Xperf utility | HP Cluster Test Software manual

The xperf utility

The xperf utility is a dynamic graph that displays performance on a number of measurements for a single node. It is started by clicking on a node icon on the Performance Monitor display.

Statistics for each measurement are shown real-time in a color-coded histogram. To see the meaning of the color-coding for an item, click on the toolbar for that measurement. For example, to see the color key for an Ethernet connection histogram, select Ethernet from the xperf toolbar.
