Numeric suffix (0-based)
+- Case: UPPERCASE
 
-```toml
+### Mapping Examples
-[[pipelines]]
-name = "json-output"
-format = "json"  # raw, json, text
 
-[pipelines.format_options]
+| TOML Path | Environment Variable |
-# JSON formatter
+|-----------|---------------------|
-pretty = false
+| `quiet` | `LOGWISP_QUIET` |
-timestamp_field = "timestamp"
+| `logging.level` | `LOGWISP_LOGGING_LEVEL` |
-level_field = "level"
+| `pipelines[0].name` | `LOGWISP_PIPELINES_0_NAME` |
-message_field = "message"
+| `pipelines[0].sources[0].type` | `LOGWISP_PIPELINES_0_SOURCES_0_TYPE` |
-source_field = "source"
 
-# Text formatter
+## Command-Line Overrides
-template = "[{{.Timestamp | FmtTime}}] [{{.Level | ToUpper}}] {{.Message}}"
+
-timestamp_format = "2006-01-02T15:04:05Z07:00"
+All configuration options can be overridden via CLI flags:
+
+```bash
+logwisp --quiet \
+  --logging.level=debug \
+  --pipelines.0.name=myapp \
+  --pipelines.0.sources.0.type=stdin
 ```
 
-### Sources
+## Configuration Validation
 
-Input data sources:
+LogWisp validates configuration at startup:
+- Required fields presence
+- Type correctness
+- Port conflicts
+- Path accessibility
+- Pattern compilation
+- Network address formats

-### Filters
-
-Control which log entries pass through:

-# Filter Guide
+# Filters
 
-LogWisp filters control which log entries pass through pipelines using regular expressions.
+LogWisp filters control which log entries pass through the pipeline using pattern matching.
 
-## How Filters Work
+## Filter Types
 
-- **Include**: Only matching logs pass (whitelist)
+### Include Filter
-- **Exclude**: Matching logs are dropped (blacklist)
-- Multiple filters apply sequentially - all must pass
 
-## Configuration
+Only entries matching patterns pass through.
 
-```toml
-[[pipelines.filters]]
-type = "include"    # or "exclude"
-logic = "or"        # or "and"
-patterns = [
-    "pattern1",
-    "pattern2"
-]
-```
-
-### Filter Types
-
-#### Include Filter
 ```toml
 [[pipelines.filters]]
 type = "include"
-logic = "or"
+logic = "or"  # or|and
-patterns = ["ERROR", "WARN", "CRITICAL"]
+patterns = [
-# Only ERROR, WARN, or CRITICAL logs pass
+    "ERROR",
+    "WARN",
+    "CRITICAL"
+]
 ```
 
-#### Exclude Filter
+### Exclude Filter
+
+Entries matching patterns are dropped.
+
 ```toml
 [[pipelines.filters]]
 type = "exclude"
-patterns = ["DEBUG", "TRACE", "/health"]
+patterns = [
-# DEBUG, TRACE, and health checks are dropped
+    "DEBUG",
+    "TRACE",
+    "health-check"
+]
 ```
 
-### Logic Operators
+## Configuration Options
 
-- **OR**: Match ANY pattern (default)
+| Option | Type | Default | Description |
-- **AND**: Match ALL patterns
+|--------|------|---------|-------------|
-
+| `type` | string | Required | Filter type (include/exclude) |
-```toml
+| `logic` | string | "or" | Pattern matching logic (or/and) |
-# OR Logic
+| `patterns` | []string | Required | Pattern list |
-logic = "or"
-patterns = ["ERROR", "FAIL"]
-# Matches: "ERROR: disk full" OR "FAIL: timeout"
-
-# AND Logic
-logic = "and"
-patterns = ["database", "timeout", "ERROR"]
-# Matches: "ERROR: database connection timeout"
-# Not: "ERROR: file not found"
-```
 
 ## Pattern Syntax
 
-Go regular expressions (RE2):
+Patterns support regular expression syntax:
 
+### Basic Patterns
+- **Literal match**: `"ERROR"` - matches "ERROR" anywhere
+- **Case-insensitive**: `"(?i)error"` - matches "error", "ERROR", "Error"
+- **Word boundary**: `"\\berror\\b"` - matches whole word only
+
+### Advanced Patterns
+- **Alternation**: `"ERROR|WARN|FATAL"`
+- **Character classes**: `"[0-9]{3}"`
+- **Wildcards**: `".*exception.*"`
+- **Line anchors**: `"^ERROR"` (start), `"ERROR$"` (end)
+
+### Special Characters
+Escape special regex characters with backslash:
+- `.` → `\\.`
+- `*` → `\\*`
+- `[` → `\\[`
+- `(` → `\\(`
+
+## Filter Logic
+
+### OR Logic (default)
+Entry passes if ANY pattern matches:
 ```toml
-"ERROR"              # Substring match
+logic = "or"
-"(?i)error"          # Case-insensitive
+patterns = ["ERROR", "WARN"]
-"\\berror\\b"        # Word boundaries
+# Passes: "ERROR in module", "WARN: low memory"
-"^ERROR"             # Start of line
+# Blocks: "INFO: started"
-"ERROR$"             # End of line
-"error|fail|warn"    # Alternatives
 ```
 
-## Common Patterns
+### AND Logic
-
+Entry passes only if ALL patterns match:
-### Log Levels
 ```toml
-patterns = [
+logic = "and"  
-    "\\[(ERROR|WARN|INFO)\\]",      # [ERROR] format
