Access path usage statistics
Data drive usage statistics
Data drive access rates

Performance Monitor data graphs

You can view both the short-range and long-range statistics on data graphs. All statistics can be
viewed in short range (for the storing period corresponding to the sampling interval setting).
Usage statistics about storage system resources, which are monitored in both ranges, can be
viewed in both short range and long range. When viewing usage statistics about resources, you
can specify the range to view and which part of the storing period to display on lists and graphics.
A few storage system usage statistics are not available for long-range monitoring.

Export Tool for Performance Monitor

data in a .csv file for analysis, for example, using spreadsheet software or database software.
You can also use Export Tool to save and accumulate data over extended periods of time for
long-term analysis and future reference.

Performance monitoring switch
When the performance monitoring switch is set to disabled, short-range monitoring data is
not collected.
Changing the SVP time setting
If the SVP time setting is changed while the monitoring switch is enabled, the following
monitoring errors can occur:

◦
No monitoring data is collected.
If you have changed the SVP time setting, disable the monitoring switch, and then re-enable
the monitoring switch. Next, obtain the monitoring data. For details about the monitoring
switch, see
