Security Log Monitoring

Hello once again..

I recently created some monitors for the event log monitoring on a bunch of windows 2000 servers. These event ID's were from the Security Logs..

Somehow these monitors are not sending out any emails.. I bet I missed something.. Below are the details on what I did..

1) Created a timer Reset monitor for the event ID 123. monitor target - windows server 2000 and parent monitor security.
Event Log - Security.  Event Expression-- Event ID equals 123. Auto Reset timer -5 mins

2) Created a group and added 2 windows 2000 servers.  Disabled the monitor and created an override to be enabled for this group.

3) Created notification group. Added recepient,  group and windows 2000 server for the class.

4) Logged on to the server and checked that the new MP created has been downloaded to the local server.

5) Created the event id 123 on the security logs of the server.. no alert generated.. no email received..

Any ideas as where I went wrong?

Little stuck on step 2, have you disabled the whole monitor?

Yes. disabled the whole monitor. But enabled it by creating an override just for the group which I had created. .. Makes sense?

OK.. Simons question did make me think on the disabled monitor. What I had done was that I wanted this event to be monitored for only a bunch of servers. I created a group for those servers. I disabled the monitor and created an override just for that group where the override settings were "True". Well, I enabled the monitor for all the groups and deleted the override.. This worked. But I still wonder that why if I disable a monitor and create an override for only a group, that would not work.. Thanks all for all your help so far..

This probably falls under override precedence.  You might try clicking the "Enforce" box for your Rule-Enable override.

Thanks Brian. So you mean to say, that I disable the alert, and then create and override where I enable it for a group and check the enforce rule? Will try this and see if it works.. thx

I think you understand my meaning... You create a override to disable the rule/monitor for all classes of the target, then you create an override to enable the rule/monitor for a group or specific instance.  If this doesn't work, then "enforcing" the override to enable will make sure it works.
