In my experience (and, I think, logically), lightweight packages are likely to require more labor to get the results that you want except for the rare occasion when the author's goals and yours coincide. Nagios is actually quite light weight. I don't like it much, but I use it extensively. Getting things like simple graphs out of it is rather difficult exactly because it is a light weight package.
