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.
- Open
C:\Program Files\Cisco\Cisco NAC Agent\NACAgentCFG.xml
- Add/modify the LogFileSize attribute to 0 (zero) as shown below:
<?xml version="1.0" ?>
<cfg>
<DiscoveryHost></DiscoveryHost>
<LogFileSize>0</LogFileSize><!-- default 5 -->
</cfg>
- Reboot
- 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′.

Many robots and spiders that are used by search engines also identify themselves by their User-Agent, if you see this activity in your logs you can often learn more about it at:
