I am working to get alerting setup for OCUM 6.4RC1 and have noticed an annoying issue.
If I have a volume (we'll call it testvol) and it is at 89% and goes to 90%+, it alerts as you would expect. As well as if it goes from 94% to 95%+. The issue comes when going the other way. We have some very large volumes (20-40TB) that sit between 90-95% full all the time due to file rotation. We do not want to waste a ton of space by move them below 90%. The issue is that if the volume is at say 96%, and we move it down to 94%, we get another alert. This causes additional incident tickets to be generated and we waste a bunch of time closing useless tickets. Is there a way to get OCUM 6.x to act like previous versions of DFM in that it will only re-alert once it goes below a threshhold? Basically, if it is at 96% and we lower it to 94% I don't want another alert. I only want the alert if we add space to drop it to say 88%, and then it goes over 90%.
UPDATE / CLARIFICATION:
Hopefully this helps everyone to understand.
1) VolumeA goes from 89 to 90%
Triggers the 90% threshold and creates alert
2) VolumeA goes from 94 to 95%
Triggers the 90% obsolete alert
Triggers the 95% threshold and creates alert
3) We add space (or a snapshot falls off) and the volume shrinks a little
4) VolumeA goes from 95 to 94%.
Triggers 95% threshold obsolete alert
Triggers the 90% threshold and create alert
My issue is that in #4, it should not trigger another 90% alert. It should only do that if it drops BELOW 90% and then moves back over 90%.
UPDATE #2 - This is what we will see when a volume goes over 90, then over 95, and then back down to over 90 but <95.