+patterns = ["database", "ERROR"]
-    "(?i)\\b(error|warning)\\b",    # Word boundaries
+# Passes: "ERROR: database connection failed"
-    "level=(error|warn)",           # key=value format
+# Blocks: "ERROR: file not found"
-]
 ```
 
-### Application Errors
+## Filter Chain
+
+Multiple filters execute sequentially:
+
 ```toml
-# Java
+# First filter: Include errors and warnings
-patterns = [
-    "Exception",
-    "at .+\\.java:[0-9]+",
-    "NullPointerException"
-]
-
-# Python
-patterns = [
-    "Traceback",
-    "File \".+\\.py\", line [0-9]+",
-    "ValueError|TypeError"
-]
-
-# Go
-patterns = [
-    "panic:",
-    "goroutine [0-9]+",
-    "runtime error:"
-]
-```
-
-### Performance Issues
-```toml
-patterns = [
-    "took [0-9]{4,}ms",           # >999ms operations
-    "timeout|timed out",
-    "slow query",
-    "high cpu|cpu usage: [8-9][0-9]%"
-]
-```
-
-### HTTP Patterns
-```toml
-patterns = [
-    "status[=:][4-5][0-9]{2}",    # 4xx/5xx codes
-    "HTTP/[0-9.]+ [4-5][0-9]{2}",
-    "\"/api/v[0-9]+/",            # API paths
-]
-```
-
-## Filter Chains
-
-### Error Monitoring
-```toml
-# Include errors
 [[pipelines.filters]]
 type = "include"
-patterns = ["(?i)\\b(error|fail|critical)\\b"]
+patterns = ["ERROR", "WARN"]
 
-# Exclude known non-issues
+# Second filter: Exclude test environments
 [[pipelines.filters]]
 type = "exclude"
-patterns = ["Error: Expected", "/health"]
+patterns = ["test-env", "staging"]
 ```
 
-### API Monitoring
+Processing order:
+1. Entry arrives from source
+2. Include filter evaluates
+3. If passed, exclude filter evaluates
+4. If passed all filters, entry continues to sink
+
+## Performance Considerations
+
+### Pattern Compilation
+- Patterns compile once at startup
+- Invalid patterns cause startup failure
+- Complex patterns may impact performance
+
+### Optimization Tips
+- Place most selective filters first
+- Use simple patterns when possible
+- Combine related patterns with alternation
+- Avoid excessive wildcards (`.*`)
+
+## Filter Statistics
+
+Filters track:
+- Total entries evaluated
+- Entries passed
+- Entries blocked
+- Processing time per pattern
+
+## Common Use Cases
+
+### Log Level Filtering
 ```toml
-# Include API calls
 [[pipelines.filters]]
 type = "include"
-patterns = ["/api/", "/v[0-9]+/"]
+patterns = ["ERROR", "WARN", "FATAL", "CRITICAL"]
+```
 
-# Exclude successful
+### Application Filtering
+```toml
+[[pipelines.filters]]
+type = "include"
+patterns = ["app1", "app2", "app3"]
+```
+
+### Noise Reduction
+```toml
 [[pipelines.filters]]
 type = "exclude"
-patterns = ["\" 2[0-9]{2} "]
+patterns = [
+    "health-check",
+    "ping",
+    "/metrics",
+    "heartbeat"
+]
 ```
 
-## Performance Tips
+### Security Filtering
-
+```toml
-1. **Use anchors**: `^ERROR` faster than `ERROR`
+[[pipelines.filters]]
-2. **Avoid nested quantifiers**: `((a+)+)+`
+type = "exclude"
-3. **Non-capturing groups**: `(?:error|warn)`
+patterns = [
-4. **Order by frequency**: Most common first
+    "password",
-5. **Simple patterns**: Faster than complex regex
+    "token",
-
+    "api[_-]key",
-## Testing Filters
+    "secret"
-
+]
-```bash
-# Test configuration
-echo "[ERROR] Test" >> test.log
-echo "[INFO] Test" >> test.log
-
-# Run with debug
-logwisp --log-level debug
-
-# Check output
-curl -N http://localhost:8080/stream
 ```
 
-## Regex Pattern Guide
+### Multi-stage Filtering
+```toml
+# Include production logs
+[[pipelines.filters]]
+type = "include"
+patterns = ["prod-", "production"]
 
-LogWisp uses Go's standard regex engine (RE2). It includes most common features but omits backtracking-heavy syntax.
+# Include only errors
+[[pipelines.filters]]
+type = "include"
+patterns = ["ERROR", "EXCEPTION", "FATAL"]
 
-For complex logic, chain multiple filters (e.g., an `include` followed by an `exclude`) rather than writing one complex regex.
+# Exclude known issues
-
+[[pipelines.filters]]
-### Basic Matching
+type = "exclude"
-
+patterns = ["ECONNRESET", "broken pipe"]
-| Pattern | Description | Example |
-| :--- | :--- | :--- |
-| `literal` | Matches the exact text. | `"ERROR"` matches any log with "ERROR". |
-| `.` | Matches any single character (except newline). | `"user."` matches "userA", "userB", etc. |
-| `a\|b` | Matches expression `a` OR expression `b`. | `"error\|fail"` matches lines with "error" or "fail". |
-
-### Anchors and Boundaries
-
-Anchors tie your pattern to a specific position in the line.
