## Operating system based
<a name="_operating_system_based"></a>

There are multiple operating system commands that can be run as root or as a user with appropriate permissions. The commands enable you to get an overview of the status of the cluster and its services.

```
# pcs status --full
```

Note: Omit the `--full` for a more concise output if you do not need to view the node attributes.

Sample output:

```
