Hi Michael 

I have a rule limiting alerts on 18154 events inside my local_rules.xml file
  <rule id="101013" level="7" frequency="4" timeframe="1600">
        <if_matched_sid>18154</if_matched_sid>
        <match>WinEvtLog: System: ERROR(13): NPS:</match>
        <description>turn down the noise on this event</description>
   </rule>
My understanding is that this rule will generate an email (level 7) after more 
than 4 matching events, and will not send more than one alert every 1600 
seconds.

http://www.ossec.net/ossec-docs/OSSEC-book-ch4.pdf
Read the section on Understanding rules of this doc it helped me a lot to grasp 
alert filtering.

I'm still new to this.  If someone sees an error with my rule, I don't mind if 
you point out the error of my ways...
cheers

Subject: [ossec-list] Turn off rule?


Is there a way to configure the ossec agent to ignore specific windows events? 
I have an application that is mis-behaving and its creating ossec alerts for 
multiple windows events 

Rule: 18154 (level 10) -> 'Multiple Windows error events.' 

Can I configure OSSEC agent to eliminate rule 18154?