-
-| Pattern | Description | Example |
-| :--- | :--- | :--- |
-| `^` | Matches the beginning of the line. | `"^ERROR"` matches lines *starting* with "ERROR". |
-| `$` | Matches the end of the line. | `"crashed$"` matches lines *ending* with "crashed". |
-| `\b` | Matches a word boundary. | `"\berror\b"` matches "error" but not "terrorist". |
-
-### Character Classes
-
-| Pattern | Description | Example |
-| :--- | :--- | :--- |
-| `[abc]` | Matches `a`, `b`, or `c`. | `"[aeiou]"` matches any vowel. |
-| `[^abc]` | Matches any character *except* `a`, `b`, or `c`. | `"[^0-9]"` matches any non-digit. |
-| `[a-z]` | Matches any character in the range `a` to `z`. | `"[a-zA-Z]"` matches any letter. |
-| `\d` | Matches any digit (`[0-9]`). | `\d{3}` matches three digits, like "123". |
-| `\w` | Matches any word character (`[a-zA-Z0-9_]`). | `\w+` matches one or more word characters. |
-| `\s` | Matches any whitespace character. | `\s+` matches one or more spaces or tabs. |
-
-### Quantifiers
-
-Quantifiers specify how many times a character or group must appear.
-
-| Pattern | Description | Example |
-| :--- | :--- | :--- |
-| `*` | Zero or more times. | `"a*"` matches "", "a", "aa". |
-| `+` | One or more times. | `"a+"` matches "a", "aa", but not "". |
-| `?` | Zero or one time. | `"colou?r"` matches "color" and "colour". |
-| `{n}` | Exactly `n` times. | `\d{4}` matches a 4-digit number. |
-| `{n,}` | `n` or more times. | `\d{2,}` matches numbers with 2 or more digits. |
-| `{n,m}` | Between `n` and `m` times. | `\d{1,3}` matches numbers with 1 to 3 digits. |
-
-### Grouping
-
-| Pattern | Description | Example |
-| :--- | :--- | :--- |
-| `(...)` | Groups an expression and captures the match. | `(ERROR|WARN)` captures "ERROR" or "WARN". |
-| `(?:...)`| Groups an expression *without* capturing. Faster. | `(?:ERROR|WARN)` is more efficient if you just need to group. |
-
-### Flags and Modifiers
-
-Flags are placed at the beginning of a pattern to change its behavior.
-
-| Pattern | Description |
-| :--- | :--- |
-| `(?i)` | Case-insensitive matching. |
-| `(?m)` | Multi-line mode (`^` and `$` match start/end of lines). |
-
-**Example:** `"(?i)error"` matches "error", "ERROR", and "Error".
-
-### Practical Examples for Logging
-
-*   **Match an IP Address:**
-    ```
-    \b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b
-    ```
-
-*   **Match HTTP 4xx or 5xx Status Codes:**
-    ```
-    "status[= ](4|5)\d{2}"
-    ```
-
-*   **Match a slow database query (>100ms):**
-    ```
-    "Query took [1-9]\d{2,}ms"
-    ```
-
-*   **Match key-value pairs:**
-    ```
-    "user=(admin|guest)"
-    ```
-
-*   **Match Java exceptions:**
-    ```
-    "Exception:|at .+\.java:\d+"

+# Formatters
+
+LogWisp formatters transform log entries before output to sinks.
+
+## Formatter Types
+
+### Raw Formatter
+
+Outputs the log message as-is with optional newline.
+
+```toml
+[pipelines.format]
+type = "raw"
+
+[pipelines.format.raw]
+add_new_line = true
+```
+
+**Configuration Options:**
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `add_new_line` | bool | true | Append newline to messages |
+
+### JSON Formatter
+
+Produces structured JSON output.
+
+```toml
+[pipelines.format]
+type = "json"
+
+[pipelines.format.json]
+pretty = false
+timestamp_field = "timestamp"
+level_field = "level"
+message_field = "message"
+source_field = "source"
+```
+
+**Configuration Options:**
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `pretty` | bool | false | Pretty print JSON |
+| `timestamp_field` | string | "timestamp" | Field name for timestamp |
+| `level_field` | string | "level" | Field name for log level |
+| `message_field` | string | "message" | Field name for message |
+| `source_field` | string | "source" | Field name for source |
+
+**Output Structure:**
+```json
+{
+  "timestamp": "2024-01-01T12:00:00Z",
+  "level": "ERROR",
+  "source": "app",
+  "message": "Connection failed"
+}
+```
+
+### Text Formatter
+
+Template-based text formatting.
