Yeah, when you wrote that solution like that I was afraid that's what you'd

What you can do is create a subdirectory 'overview1' in the data/rrd directory. In that directory you can then create symlinks for the data you want to graph.
I use this to graph the memory usage of AIX lpars running on the same hardware box. So I create a subdirectory 'data/rrd/pSerie1' and in the subdirectory I create symlinks for each server running on that pSerie:
vmstat-server1.rrd -> ../server1/vmstat.rrd
vmstat-server2.rrd -> ../server2/vmstat.rrd
vmstat-server3.rrd -> ../server3/vmstat.rrd
I then added a section to hobbit-graph.cfg to process all 'vmstat-(.*).rrd' files and stack the data on top of each other:
[vmstat-avm-total]
FNPATTERN vmstat-(.+).rrd
TITLE Accessed Virtual Memory (Stacked)
YAXIS Size kB
-b 1024
DEF:avmt at RRDIDX@=@RRDFN@:mem_avm:AVERAGE
CDEF:avm at RRDIDX@=avmt at RRDIDX@,4048,*
LINE1:avm at RRDIDX@#@COLOR@:@RRDPARAM@:STACK
GPRINT:avm at RRDIDX@:LAST:AVM \: %5.1lf%s (cur)
GPRINT:avm at RRDIDX@:MAX: \: %5.1lf%s (max)
GPRINT:avm at RRDIDX@:MIN: \: %5.1lf%s (min)
GPRINT:avm at RRDIDX@:AVERAGE: \: %5.1lf%s (avg)\n
The result is a stacked graph with 1 line per server.
For the graph, the url is something like
hobbitgraph.sh?host=pSerie1&service=vmstat-avm-total&action=menu
I hope this info can help you.
