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.

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">We recently rolled out a sun grid engine platform and I'm
now trying to gather performance/usage information from it (if someone already

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I've written a perl script that passes job queue
information to hobbit which outputs in the following format:</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">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.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">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.</span></font></p>
