The Monitoring Switch area in the Monitoring Options window contains the
following items:
• Current Status
Select Enable to start obtaining statistics from the storage system (that is,
monitoring). To stop monitoring, select Disable. The default setting is
Disable.
• Gathering 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.
