# Monitoring

> Server health, metrics history, logs and the audit log.

Source: https://quasar.achaverot.fr/docs/server/monitoring/

## Dashboard

The dashboard's home page shows:

- **Server health**: live CPU, memory and disk usage.
- **History**: CPU, memory and disk over the last 24 hours or 7 days.
- **Applications**: every application with its status.
- **System containers**: Traefik, the socket proxy and the dashboard itself. Click one for its resources and live logs; the dashboard's own log is described in [dashboard log](/server/dashboard-log/).

Metrics are sampled in the background and kept for 7 days.

## System page

**System** describes the server itself:

- **Hardware**: processor, memory and disk capacity.
- **Environment**: operating system, Docker and Traefik versions. See [updating Traefik](/getting-started/updating/#updating-traefik).
- **TLS certificates**, **Docker storage**, **Volumes**, **Application storage** and **Backups**, covered in their own pages.

## Logs

**Logs** in the navigation searches the stored output of every application. See [searching past logs](/applications/logs-history/#searching-past-logs).

## Audit log

**Audit** lists who did what, when, and from where: deployments, setting changes, file edits, sign-ins, station actions…

- Entries can't be edited or deleted.
- Use the search box to filter them. The number of matching entries is shown above the list.
- Entries come 50 at a time, newest first. Use the pager under the list, or type a page number into the current page's box.
- Actions triggered by a webhook or an API token are recorded under that name.
