We did a SAN controller upgrade over the weekend. We had no issues there at all, but after the upgrade was done we saw view admin showing the vCenter Server service as "red". Restarting vCenter Server Service on the server resolved the issue and it went "green" about 5 minutes after the service was restarted. I came in this morning and the "red" status had returned, restarting the service brought it back to "green".
Is there an easy/good/best way to troubleshoot this? View Admin is completely useless for troubleshooting any "red" service issues. I've gone through logs, event viewer, bundles, etc and don't see anything that would tell me why View Admin thinks there is an issue. I can provision VM's, delete them, recompose, etc without issue. as far as I can tell vCenter is fine and it's making me wonder if its View Admin having the issue and not vCenter. What do you guys normally do to troubleshoot "red" statuses?
