Since I installed LMS 4, the Faults panel at the top of the screen always reports 4 critical faults. When I click on the red icon to go to the Fault Monitor, I get "No faults are available" (screenshot attached).
I've looked at the code, and there could be two potential problems. One could be that the cache is stale. The fault values are cached for 60 seconds per user, but something may be preventing the update. A restart of Daemon Manager should confirm if that is the problem. If that does not fix the issue, the database may have stale data. Have you removed devices from LMS?
The quickest way is to reinitialize the DFM databases by following the instructions in https://supportforums.cisco.com/docs/DOC-8796 . However, if you want a more tactical analysis you can open a TAC service request, and they can go through the dfmEpm database to look at why these counters are wrong. The counters should be showing the total number of events, which are the atomic conditions occurring on the devices. This would not necessarily line up to the alerts seen at the top level of the Fault Monitor. However, in your case since you don't see any alerts, you shouldn't have any events.
