Cron Jobs in the Green Data Center

Yesterday I wrote a script to monitor a UPS (running apcupdsd) server using Nagios. Today I'm looking at some of the results of the performance data. It seems that the hourly cron jobs on my server actually cause some power usage. I'll have to think over how often it's actually necessary to run those scripts given it's sucking a noticable bit of juice. Check out the graph (produced by PNP for Nagios)
