Seems that Orion doesn't like the clock being adjusted. All my graphs had a zillion percent peak at 03:00 Sunday morning. Any fix for this? Guess the polling engine gets one hour of data in one polling due to the daylight saving adjustment.
I see this is an old posting, but looks like its still an issue. Our statistics show double for the 1 hr overlap (time rolled back 1hr - and stats re-collected and added). Huge spike as this is also backup window for large backups. Management is asking if i can correct this anomoly for our major interfaces.
For anyone who finds this in their searches, Solarwinds has JUST addressed it as part of the SAM 6.1 hotfix #1. A new version of the jobengine will (somehow - i haven't dug into it yet) allow for DST changes every year.
I'm glad Solarwinds finally addressed this issue!
