DFM is not picking all the events from Filer

I have recently noticed that not all the events are picked and logged by DFM from one to more filers. E.g in messages file I can see a volume went offline this morning but it was not picked up by DFM so there was no alert generated. Any idea guys?

Following is from messages file and attached is the screen shot of DFM Events for this filer

Re: DFM is not picking all the events from Filer

DFM/UM should have detected and logged an event for an offline volume.

I recommend that you open a support case to determine the cause of the monitoring failure.

Troubleshooting this will require the following - it would be good to have it ready when you open the case:

1) "dfm report view events"  CLI output

2) "dfm report view events-history" CLI output

3) DFMDC

4) "dfm host diag CONTROLLER" CLI output to the affected controller

DFM will not log volume autosize events unless you have followed the steps in this KB:

How to configure DFM Alerts for Volume Autosize, Maxdirsize Reach, or Snapshot Autodeletion

Since I notice you are looking at the legacy OM UI I want to point out that all versions of DFM prior to 5.0 will go end of support as of 12/01/2013:

Re: DFM is not picking all the events from Filer

HI,

Can you paste the "dfm host diag <filer ip>" output here?

Also can you check the dfmmonitor log for errors "/opt/NTAPdfm/log/dfmmonitor.log".

Thanks,
