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?

Anyone have experience with this? > Recommendations?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. http://download.fedora.redhat.com/pub/epel/4/i386/repoview/munin.html http://munin.projects.linpro.no/ -Dougal> > Dave > > -- > Canada must refuse to be entangled in any more wars fought to make the world > safe for capitalism. > > -- The Regina Manifesto, 1933 > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos >
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.

Anyone have experience with this? > Recommendations?I've been using MRTG for ages to monitor cpu load and happily recommend it for all manner of monitoring (not just routers 8^).
