Do you have to SSH to each and leave a window open just to put uptime in a loop to see what it’s doing? Do you have to install something like Webmin and setup a monitoring cluster? Or even setup email reports in cron to get the output of the commands? Not really, no. Remote load and usage monitoring is built-in to Mac OS X."
