The user wants to monitor the snapmirror information, especially if the snapmirror lag time is breached. Is there a must to use DRM to monitor, or is there other ways to create the alert?

That is my understanding.
I have created a bat file which I run from my pc which passes the command
rsh %FILER01% -l %RSHPERM% "snapmirror status filer:volume" >>c:\Logfiles\%COMPUTERNAME%_SnapMirrorList.txt
and just repeat for every snapmirror.
We also use MOM and have used the NetApp SDK to use VBS to poll the snapmirrors witch have 15 minute updates.
Hope this helps

Snapmirror status monitoring requires BCO or Protection Manager license.
You can use the dfm run command to run commands on filers.And get the snapmirror status and use script plugin to generate
custom events and generate alarms.

If you have any of the license mentioned, Then you can get the snapmirror lag warning and error evet for all filers monitored by dfm.
by default snapmirrorLagWarningThreshold is 1.5 days,
snapmirrorLagErrorThreshold is 2.0 days.
which can be changed.

Thanks...But how to get the alert when the lag time is over, that means the sanpmirror is not working properly. Also, is there able to get an email alert when this happen? Otherwise, the user will not know until the check on the messages.

The Protection Manager and Protection Manager DR licenses are installed, but still cannot get the snapmirror lag alarms. There were several snapmirrors having a lag time for more than 4 weeks, but didn't get the alarms. Any idea?
I have attached the screenshots.

Ops-Mgr monitoring snapmirror generates an event for the relationships like this for lag.
[root@lnx]# dfm eventtype list -C sm.lag
Event Name Severity Class
-------------------------------------------------- ------------ ------------------
snapmirror:date-ok Normal sm.lag
snapmirror:deleted Information sm.lag
snapmirror:nearly-out-of-date Warning sm.lag
snapmirror:out-of-date Error sm.lag
What you are showing is the PA threshold, I dont thing so both are same.
AFAIK That threshold is for the counter value and has nothing to do with the snapmirror lag that you have attached.
Can you try creating an alert in Ops-Mgr for this event i mentioned above and see you get the event.
