# Heartbeat Format Examples:
#
# Comment format (SSE):
# : heartbeat 2025-01-07T10:30:00Z clients=5 uptime=3600s
#
# JSON format (SSE):
# event: heartbeat
# data: {"type":"heartbeat","timestamp":"2025-01-07T10:30:00Z","active_clients":5,"uptime_seconds":3600}
#
# TCP always uses JSON format with newline delimiter

# Usage Examples:
#
# 1. Standard mode (each stream on its own port):
#    ./logwisp
#    - App logs: http://localhost:8080/stream
#    - System logs: https://localhost:8443/logs (with auth)
#    - Debug logs: http://localhost:8082/stream
#    - Archive logs: tcp://localhost:9091
#
# 2. Router mode (shared port with path routing):
#    ./logwisp --router
#    - App logs: http://localhost:8080/app/stream
#    - System logs: http://localhost:8080/system/logs
#    - Debug logs: http://localhost:8080/debug/stream
#    - Global status: http://localhost:8080/status
#
# 3. Override config file:
#    ./logwisp --config /etc/logwisp/production.toml
#
# 4. Environment variables:
#    LOGWISP_STREAMS_0_MONITOR_CHECK_INTERVAL_MS=50
#    LOGWISP_STREAMS_0_HTTPSERVER_PORT=8090
#
# 5. Show version:
#    ./logwisp --version
