Since the Performance Monitor is a real-time display, it does not accumulate
information and there is no clear or save function.
To save performance statistics for analysis or troubleshooting, save a Service
Report, open the report, and look under Statistic Info. See “Saving a Service
Report” on page 79.
Monitoring PSU Wattage
The PSU Wattage Monitor displays real-time performance statistics for logical
drives, the input power of all enclosures and the input power of an individual. 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 VTrak subsystem and the
Host.
To monitor performance and power use:
1. Click the Administration tab.
2. Click the PSU Wattage Monitor icon.
3. Under Logical Drive, choose the metric you want to see from the
Measurement dropdown menu.
