Op manager is supposed to collect performance monitors ( such as disk & memory utilizations datas - available partition datas for each partitions) automatically after we added the performance monitors.

After we click test monitor button, it wasnt collecting any data for any performance monitor.

Then it started to collect datas but there's 1 thing we set the monitor interval setting 1 minute for cpu 1 minute for memory 30 minutes for disk but it randomly collects datas

For example ;

We need your help on this ? How can cause this problem ?

Thanks in advance.
