# Health Check

> Configuration for the server health check service.

<partial content="config-env-vars">



</partial>

The health check service powers the `/server/health` endpoint, which reports the status of connected services like the database, edis, storage, and email. Results are cached and shared across requests to avoid excessive checks.

**Note**<br />


Including `redis` or `email` in `HEALTHCHECK_SERVICES` does not guarantee they are checked:

- `redis` is only checked when Redis is configured (see [`REDIS_ENABLED`](/configuration/synchronization)).
- `email` is only checked when [`EMAIL_VERIFY_SETUP`](/configuration/email) is `true`.

</callout>

Individual services also support their own health check threshold configuration. See [Database](/configuration/database), [Cache](/configuration/cache), [Files](/configuration/files), and [Security & Limits](/configuration/security-limits) for `*_HEALTHCHECK_THRESHOLD` variables.
