2.4 File System Statistics

Oracle VM Manager periodically collects vital statistics about file system utilization. Select the File System Statistics subtab of the Health tab to view the current statistics reported for each file system in use by your Oracle VM Servers. Statistics are only collected for file systems that are mounted within your Oracle VM environment for the purpose of hosting a repository.

Note that statistics collection is an asynchronous and periodic service, so the information displayed on the Health tab is not in real time, but is dependent on the file system statistics collection interval that is configured for this service. Furthermore, the historical period over which you are able to view this data is limited to the statistics collection hold time value configured for this service.

Statistics for file systems are organized by the storage where they are hosted. There are top-level nodes for File Servers, Local File Systems and Shared File Systems. You can expand these nodes in the navigation pane to list all of the storage for which file system statistics are available. Clicking on a storage node in the navigation pane updates the management pane to display the file systems available for that storage node and displays the relevant statistics.

Note

You can disable statistics collection in Oracle VM Manager from the Preferences subtab of the Reports and Resources tab. For more information about disabling statistic collection, and the implications of doing so, see Section 7.4, “Preferences”.

The toolbar at the top of the management pane provides the following options:
