I have a use case to count the timeframe for specific outages.
E.g. volume full genereates an event with status "error". After some time it when the problem is fixed there is another message which gets to state "normal". Is this possible to use the events to calculate the time between and provide this in a report?
It is possible, but it might not be most accurate. Event is generated when the monitors run. so if the monitor has run now and after that the volume state changes to normal opsmgr generates the event only when the next monitoring cycle is run.
Re: can OnCommand report capture events from OnCommand core?
Here we want to count the time how long a performance degradion was in sum. This for each volume and rate the volumes with the highest values. Then can make a decission to look closer o that volume with performance advisor to find out the problem. Hopefully Oncommand Insight Report can help here. Otherwise we have to write our own scripts. Or using tools like splunk to combine queries for a report.
