6.3. Confirming Data Storage Usage
To confirm data storage usage, enter the following command:
# less /var/log/pcp/pmlogger/$(hostname)/pmlogger.log
This lists all available metrics, grouped by the frequency at which they are logged. For each group it also lists the storage required to store the listed metrics, per day.
Example storage statistics