+
+```toml
+[pipelines.format]
+type = "txt"
+
+[pipelines.format.txt]
+template = "[{{.Timestamp | FmtTime}}] [{{.Level | ToUpper}}] {{.Source}} - {{.Message}}"
+timestamp_format = "2006-01-02T15:04:05.000Z07:00"
+```
+
+**Configuration Options:**
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `template` | string | See below | Go template string |
+| `timestamp_format` | string | RFC3339 | Go time format string |
+
+**Default Template:**
+```
+[{{.Timestamp | FmtTime}}] [{{.Level | ToUpper}}] {{.Source}} - {{.Message}}{{ if .Fields }} {{.Fields}}{{ end }}
+```
+
+## Template Functions
+
+Available functions in text templates:
+
+| Function | Description | Example |
+|----------|-------------|---------|
+| `FmtTime` | Format timestamp | `{{.Timestamp \| FmtTime}}` |
+| `ToUpper` | Convert to uppercase | `{{.Level \| ToUpper}}` |
+| `ToLower` | Convert to lowercase | `{{.Source \| ToLower}}` |
+| `TrimSpace` | Remove whitespace | `{{.Message \| TrimSpace}}` |
+
+## Template Variables
+
+Available variables in templates:
+
+| Variable | Type | Description |
+|----------|------|-------------|
+| `.Timestamp` | time.Time | Entry timestamp |
+| `.Level` | string | Log level |
+| `.Source` | string | Source identifier |
+| `.Message` | string | Log message |
+| `.Fields` | string | Additional fields (JSON) |
+
+## Time Format Strings
+
+Common Go time format patterns:
+
+| Pattern | Example Output |
+|---------|---------------|
+| `2006-01-02T15:04:05Z07:00` | 2024-01-02T15:04:05Z |
+| `2006-01-02 15:04:05` | 2024-01-02 15:04:05 |
+| `Jan 2 15:04:05` | Jan 2 15:04:05 |
+| `15:04:05.000` | 15:04:05.123 |
+| `2006/01/02` | 2024/01/02 |
+
+## Format Selection
+
+### Default Behavior
+
+If no formatter specified:
+- **HTTP/TCP sinks**: JSON format
+- **Console/File sinks**: Raw format
+- **Client sinks**: JSON format
+
+### Per-Pipeline Configuration
+
+Each pipeline can have its own formatter:
+
+```toml
+[[pipelines]]
+name = "json-pipeline"
+[pipelines.format]
+type = "json"
+
+[[pipelines]]
+name = "text-pipeline"
+[pipelines.format]
+type = "txt"
+```
+
+## Message Processing
+
+### JSON Message Handling
+
+When using JSON formatter with JSON log messages:
+1. Attempts to parse message as JSON
+2. Merges fields with LogWisp metadata
+3. LogWisp fields take precedence
+4. Falls back to string if parsing fails
+
+### Field Preservation
+
+LogWisp metadata always includes:
+- Timestamp (from source or current time)
+- Level (detected or default)
+- Source (origin identifier)
+- Message (original content)
+
+## Performance Characteristics
+
+### Formatter Performance
+
+Relative performance (fastest to slowest):
+1. **Raw**: Direct passthrough
+2. **Text**: Template execution
+3. **JSON**: Serialization
+4. **JSON (pretty)**: Formatted serialization
+
+### Optimization Tips
+
+- Use raw format for high throughput
+- Cache template compilation (automatic)
+- Minimize template complexity
+- Avoid pretty JSON in production
+
+## Common Configurations
+
+### Structured Logging
+```toml
+[pipelines.format]
+type = "json"
+[pipelines.format.json]
+pretty = false
+```
+
+### Human-Readable Logs
+```toml
+[pipelines.format]
+type = "txt"
+[pipelines.format.txt]
+template = "{{.Timestamp | FmtTime}} [{{.Level}}] {{.Message}}"
+timestamp_format = "15:04:05"
+```
+
+### Syslog Format
+```toml
+[pipelines.format]
+type = "txt"
+[pipelines.format.txt]
+template = "{{.Timestamp | FmtTime}} {{.Source}} {{.Level}}: {{.Message}}"
+timestamp_format = "Jan 2 15:04:05"
+```
+
+### Minimal Output
+```toml
+[pipelines.format]
+type = "txt"
+[pipelines.format.txt]
+template = "{{.Message}}"
+```

+| `-client` | Generate client certificate |
+| `-host` | Comma-separated hostnames/IPs |
+| `-o` | Output file prefix |
+| `-days` | Certificate validity (default: 365) |
+
+## Network Rate Limiting
+
+### Configuration Options
+
+```toml
+[pipelines.sources.http.net_limit]
+enabled = true
+max_connections_per_ip = 10
+max_connections_total = 100
+requests_per_second = 100.0
+burst_size = 200
+response_code = 429
+response_message = "Rate limit exceeded"
+ip_whitelist = ["192.168.1.0/24"]
+ip_blacklist = ["10.0.0.0/8"]
+```
+
+### Rate Limiting Parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `enabled` | bool | Enable rate limiting |
+| `max_connections_per_ip` | int | Per-IP connection limit |
+| `max_connections_total` | int | Global connection limit |
+| `requests_per_second` | float | Request rate limit |
+| `burst_size` | int | Token bucket burst capacity |
+| `response_code` | int | HTTP response code when limited |
+| `response_message` | string | Response message when limited |
+
+### IP Access Control
+
+**Whitelist**: Only specified IPs/networks allowed
+```toml
+ip_whitelist = [
+    "192.168.1.0/24",  # Local network
+    "10.0.0.0/8",      # Private network
+    "203.0.113.5"      # Specific IP
+]
+```
+
+**Blacklist**: Specified IPs/networks denied
+```toml
+ip_blacklist = [
+    "192.168.1.100",   # Blocked host
+    "10.0.0.0/16"      # Blocked subnet
+]
+```
+
+Processing order:
+1. Blacklist (immediate deny if matched)
+2. Whitelist (must match if configured)
+3. Rate limiting
+4. Authentication
+
+## Connection Management
+
+### TCP Keep-Alive
+
+```toml
+[pipelines.sources.tcp]
+keep_alive = true
+keep_alive_period_ms = 30000  # 30 seconds
+```
+
+Benefits:
+- Detect dead connections
+- Prevent connection timeout
+- Maintain NAT mappings
+
+### Connection Timeouts
+
+```toml
+[pipelines.sources.http]
+read_timeout_ms = 10000   # 10 seconds
+write_timeout_ms = 10000  # 10 seconds
+
+[pipelines.sinks.tcp_client]
+dial_timeout = 10         # Connection timeout
+write_timeout = 30        # Write timeout
+read_timeout = 10         # Read timeout
+```
+
+### Connection Limits
+
+Global limits:
+```toml
+max_connections = 100     # Total concurrent connections
+```
+
+Per-IP limits:
+```toml
+max_connections_per_ip = 10
+```
+
+## Heartbeat Configuration
+
+Keep connections alive with periodic heartbeats:
+
+### HTTP Sink Heartbeat
+
+```toml
+[pipelines.sinks.http.heartbeat]
+enabled = true
+interval_ms = 30000
+include_timestamp = true
+include_stats = false
+format = "comment"  # comment|event|json
+```
+
+Formats:
+- **comment**: SSE comment (`: heartbeat`)
+- **event**: SSE event with data
+- **json**: JSON-formatted heartbeat
+
+### TCP Sink Heartbeat
+
+```toml
+[pipelines.sinks.tcp.heartbeat]
+enabled = true
+interval_ms = 30000
+include_timestamp = true
+include_stats = false
+format = "json"  # json|txt
+```
+
+## Network Protocols
+
+### HTTP/HTTPS
+
+- HTTP/1.1 and HTTP/2 support
+- Persistent connections
+- Chunked transfer encoding
+- Server-Sent Events (SSE)
+
+### TCP
+
+- Raw TCP sockets
+- Newline-delimited protocol
+- Binary-safe transmission
+- No encryption available
+
+## Port Configuration
+
+### Default Ports
+
+| Service | Default Port | Protocol |
+|---------|--------------|----------|
+| HTTP Source | 8081 | HTTP/HTTPS |
+| HTTP Sink | 8080 | HTTP/HTTPS |
+| TCP Source | 9091 | TCP |
+| TCP Sink | 9090 | TCP |
+
+### Port Conflict Prevention
+
+LogWisp validates port usage at startup:
+- Detects port conflicts across pipelines
+- Prevents duplicate bindings
+- Suggests alternative ports
+
+## Network Security
+
+### Best Practices
+
+1. **Use TLS for HTTP** connections when possible
+2. **Implement rate limiting** to prevent DoS
+3. **Configure IP whitelists** for restricted access
+4. **Enable authentication** for all network endpoints
+5. **Use non-standard ports** to reduce scanning exposure
+6. **Monitor connection metrics** for anomalies
+7. **Set appropriate timeouts** to prevent resource exhaustion
+
+### Security Warnings
+
+- TCP connections are **always unencrypted**
+- HTTP Basic/Token auth **requires TLS**
+- Avoid `skip_verify` in production
+- Never expose unauthenticated endpoints publicly
+
+## Load Balancing
+
+### Client-Side Load Balancing
+
+Configure multiple endpoints (future feature):
+```toml
+[[pipelines.sinks.http_client]]
+urls = [
+    "https://log1.example.com/ingest",
+    "https://log2.example.com/ingest"
+]
+strategy = "round-robin"  # round-robin|random|least-conn
+```
+
+### Server-Side Considerations
+
+- Use reverse proxy for load distribution
+- Configure session affinity if needed
+- Monitor individual instance health
+
+## Troubleshooting
+
+### Common Issues
+
+**Connection Refused**
+- Check firewall rules
+- Verify service is running
+- Confirm correct port/host
+
+**TLS Handshake Failure**
+- Verify certificate validity
+- Check certificate chain
+- Confirm TLS versions match
+
+**Rate Limit Exceeded**
+- Adjust rate limit parameters
+- Add IP to whitelist
+- Implement client-side throttling
+
+**Connection Timeout**
+- Increase timeout values
+- Check network latency
+- Verify keep-alive settings

+# Operations Guide
+
+Running, monitoring, and maintaining LogWisp in production.
+
+## Starting LogWisp
+
+### Manual Start
+
+```bash
+# Foreground with default config
+logwisp
+
+# Background mode
+logwisp --background
+
+# With specific configuration
+logwisp --config /etc/logwisp/production.toml
+```
+
+### Service Management
+
+**Linux (systemd):**
+```bash
+sudo systemctl start logwisp
+sudo systemctl stop logwisp
+sudo systemctl restart logwisp
+sudo systemctl status logwisp
+```
+
+**FreeBSD (rc.d):**
+```bash
+sudo service logwisp start
+sudo service logwisp stop
+sudo service logwisp restart
+sudo service logwisp status
+```
+
+## Configuration Management
+
+### Hot Reload
+
+Enable automatic configuration reload:
+```toml
+config_auto_reload = true
+```
+
+Or via command line:
+```bash
+logwisp --config-auto-reload
+```
+
+Trigger manual reload:
+```bash
+kill -HUP $(pidof logwisp)
+# or
+kill -USR1 $(pidof logwisp)
+```
+
+### Configuration Validation
+
+Test configuration without starting:
+```bash
+logwisp --config test.toml --quiet --disable-status-reporter
+```
+
+Check for errors:
+- Port conflicts
+- Invalid patterns
+- Missing required fields
+- File permissions
+
+## Monitoring
+
+### Status Reporter
+
+Built-in periodic status logging (30-second intervals):
+
+```
+[INFO] Status report active_pipelines=2 time=15:04:05
+[INFO] Pipeline status pipeline=app entries_processed=10523
+[INFO] Pipeline status pipeline=system entries_processed=5231
+```
+
+Disable if not needed:
+```toml
+disable_status_reporter = true
+```
+
+### HTTP Status Endpoint
+
+When using HTTP sink:
+```bash
+curl http://localhost:8080/status | jq .
