Three of the components of my BES application monitor just stopped working out of the blue with " Testing on node HRKBES: failed with 'Unknown' status".
We tried restarting the SNMPD on the BES server but this did not fix the issue. Thoughts?
Could you check if the same OID returns you values when checking manually? (You can check it with Universal device poller).
Was anything installed lately on the BES server or was other server was added as DR solution?
In my case, when we installed another server that .20 at the end of the OID turned to .21 for some reason.
