Viewing the performance graphs for volume and file system
In the Management Server console, you can view the performance of a volume and file system in an interactive graph. You can review the performance of a volume for different durations - 6 hours, 24 hours, 1 week, 1 month, 1 year, or based on live data. You can review the performance of a file system for a duration of one month or one year. In case of Windows hosts, you can review the performance of a file system for a duration of six hours, 24 hours, one week, one month, one year, or based on live data.
If a file system is mounted on a volume, then you can view the file system graphs in the volume performance graphs view. If there is no file system mounted on the volume, then only volume performance graphs are displayed.
You can view the performance graphs only for a Storage Foundation volume and if the volume belongs to a disk group.
Table: Performance graphs for a volume lists the performance graphs for a volume.

You can view these performance graphs for the hosts, for which your user group has at least Guest role explicitly assigned or inherited from a parent Organization. You can also view the graphs if your user group has at least Guest role assigned on the Server perspective.

- Expand the host and then expand to locate the volume to view its performance graph.
- Select the volume, and click the Performance tab. To change the duration, use the drop-down list.
- Click the ellipses in the file system graph to select another file system. The ellipses are displayed only if the file system is a shared file system.