+```
+
+Response structure:
+```json
+{
+  "uptime": "2h15m30s",
+  "pipelines": {
+    "default": {
+      "sources": 1,
+      "sinks": 2,
+      "processed": 15234,
+      "filtered": 523,
+      "dropped": 12
+    }
+  }
+}
+```
+
+### Metrics Collection
+
+Track via logs:
+- Total entries processed
+- Entries filtered
+- Entries dropped
+- Active connections
+- Buffer utilization
+
+## Log Management
+
+### LogWisp's Operational Logs
+
+Configuration for LogWisp's own logs:
+
+```toml
+[logging]
+output = "file"
+level = "info"
+
+[logging.file]
+directory = "/var/log/logwisp"
+name = "logwisp"
+max_size_mb = 100
+retention_hours = 168
+```
+
+### Log Rotation
+
+Automatic rotation based on:
+- File size threshold
+- Total size limit
+- Retention period
+
+Manual rotation:
+```bash
+# Move current log
+mv /var/log/logwisp/logwisp.log /var/log/logwisp/logwisp.log.1
+# Send signal to reopen
+kill -USR1 $(pidof logwisp)
+```
+
+### Log Levels
+
+Operational log levels:
+- **debug**: Detailed debugging information
+- **info**: General operational messages
+- **warn**: Warning conditions
+- **error**: Error conditions
+
+Production recommendation: `info` or `warn`
+
+## Performance Tuning
+
+### Buffer Sizing
+
+Adjust buffers based on load:
+
+```toml
+# High-volume source
+[[pipelines.sources]]
+type = "http"
+[pipelines.sources.http]
+buffer_size = 5000  # Increase for burst traffic
+
+# Slow consumer sink
+[[pipelines.sinks]]
+type = "http_client"
+[pipelines.sinks.http_client]
+buffer_size = 10000  # Larger buffer for slow endpoints
+batch_size = 500     # Larger batches
+```
+
+### Rate Limiting
+
+Protect against overload:
+
+```toml
+[pipelines.rate_limit]
+rate = 1000.0        # Entries per second
+burst = 2000.0       # Burst capacity
+policy = "drop"      # Drop excess entries
+```
+
+### Connection Limits
+
+Prevent resource exhaustion:
+
+```toml
+[pipelines.sources.http.net_limit]
+max_connections_total = 1000
+max_connections_per_ip = 50
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**High Memory Usage**
+- Check buffer sizes
+- Monitor goroutine count
+- Review retention settings
+
+**Dropped Entries**
+- Increase buffer sizes
+- Add rate limiting
+- Check sink performance
+
+**Connection Errors**
+- Verify network connectivity
+- Check firewall rules
+- Review TLS certificates
+
+### Debug Mode
+
+Enable detailed logging:
+```bash
+logwisp --logging.level=debug --logging.output=stderr
+```
+
+### Health Checks
+
+Implement external monitoring:
+```bash
+#!/bin/bash
+# Health check script
+if ! curl -sf http://localhost:8080/status > /dev/null; then
+  echo "LogWisp health check failed"
+  exit 1
+fi
+```
+
+## Backup and Recovery
+
+### Configuration Backup
+
+```bash
+# Backup configuration
+cp /etc/logwisp/logwisp.toml /backup/logwisp-$(date +%Y%m%d).toml
+
+# Version control
+git add /etc/logwisp/
+git commit -m "LogWisp config update"
+```
+
+### State Recovery
+
+LogWisp maintains minimal state:
+- File read positions (automatic)
+- Connection state (automatic)
+
+Recovery after crash:
+1. Service automatically restarts (systemd/rc.d)
+2. File sources resume from last position
+3. Network sources accept new connections
+4. Clients reconnect automatically
+
+## Security Operations
+
+### Certificate Management
+
+Monitor certificate expiration:
+```bash
+openssl x509 -in /path/to/cert.pem -noout -enddate
+```
+
+Rotate certificates:
+1. Generate new certificates
+2. Update configuration
+3. Reload service (SIGHUP)
+
+### Credential Rotation
+
+Update authentication:
+```bash
+# Generate new credentials
+logwisp auth -u admin -b
+
+# Update configuration
+vim /etc/logwisp/logwisp.toml
+
+# Reload service
+kill -HUP $(pidof logwisp)
+```
+
+### Access Auditing
+
+Monitor access patterns:
+- Review connection logs
+- Track authentication failures
+- Monitor rate limit hits
+
+## Maintenance
+
+### Planned Maintenance
+
+1. Notify users of maintenance window
+2. Stop accepting new connections
+3. Drain existing connections
+4. Perform maintenance
+5. Restart service
+
+### Upgrade Process
+
+1. Download new version
+2. Test with current configuration
+3. Stop old version
+4. Install new version
+5. Start service
+6. Verify operation
+
+### Cleanup Tasks
+
+Regular maintenance:
+- Remove old log files
+- Clean temporary files
+- Verify disk space
+- Update documentation
+
+## Disaster Recovery
+
+### Backup Strategy
+
+- Configuration files: Daily
+- TLS certificates: After generation
+- Authentication credentials: Secure storage
+
+### Recovery Procedures
+
+Service failure:
+1. Check service status
+2. Review error logs
+3. Verify configuration
+4. Restart service
+
+Data loss:
+1. Restore configuration from backup
+2. Regenerate certificates if needed
+3. Recreate authentication credentials
+4. Restart service
+

-# Quick Start Guide
-
-Get LogWisp up and running in minutes:
-
-## Installation
-
-### From Source
-```bash
-git clone https://github.com/lixenwraith/logwisp.git
-cd logwisp
-make install
-```
-
-### Using Go Install
-
-```bash
-go install github.com/lixenwraith/logwisp/src/cmd/logwisp@latest
-```
-
-## Basic Usage
-
-### 1. Monitor Current Directory
-
-Start LogWisp with defaults (monitors `*.log` files in current directory):
-
-```bash
-logwisp
-```
-
-### 2. Stream Logs
-
-Connect to the log stream:
-
-```bash
-# SSE stream
-curl -N http://localhost:8080/stream
-
-# Check status
-curl http://localhost:8080/status | jq .
