Auit Trail or computer removal clean up

Hi, is there any way i can handle audit Trail clean up for retired or not reported computer for last 30 days to 60 days , so that it should not remove not responding agent to keep track on that?

BESAuditTrailCleaner-3.0.10.97.exe -d bes_bfenterprise -u user -p pasword -D “08-26-2016” -S -b 100000

The AuditTrailCleaner only removes data for things that have already been deleted/removed from the console, so it will not affect computers that haven’t reported recently but are still showing as offline in the console. The ComputerRemover date settings will determine when those offline computers are removed from the console.
