LogWisp

# LogWisp 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. ## Features ### Core Capabilities - **Pipeline Architecture**: Independent processing pipelines with source → filter → format → sink flow. - **Multiple Input Sources**: Directory monitoring, stdin, HTTP, TCP. - **Flexible Output Sinks**: Console, file, HTTP SSE, TCP streaming, HTTP/TCP forwarding. - **Real-time Processing**: Sub-millisecond latency with configurable buffering. - **Hot Configuration Reload**: Update pipelines without service restart. ### Data Processing - **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 - **Authentication**: Basic, token, and mTLS support for HTTPS, and SCRAM for TCP. - **TLS Encryption**: TLS 1.2/1.3 support for HTTP connections. - **Access Control**: IP whitelisting/blacklisting, connection limits. - **Automatic Reconnection**: Resilient client connections with exponential backoff. - **File Rotation**: Size-based rotation with retention policies. ### Operational Features - **Status Monitoring**: Real-time statistics and health endpoints. - **Signal Handling**: Graceful shutdown and configuration reload via signals. - **Background Mode**: Daemon operation with proper signal handling. - **Quiet Mode**: Silent operation for automated deployments. ## Documentation Available in `doc/` directory. - [Installation Guide](installation.md) - Platform setup and service configuration - [Architecture Overview](architecture.md) - System design and component interaction - [Configuration Reference](configuration.md) - TOML structure and configuration methods - [Input Sources](sources.md) - Available source types and configurations - [Output Sinks](sinks.md) - Sink types and output options - [Filters](filters.md) - Pattern-based log filtering - [Formatters](formatters.md) - Log formatting and transformation - [Authentication](authentication.md) - Security configurations and auth methods - [Networking](networking.md) - TLS, rate limiting, and network features - [Command Line Interface](cli.md) - CLI flags and subcommands - [Operations Guide](operations.md) - Running and maintaining LogWisp ## Quick Start Install LogWisp and create a basic configuration: ```toml [[pipelines]] name = "default" [[pipelines.sources]] type = "directory" [pipelines.sources.directory] path = "./" pattern = "*.log" [[pipelines.sinks]] type = "console" [pipelines.sinks.console] target = "stdout" ``` Run with: `logwisp -c config.toml` ## System Requirements - **Operating Systems**: Linux (kernel 6.10+), FreeBSD (14.0+) - **Architecture**: amd64 - **Go Version**: 1.25+ (for building from source) ## License BSD 3-Clause License
