As we know that, OUCM event monitoring is done every 15 minutes. My question is - Does this eventtrap checks the schedule of the snapmirror only once and then calculates the lag as per the last transfer time.
one of my snapmirror relationship schedule is : every 24 hours, basically @00:20 hours every day. Now, My OUCM event also co-incides at 00:20 hrs due to 15 minute internal, for ex-00:05,20,35 and so on.
In this case - OCUM sent an alert next day @12:35pm next day, that the lag is 1 Day and 12 hours past. This is understood, b'cos by default, WARNING threshold is to 150 % of lag time, which comes to 150% of 24hrs = 36 Hours or 1 Day 12 hours.
Why did OUCM did not check that that the snapmiror was updated @next OCUM event and therefore, delay should have been only 12 hours at 12:35PM next day
