Some appliance processes require a specific amount of disk space to complete. If disk space is not available, the processes do not start. An error message describes the problem.
You can view the current health status of the disk storage, system load, and system memory by running the following CLI command:
show health system
For example, you may need to delete files and artifacts to free disk space if there is not enough room to do a database backup, to retrieve SNMP data, or to send system notifications. It may also be necessary to free disk space before upgrading the appliance.
System tools help you manage the disk space both automatically and on demand. For details, see Automatic artifact cleanup . See On-demand cleanup using profiles .
