The Performance Monitor displays real-time performance statistics for logical drives, physical drives, and Fibre
Channel or iSCSI data ports. The vertical scale adjusts dynamically to accommodate the statistical data.
Because it reports performance in real-time, to see data in the monitor, there must be I/O data activity taking
place between the Vess R2600 subsystem and the Host.

1. Click the Administration tab.
