I have a little headless server and often it seems to be up to something -disk activity/network etc and when I ssh on it all goes quiet. Is there any very low level jittered logging I can set running to look at this and reduce my paranoia levels.
Nagios has lots of helper applications to do lots of monitoring of a system, but it might not be good enough for you.
I use Nagios for basic host health monitoring and MRTG with some custom scripts to graph "stuff".
However while that'll give you trends, it might not catch a program waking up from cron or some other sleep that does "stuff" for just long enough for you to notice and then exit before you get a chance to find out :)
I'd have a look at your crontabs... Gordon -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
