Disable Cisco NAC Agent logging

I recently had to use a Windows computer with Cisco NAC installed, and found that there was a lot of disk activity for logging.

These files would grow to approximately 5MB before rotation.

C:\Documents and Settings\All Users\Application Data\Cisco\Cisco NAC Agent\logs\NACAgentLogCurrent.log
C:\Documents and Settings\All Users\Application Data\Cisco\Cisco NAC Agent\logs\NACAgentLogOld.log

To reduce this overhead (when no problems exist), the config file is exposed in XML.

  1. Open C:\Program Files\Cisco\Cisco NAC Agent\NACAgentCFG.xml
  2. Add/modify the LogFileSize attribute to 0 (zero) as shown below:

    <?xml version="1.0" ?>
    <cfg>
    <DiscoveryHost></DiscoveryHost>
    <LogFileSize>0</LogFileSize><!-- default 5 -->
    </cfg>
  3. Reboot
  4. Remove the old .log files

NOTE: if you ever have networking issues and require support, you will need to restore the default value to ‘5’.
