There are a few errors in your rrd definitions (some misplaced "IW" and "TW"), this setup will work to get the totals into the same graph.

A problem came up which required us to monitor the total number of apache servers running on our webservers, and I solved it by adding adding a CDEF to apache1 hobbitgraph.cfg definition. The attached patch uses sum of the idle & busy workers data values to create a third value, total workers, for hobbit to graph. It also allowed me to use data I was already collecting with my apache tests instead of creating a new test or addon script, which is always good in my mind.

Since it did the trick and we were able to monitor httpd more closely, I thought I'd throw the patch out to the list for others to use, if they needed something like this. If so, I hope it helps you.
