7 Setting statistical storage ranges
This topic describes setting statistical storage ranges.
About statistical storage ranges
Performance Monitor collects and stores statistics for two time periods (ranges): short range and
long range. The difference between the two ranges and the statistics they target are as follows:
• Short range
If the number of CUs to be monitored is 64 or less, statistics are collected at a user-specified
interval between 1 and 15 minutes, and stored between 1 and 15 days.
If the number of CUs to be monitored is 65 or more, statistics are collected at a user-specified
intervals of 5, 10, or 15 minutes, and stored for 8 hours, 16 hours, or 1 day, respectively.
• Long range
Statistics are collected at fixed 15-minute (0, 15, 30, and 45 minutes of every hour), and
stored for 93 days (for example, 3 months).
Usage statistics about storage system resources are collected and stored in long range, in
parallel with in short range. However, some of usage statistics about resources cannot be
collected in long range.
Viewing statistics
Use the Monitor Performance window to view statistics within short and long storage ranges. All
statistics, except some information related to Auto LUN V2, can be viewed in short range (for the
storing period corresponding to the collecting interval setting). In addition, usage statistics about
storage system resources can be viewed in both short range and long range because they are
monitored in both ranges. When viewing usage statistics about resources, you can specify the
range to view and which part of the storing period to depict on lists and graphics.
Setting the storing period of statistics
To set the storing period of statistics:
1. Display the Remote Web Console main window.
2. Select Performance Monitor in Explorer, and select Performance Monitor in the tree.
The Performance Monitor window opens.
3. Click Monitor Performance in the Performance Monitor window.
The Monitor Performance window opens.
4. Select Long-Range or Short-Range in the Data Range as the periods (ranges) for collecting
and storing statistics.
