# Health checks

Cedana can be health checked to ensure it fully supports the system and is ready to accept requests.

## Basic

To do a simple health check, ensure the daemon is running, and then run:

```sh
cedana daemon check
```

This just checks for basic checkpoint/restore capabilities on the host.

## Complete

To do a more complete health check, ensure the daemon is running, and then run:

```sh
cedana daemon check --full
```

This health checks all the installed plugins, including some optional checks. If you have installed plugins, you should see an output similar to:

```

Looks good, with 2 warning(s).

```

## Without daemon

You can also run the health check directly, without the daemon:

```sh
cedana check --full
```

Warnings are shown in yellow and are usually related to system configuration or performance. They are not critical but may affect the performance of Cedana.
