Customizing the Polling Interval

A polling interval defines how often new data is collected. A new collect can be performed from once every second, to once in a day. Hitachi Disk Arrays KM for PATROL polls the managed systems to collect performance and statistics data. By default, the polling interval for this "data-collect" is set to every 2 minutes.

The more the polling interval is low, the more the collection process is time consuming

To change the polling interval for the managed system, right-click the Hitachi Device Manager icon > KM Commands > Polling Interval…

Customizing Polling Interval

In addition to the polling interval that is a global setting, i.e. it is applicable to the whole managed system, you can also manually trigger a poll at any time on individual instances to refresh parameter values. Right-click the instance icon > Refresh Parameters.
