I ran into the same confusion myself at one point. Remember that the values
on the RRD graph are 5 minute averaged values. So if one minute there are 2
jobs running and the next there are 3, the 2-minute average is 2.5. The
values do actually make sense when you look at the average value.

We recently rolled out a sun grid engine platform and I'm now trying to
gather performance/usage information from it (if someone already has a
collection of scripts this would also help me immensely).
I've written a perl script that passes job queue information to hobbit
which outputs in the following format:
Running jobs : 7
Queued jobs : 0
Xfering jobs : 0
Errorstate jobs : 0
This should be ideal for ncv and I have therefore added ginfo=ncv to
TEST2RRD in hobbitserver.cfg as well as
NCV_qinfo="Runningjobs:GAUGE,Queuedjobs:GAUGE,Xferingjobs:GAUGE,Errorstatejobs:GAUGE"
on its own line because this is fluctuating data and not a counter.
The graph definition looks like this:
[qinfo]

As you can see from the attached graph there are some rather strange
results coming out and the rrd file contains values such as 3.9/4.8 when
you really can't have .x of a job and the output from the script only ever
shows whole numbers as it should.
Thanks for any help with what's going wrong.
