From Chaos to Placidity

I wrote this script to do the following.  It logs into X number of servers you define in a configuration file, and pulls some general system info.  I find this useful if I’m trying to get a better picture of a host(s) that don’t have robust monitoring already done.

This is crude and needs some tweaking.  I recommend having an admin user account with SSH keys that has normal user + sudo access to the host.  The information that I collect doesn’t need su access so if your keys are distributed you could just execute the tool and walk away.  Here is some of the information it generates for you:

I’ll be posting a zip package soon with the script.  I haven’t done a great job of cleaning it up yet, so take it as is  If anything, it can help give you a starting point at writing your own audit scripts.
