I'm not to sure on how to clear my log files in my CCM 5. We have a 5.1 CCM in our lab and the logs keep growing, I was wondering if there was a way to purge or delete the logs to reduce the size on the hard drive.
To delete log files, you can use remote broswer available in RTMT under Log Central. Please check http://www.cisco.com/en/US/customer/products/sw/voicesw/ps556/products_administration_guide_chapter09186a00806ad5aa.html#wp1101165
Also, the default behaviour of traces is to overwrite the old files. Therefore you should not run out of space. Also, incase you are, then change the trace configuration on the CallManager to use less number of files.These changes are made under trace configuration for each service under CCM Servicibility Page
