# Monitor disk space usage

Use the `p4 diskspace` command to monitor disk space usage. By default, this command displays the amount of free space, disk space used, and total capacity of any filesystem used by P4 Server.

If `P4AUDIT` is configured on any active server, the audit log file becomes large very quickly because it grows each time any user gets file content. Make a plan to manage the disk space. Include in your plan any retention policies for storing historical copies of the audit log files.

By default, P4 Server rejects commands when free space on the filesystems housing the `P4ROOT`, `P4JOURNAL`, `P4LOG`, or `TEMP` falls below 250 megabytes. To change this behavior, set the `filesys.P4ROOT.min` (and corresponding) configurables to your desired limits:

- `filesys.P4ROOT.min`
- `filesys.P4JOURNAL.min`
- `filesys.P4LOG.min`
- `filesys.TEMP.min`
- `filesys.depot.min`

If the user account that runs the P4 Server process is subject to disk quotas, the server observes these quotas with respect to the `filesys.*.min` configurables, regardless of how much physical free space remains on the filesystems in question. For the options you have in reconfiguring default values, see Specify values for filesys configurables.

To learn more, see Configurables in the P4 CLI Reference.
