You do not say, so I am stabbing in the dark here about what OS this is. In XP you can set the event log size to whatever size you want and tell the log to “overwrite as necessary”. This way the log never “fills up” but continues to overwrite and keeps it at a specific size. There are other options in the properties of the event log as well. Of course you may be asking how to exclude this report altogether from being logged. It would help to know which it is you want to do. If this is not a Windows OS please specify. Including the details always helps you get the best answer. Thanks.
