I noticed when you click a disk graph, that the url indicates which partitions to display via "&first=1&count=4", would show all four disk partitions. If you change that to &first=1&count=1, it only graphs the first disk partition (usually /).
I tried the same thing with the temperature graphs and it worked, ie: http://www.myhobbitserver.com/hobbit-cgi/hobbitgraph.sh?host=somehost.com&se...
Displayed the graph for only "Ambient".
You have sharp eyes - yes, this is precisely how hobbitgraph handles cases where there are multiple graphs combined in one image. It builds a list of the available graphs, sort them by a key - for disks that is the filesystem name, for temperature it's the name of the temperature monitor - and uses the "first" and "count" settings to decide which ones from this set of data to include on the current graph.
I guess a question I would have about that is how could I set that as default, or even better, if there was some GUI way to select which values to include in the graph (maybe its part of Cacti already, I dunno).
There's currently no way of setting up a default view of a graph - apart from which graph to include in the default set, you might also want the monthly graph as the default, instead of the 48-hour graph; or you want the graph to be clipped at some maximum value by default; or ... lots of other possibilities. Plus a GUI to dynamically tune the graph in real-time.
It's something I want to improve after the 4.0 release is out. So I'll happily note your input, but postpone any implementation of it till later. Some of the stuff I want to do requires changes to the RRDtool library - Tobi Oetiker (RRDtool author) doesn't want to do these changes for RRDtool 1.0.x, so I'll probably end up including a modified RRDtool with Hobbit. And that's just too much work for 4.0.
