Hi,
I have a server running Centos 5.2 and am implementing a GIS mapserver app. I have some sample logs from another implementation that give me an idea of bandwidth requirements but I would like to check the cpu load. I can not be at the server during the test and am interested in knowing if there is logging of cpu load available. Anyone have experience with this? Recommendations?

install sysstat and use sar, by default it logs data once every 10 minutes I believe(adjustable via configuration).

If you have the sysstat package installed, sar will show samples from 10 minute intervals.

I use munin for almost all my server monitoring. It is quite lightweight and you can easily configure it to only record basic CPU info or more detail as required. It is available in the EPEL repository.

Another vote for sysstat/sar. It has been around forever and this is it's purpose. It also monitors all sorts of other parameters as well.

Does anyone know of a useful guide to help me do the analysis of sysstat/sar reports?

Start with the man page, it's loaded with stuff. Make sure to check the "See Also" section. The sysstat homepage is here: http://pagesperso-orange.fr/sebastien.godard/

Check-out "ksar" which does a good job for plotting SAR data.

I've been using MRTG for ages to monitor cpu load and happily recommend it for all manner of monitoring (not just routers 8^). MRTG can be found at: http://oss.oetiker.ch/mrtg/index.en.html
...and the program to pass cpu load to mrtg can be found at: http://oss.oetiker.ch/mrtg/pub/contrib/linux_loadavg_mrtg.tar.gz
