# Host Metrics

Live CPU, memory, disk, network and process metrics, plus host management (services, packages, firewall, cron, users, SSL, logs, WireGuard). Other plugins add manager cards through the `host-metrics.managers` slot (Tailscale does).

The host list's online and offline dot is core's own status check, not this plugin. A working metrics login is what turns a reachable host online.

Bundled with Termix and enabled by default.
