We have situation where we are collecting a lot of rrd data for a specific
test case (will be 16 data points). We'd like the ability to create two
different graphs off of one rrd file (and one column on the hobbit page). We
have a test called gt3_data that gets fed data from a script on a remote box
via the bb command. This scripts sends up 8 different data values to be
stored in the the gt3_data rrd. Currently we are graphing all the data
points on one graph, but it is really ugly. We'd like to split it into two
graphs, but we can't seem to find a way to tell hobbit to make two graphs
based off of one column from the webpage. It doesn't make sense in our case
to split the test into two different tests, but it does make sense to split
the data into two graphs. Does anyone know if what this is possible?



No, it's not possible with the current code.

It ought to be, I agree. But the whole handling of which graphs go where needs some major work; the current setup was adopted from Big
Brother/LARRD and is not very flexible.


I thought you could do it via several calls to hobbitgraph? For example I have a host that has many disk partitions. If I don't want to see them all on a single graph, I can select just the first partition via the "first" and "count" options:
https://www.myhost.com/hobbit-cgi/hobbitgraph.sh?host=myhost&service=disk&graph_width=576&graph_height=120&first=1&count=1&disp=my%2dhost
This gives me a graph with only that data element.
I can get a graph of only the 2nd via first=2&count=1, or elements 5-8, first=5&count=3.

Not the optimal way to do it, but it should work for creating a graph external to Hobbit, which won't have it built in as its own column the way you want, but you could always make calls into hobbitgraph from another html page.
