LMS 4.2.2 Fault discovery stalls, never complete

Question

                  Using LMS 4.2.2 on a network with approx 800 devices. Fault discovery runs for long periods without completion, previously known devices sit in learning state for long long periods. Some devices do become known but this seems random as to which ones. Faults are still reported on devices in a learning state, which means there are often many faults reported which are false. However because devices are in learning state the false positives cannot be weeded out. This problem has been occuring since LMS 4.0 so have not had Fault and event monitoring working properly for some time, however would seriously like to utilise this feature.
Would appreciate any pointers as to where to start... Mark

Answer 1

I am having the IP vs. device name issue as well. The funny thing is if you hover over the IP of the device in Fault Monitor, you can see the device name listed. I was on a conference call with Cisco recently and pointed this out. One of the reps said the faults and alerts showing IP address issue should be fixed in version 4.2.3, but I don't know if he was basing this on first-hand knowledge or was just assuming. Does anyone know if this is the case?
As for throttling alerts. I had a false positive alert from a device that I put in a custom fault group and changed the threshold on to keep them from firing. You probably have already resolved this issue, but I didn't see a resolution listed here. You would have to determine if raising a threshold for a device is adequate for your situation.
Thank you,
