How to Graph Device Statistics (DiskSuite Tool)

Use this task to display instantaneous statistical information in the form of a graph for a device.

1. Select Statistics Graphs from the Browse menu in the Metadevice Editor window to display the Statistics Graphs window.

2. Drag an object from either the Metadevice Editor window or the Disk View window to the Statistics Graphs window.

   The Statistics Graphs window will display statistics and a blank area for the graph of the object. The MetaDB object, hot spare pools, and slices are not able to graph statistics.

3. Choose the statistical information to be graphed.

   The Statistics Graphs window contains two "y-axis" (two vertical scales) of statistics. Thus, you can graph any two of the types of statistics available:

   Ops/sec - The number of disk I/O operations per second, measured in terms of reads, writes, or as a total.

   Kbytes/sec - The number of kilobytes of disk I/O, measured in terms of reads, writes, or as a total.

   Load - The disk load measured either as the percentage of time busy, or as a wait queue, which represents the average number of transactions waiting for service.

4. When done using the Statistics Graphs window, select Put Away from the All Graphs menu.

   If you do not put away a device, the Statistics Graphs window automatically includes it the next time it is opened.
