Web Monitor

The web monitor is a read-only inspection service built on top of Reader. It provides:

a browser UI for snapshots and key inspection,
and lists all snapshots and current pointer, with the ability to switch between tracking the current snapshot or a fixed snapshot ID.

Start via CLI

cobble-cli web-monitor --config ./config.yaml --bind 127.0.0.1:8080

Then open http://127.0.0.1:8080/.

Embed in Rust

use cobble_web_monitor::{MonitorConfig, MonitorConfigSource, MonitorServer};

let mut server = MonitorServer::new(MonitorConfig {
    source: MonitorConfigSource::ConfigPath("./config.yaml".to_string()),
    bind_addr: "127.0.0.1:8080".to_string(),
    global_snapshot_id: None, // None = follow current global snapshot
    ..MonitorConfig::default()
})?;

let handle = server.serve()?;
println!("monitor at {}", handle.base_url());

UI Build Notes

cobble-web-monitor embeds frontend assets during build. For backend-only builds:

COBBLE_WEB_MONITOR_SKIP_UI_BUILD=1 cargo build -p cobble-web-monitor

In this mode APIs still work; UI serves a fallback page.
