Hi,
'Alarm Test' can be done from the Operations Manager UI also. Go to Setup > Alarms. There is a "Test" link in the alarm table at the bottom.
To verify that the events are generated for the conditions you mention, you can use 'dfm report view events <object>' .<object> can be skipped to list all events, or it can be a volume or storage system to list only the events on that object.
The log files to look at is alert.log (under <dfm-install-dir>\log folder). You should see messages like this:
Oct 25 19:34:23 [dfmeventd: INFO]: alarm 53, event 9340870, Host Down on corefiler: sending email alert to <mail-id>
Any failure in sending mail will be logged to dfmeventd.log. You should see messages like:
Nov 20 05:16:38 [dfmeventd: ERROR] alarm 11, event 1042252: failed to deliver email alert to <mail-id>
Thanks,
Raj.
