srvmon
Real-time monitor for Caddy access logs. Displays two columns:
- Latest: recent activity, grouped into consecutive runs by service
- Top: all-time request counts per service, sorted descending
Watches the log directory with inotify so updates appear instantly. Handles both plain .access.log files and rotated .access.log.gz archives. Persists state to .srvmon.state.json in the log directory to avoid re-counting on restart.
Requirements
- Linux (uses inotify)
- Caddy access logs in JSON format (
<service>.access.log)

cargo build --release
