    LEM Events stop updating Filters







      Monitoring LEM over the last two months, I have noticed LEM has twice had a database issue causing LEM not to display any events.  On both occasions, LEM syslog shows LEM receives data from devices.  Looking at the hypervisor, it does not show any alarms for the LEM VM.  I finally got LEM to display events in filters after I issued a dbrestart.  Any thoughts on how I can further troubleshoot the cause of this issue?




      Thank you,

          Can you SSH into the LEM and run a VIEWSYSINFO under the MANAGER menu and show the output?

              Following are the first couple of lines from the viewsysinfo.

              Is there something in the output of viewsysinfo that would give me an indication why Events were not displaying in the Filters even though LEM received syslog messages from the devices?  Or, when this problem started?

                  You need to set reservations for the LEM's memory and CPU, or this issue will continue to occur.  Reservations should be set equal to the currently assigned resources, in your case the 8GB of memory and 2660 CPU.


                  You may also want to enable the Template rules "Appliance Database Down" and "Solarwinds Disk Full" which would watch the LEM's own health and send an alert when stuff goes wrong.
