4. Click Enable in the Monitoring Switch field.
5. Select the collecting interval in the Sample Interval.
Specify the interval to obtain usage statistics about the storage system for short range
monitoring. This option is activated when you specify Enable for Current Status. If CUs to be
monitored are 64 or less, you can specify the value between 1 and 15 minutes by minutes,
and the default setting is 1 minute. For example, if you specify 1 minute for the gathering
interval, Performance Monitor collect statistics (such as I/O rates and transfer rates) every one
minute.
If CUs to be monitored are 65 or more, the gathering interval can be specified to the value
5, 10 or 15 minutes (in the 5 minuted interval), and default is 5 minutes. For example, if you
specify the gathering interval to 5 minutes, Performance Monitor gathers statistics (such as
I/O rate and transfer rate) every 5 minutes.
6. Click Finish.
