[TriLUG] "Light" monitoring

[John Vaughters]

+1 on Monit, simple and light weight. However, for even more basic information on really skinny embedded systems, consider "uptime" for cpu load and "free" for memory usage. You can easily script that and send it to another computer for analysis. 

To answer your question simply on the multi-cpu's, it is 1.00 per processor. So a quad cpu would be maxed at 4.00. Having said that, it really is not that simple, because it depends on the thread distribution across processors. Meaning it is possible for a single thread to wipe out a single core and that process may suffer. I would recommend that you start logging the cpu load and see if you can find a correlation to failure based on uptime output. BTW - uptime is the same load as top. 

Good Luck!

Forgot to mention; there are two versions of monit - the free one and the paid one.  We use the free one - http://mmonit.com/monit/

Thanks,
