Our new 8.3 cluster is in production, finished migrating the last vservers to it last weekend, and suddenly we're getting ~6 alerts a day from an OPM server set up by a co-worker who's left the organization. I confess I've barely looked at the thing until now.
Whenever I go to investigate the details of the latest "incident" I find that it's not a problem, i.e. latency on a volume "jumped" from <1ms to ~5ms. Looks like the application is looking for deviation from a dynamically determined baseline and I'm not seeing any option for tweaking parameters or limits.
Six false alarms a day makes this effectively useless.
Anybody else using this app? Got any tips on making it useful?

If this is opm 6.x, it's using a standard deviation model and not a fixed threshold. So it's very chatty until new loads have burned in for a reasonable amount of time (a few weeks). The alerts cam be disabled but I believe that's global.

Which version are you using? 1.0, 1.1 or 2.0 (which just went GA)?
