Hey jddias,
Great thought on that one, looks like at least one of the LUNs I have reporting over is in the same situation, however I have one with > 1 year remaining that is well below on allocation. I added the screens from it.
This one has me stumped, on the datastore I can find nothing even remotely wrong. I've shifted to 5.7.1 build 1166139 from 5.6 now (vCenter and vCOPS rebuild that was planned) and I'm tweaking the policy settings at the moment, but still have odd datastore issues. I have managed to rid myself of most of the datastore alerts but ironically I've switched to usable and adjusted for HA now. Haha, I can't get any consistency with these datastore alerts. This LUN I added screens of I literally can't find a single metric off or askew, and at 184GB out of 1TB provisioned with only 82GB used, capacity is the last thing that should be "critical".
Outside of datastores though everything else appears to report excellently and as I expected I've identified a few CPU over-allocations (recommendations I made prior to even opening vCOPS, but it's nice to have easy exacts on it). Hopefully one of us finds out what's causing this one.
