Viewing volume and LUN latency charts to verify performance guarantee
Suggest changes
PDFs
You can view the volumes and LUNs that you have subscribed to the “Performance Guarantee” program to verify that latency has not exceeded the level you have been guaranteed.
About this task
The latency performance guarantee is a millisecond per operation value that should not be exceeded. It is based on an hourly average, not on the default five minute performance collection period.
Steps
-
In the Performance Volumes or Performance LUNs inventory page, select the volume or LUN that you are interested in.
-
In the Performance Explorer page for your selected volume or LUN, choose Hourly Average from the View statistics in selector.
The horizontal line in the Latency chart will show a smoother line as the five-minute collections are replaced with the hourly average.
-
If you have other volumes on the same aggregate that are under the performance guarantee, you can add those volumes to view their latency value in the same chart.
