If I want to use this to gather cpu information, and only for a summary of all cpu's then the command to run would be: ./check_sa.pl -i -C %user -C %nice -C %system -C %iowait -C %idle --sa-log-dir=/var/log/sa --sadf-options -u Or all cpu's: ./check_sa.pl -i -C %user -C %nice -C %system -C %iowait -C %idle --sa-log-dir=/var/log/sa --sadf-options "-P ALL -u" Etc. The advantage of this is that you significantly increase the speed of the check. With just -u it is 'real 0m0.088s', and -u -P ALL it would be 'real 0m0.191s'. With -A it is 'real 0m0.356s'. When checking 3000+ servers every little bit helps :). I’d suggest adding something like –sadf-options.

I have a lot of questions about specific use cases though. I like this, and I think I’ll be using it in a test deployment. I have a lot of questions about specific use cases though.
