# srvmon

Real-time monitor for [Caddy](https://caddyserver.com/) 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`)

## Building

```
cargo build --release
```

## Usage

```
srvmon [OPTIONS]
```

| Option | Default | Description |
|---|---|---|
| `-d, --dir <DIR>` | `/var/log/caddy` | Log directory path |
| `-l, --lines <N>` | `8` | Number of lines per column |
| `-b, --bind <ADDR>` | `127.0.0.1` | HTTP server bind address |
| `-p, --port <PORT>` | `8080` | HTTP server port |
| `--no-tui` | | Disable terminal display |
| `--no-http` | | Disable HTTP server |

## HTTP interface

By default, srvmon serves a web UI on `http://127.0.0.1:8080` that mirrors the terminal display via Server-Sent Events. The SSE endpoint is available at `/events`.