-```
-
-### 3. Generate Test Logs
-
-```bash
-echo "[ERROR] Something went wrong!" >> test.log
-echo "[INFO] Application started" >> test.log
-echo "[WARN] Low memory warning" >> test.log
-```
-
-## Common Scenarios
-
-### Monitor Specific Directory
-
-Create `~/.config/logwisp/logwisp.toml`:
-
-```toml
-[[pipelines]]
-name = "myapp"
-
-[[pipelines.sources]]
-type = "directory"
-options = { path = "/var/log/myapp", pattern = "*.log" }
-
-[[pipelines.sinks]]
-type = "http"
-options = { port = 8080 }
-```
-
-### Filter Only Errors
-
-```toml
-[[pipelines]]
-name = "errors"
-
-[[pipelines.sources]]
-type = "directory"
-options = { path = "./", pattern = "*.log" }
-
-[[pipelines.filters]]
-type = "include"
-patterns = ["ERROR", "WARN", "CRITICAL"]
-
-[[pipelines.sinks]]
-type = "http"
-options = { port = 8080 }
-```
-
-### Multiple Outputs
-
-Send logs to both HTTP stream and file:
-
-```toml
-[[pipelines]]
-name = "multi-output"
-
-[[pipelines.sources]]
-type = "directory"
-options = { path = "/var/log/app", pattern = "*.log" }
-
-# HTTP streaming
-[[pipelines.sinks]]
-type = "http"
-options = { port = 8080 }
-
-# File archival
-[[pipelines.sinks]]
-type = "file"
-options = { directory = "/var/log/archive", name = "app" }
-```
-
-### TCP Streaming
-
-For high-performance streaming:
-
-```toml
-[[pipelines]]
-name = "highperf"
-
-[[pipelines.sources]]
-type = "directory"
-options = { path = "/var/log/app", pattern = "*.log" }
-
-[[pipelines.sinks]]
-type = "tcp"
-options = { port = 9090, buffer_size = 5000 }
-```
-
-Connect with netcat:
-```bash
-nc localhost 9090
-```
-
-### Router Mode
-
-Run multiple pipelines on shared ports:
-
-```bash
-logwisp --router
-
-# Access pipelines at:
-# http://localhost:8080/myapp/stream
-# http://localhost:8080/errors/stream
-# http://localhost:8080/status (global)
-```
-
-### Remote Log Collection
-
-Receive logs via HTTP/TCP and forward to remote servers:
-
-```toml
-[[pipelines]]
-name = "collector"
-
-# Receive logs via HTTP POST
-[[pipelines.sources]]
-type = "http"
-options = { port = 8081, ingest_path = "/ingest" }
-
-# Forward to remote server
-[[pipelines.sinks]]
-type = "http_client"
-options = {
-    url = "https://log-server.com/ingest",
-    batch_size = 100,
-    headers = { "Authorization" = "Bearer <API_KEY_HERE>" }
-}
-```
-
-Send logs to collector:
-```bash
-curl -X POST http://localhost:8081/ingest \
-  -H "Content-Type: application/json" \
-  -d '{"message": "Test log", "level": "INFO"}'
-```
-
-## Quick Tips
-
-### Enable Debug Logging
-```bash
-logwisp --logging.level debug --logging.output stderr
-```
-
-### Quiet Mode
-```bash
-logwisp --quiet
-```
-
-### Rate Limiting
-```toml
-[[pipelines.sinks]]
-type = "http"
-options = {
-    port = 8080,
-    rate_limit = {
-        enabled = true,
-        requests_per_second = 10.0,
-        burst_size = 20
-    }
-}
-```
-
-### Console Output
-```toml
-[[pipelines.sinks]]
-type = "stdout"  # or "stderr"
-options = {}
-```

-# Rate Limiting Guide
-
-LogWisp provides configurable rate limiting to protect against abuse and ensure fair access.
-
-## How It Works
-
-Token bucket algorithm:
-1. Each client gets a bucket with fixed capacity
-2. Tokens refill at configured rate
-3. Each request consumes one token
-4. No tokens = request rejected
-
-## Configuration
-
-```toml
-[[pipelines.sinks]]
-type = "http"  # or "tcp"
-options = {
-    port = 8080,
-    rate_limit = {
-        enabled = true,
-        requests_per_second = 10.0,
-        burst_size = 20,
-        limit_by = "ip",  # or "global"
-        max_connections_per_ip = 5,
-        max_total_connections = 100,
-        response_code = 429,
-        response_message = "Rate limit exceeded"
-    }
-}
-```
-
-## Strategies
-
-### Per-IP Limiting (Default)
-Each IP gets its own bucket:
-```toml
-limit_by = "ip"
-requests_per_second = 10.0
-# Client A: 10 req/sec
-# Client B: 10 req/sec
-```
-
-### Global Limiting
-All clients share one bucket:
-```toml
-limit_by = "global"
-requests_per_second = 50.0
-# All clients combined: 50 req/sec
-```
-
-## Connection Limits
-
-```toml
-max_connections_per_ip = 5    # Per IP
-max_total_connections = 100   # Total
-```
-
-## Response Behavior
-
-### HTTP
-Returns JSON with configured status:
-```json
-{
-    "error": "Rate limit exceeded",
-    "retry_after": "60"
-}
-```
-
-### TCP
-Connections silently dropped.
