# Monitor health and logs

> Local health checks, Prometheus metrics, portal status and logs.

## Health checks

* **Local health check:** `GET /healthz` on port 8080 returns `200 OK` when the Collector is running.
* **Metrics:** `GET /metrics` on the same port, in Prometheus text format.
* **In the portal:** the **Collectors** page shows each Collector's status, last heartbeat, version and host operating system. If a Collector stops reporting, the portal marks it offline, and every device behind it shows **Collector offline** instead of a stale status.
