Timeframe for vmotion in vmware health check script

Hi

im using vmware health check script 5.. After running on client side i got 3300 vmotion performed. I want to know what is the timeframe defined in scripts for vmotion like does it look at all the logs and give all the vmotion performed since server started or for a week/month and how can i define a period. Like i want to figure out how many vmotion performed in a month..

thanks in advance for help..