-
-## Examples
-
-### Light Protection
-```toml
-rate_limit = {
-    enabled = true,
-    requests_per_second = 50.0,
-    burst_size = 100
-}
-```
-
-### Moderate Protection
-```toml
-rate_limit = {
-    enabled = true,
-    requests_per_second = 10.0,
-    burst_size = 30,
-    max_connections_per_ip = 5
-}
-```
-
-### Strict Protection
-```toml
-rate_limit = {
-    enabled = true,
-    requests_per_second = 2.0,
-    burst_size = 5,
-    max_connections_per_ip = 2,
-    response_code = 503
-}
-```
-
-## Monitoring
-
-Check statistics:
-```bash
-curl http://localhost:8080/status | jq '.sinks[0].details.rate_limit'
-```
-
-## Testing
-
-```bash
-# Test rate limits
-for i in {1..20}; do
-    curl -s -o /dev/null -w "%{http_code}\n" http://localhost:8080/status
-done
-```
-

-# Router Mode Guide
-
-Router mode enables multiple pipelines to share HTTP ports through path-based routing.
-
-## Overview
-
-**Standard mode**: Each pipeline needs its own port
-- Pipeline 1: `http://localhost:8080/stream`
-- Pipeline 2: `http://localhost:8081/stream`
-
-**Router mode**: Pipelines share ports via paths
-- Pipeline 1: `http://localhost:8080/app/stream`
-- Pipeline 2: `http://localhost:8080/database/stream`
-- Global status: `http://localhost:8080/status`
-
-## Enabling Router Mode
-
-```bash
-logwisp --router --config /etc/logwisp/multi-pipeline.toml
-```
-
-## Configuration
-
-```toml
-# All pipelines can use the same port
-[[pipelines]]
-name = "app"
-[[pipelines.sources]]
-type = "directory"
-options = { path = "/var/log/app", pattern = "*.log" }
-[[pipelines.sinks]]
-type = "http"
-options = { port = 8080 }  # Same port OK
-
-[[pipelines]]
-name = "database"
-[[pipelines.sources]]
-type = "directory"
-options = { path = "/var/log/postgresql", pattern = "*.log" }
-[[pipelines.sinks]]
-type = "http"
-options = { port = 8080 }  # Shared port
-```
-
-## Path Structure
-
-Paths are prefixed with pipeline name:
-
-| Pipeline | Config Path | Router Path |
-|----------|-------------|-------------|
-| `app` | `/stream` | `/app/stream` |
-| `app` | `/status` | `/app/status` |
-| `database` | `/stream` | `/database/stream` |
-
-### Custom Paths
-
-```toml
-[[pipelines.sinks]]
-type = "http"
-options = {
-    stream_path = "/logs",    # Becomes /app/logs
-    status_path = "/health"   # Becomes /app/health
-}
-```
-
-## Endpoints
-
-### Pipeline Endpoints
-```bash
-# SSE stream
-curl -N http://localhost:8080/app/stream
-
-# Pipeline status
-curl http://localhost:8080/database/status
-```
-
-### Global Status
-```bash
-curl http://localhost:8080/status
-```
-
-Returns:
-```json
-{
-  "service": "LogWisp Router",
-  "pipelines": {
-    "app": { /* stats */ },
-    "database": { /* stats */ }
-  },
-  "total_pipelines": 2
-}
-```
-
-## Use Cases
-
-### Microservices

-2. **No TCP Routing**: TCP remains on separate ports
-3. **Path Conflicts**: Pipeline names must be unique

+  -t, --type <type>        Auth type: "basic", "scram", or "token"
+  -b, --basic              Generate basic auth credentials (HTTP/HTTPS)
+  -s, --scram              Generate SCRAM credentials (TCP)
+  -k, --token              Generate random bearer token
+  -l, --length <bytes>     Token length in bytes (default: 32)
+
+Examples:
+Examples:
+  # Generate basic auth hash for HTTP/HTTPS (with TLS)
+  logwisp auth -u admin -b
+  logwisp auth --user=admin --basic
+  
+  # Generate SCRAM credentials for TCP (without TLS)  
+  logwisp auth -u tcpuser -s
+  logwisp auth --user=tcpuser --type=scram
+  
+  # Generate 64-byte bearer token
+  logwisp auth -k -l 64
+  logwisp auth --token --length=64
+  
+  # Convert existing basic auth to SCRAM (HTTPS to TCP conversion)
+  logwisp auth -u admin -m --phc='$argon2id$v=19$m=65536...' --password='secret'
+
+Output:
+  The command outputs configuration snippets ready to paste into logwisp.toml
+  and the raw credential values for external auth files.
+
+Security Notes:
+  - Basic auth and tokens require TLS encryption for HTTP connections
+  - SCRAM provides authentication but NOT encryption for TCP connections
+  - Use strong passwords (12+ characters with mixed case, numbers, symbols)
+  - Store credentials securely and never commit them to version control

+### Usage:
+
+- Copy logwisp executable to the test folder (to compile, in logwisp top directory: `make build`).
+
+- Run the test script for each scenario.
+
+### Notes:
+
+- The tests create configuration files and log files. Most tests set logging at debug level and don't clean up their temp files that are created in the current execution directory.
+
+- Some tests may need to be run on different hosts (containers can be used).
