I've had to reply to myself as hobbit mail isn't getting through to me for some reason.

Gary or others do you know how I can get it to chart the exact vale that comes in then. It's a bit silly having a graph of 4.8 jobs etc. Also 4.5 is the average of 4 and 5 so it doesn't make much sense anyway, Also it's the data at the bottom of the graph that is really odd - queue max = 1.5m, running average 445.0m?

Not sure where that data is coming from?

Thanks,

Craig

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,Errorsta tejobs:GAUGE" on its own line because this is fluctuating data and not a counter.

The graph definition looks like this:

[qinfo]

    TITLE Q Info

    YAXIS Jobs

    DEF:running=qinfo.rrd:Runningjobs:AVERAGE

    DEF:queued=qinfo.rrd:Queuedjobs:AVERAGE

    DEF:xfering=qinfo.rrd:Xferingjobs:AVERAGE

    DEF:errorstate=qinfo.rrd:Errorstatejobs:AVERAGE

    LINE2:running#0000FF:Running Jobs

    LINE2:queued#00CC33:Queued Jobs

    LINE2:xfering#FF0000:Xfering Jobs

    LINE2:errorstate#FFFF00:Errorstate Jobs

    GPRINT:errorstate:MIN: \: %5.1lf%s (min)

    GPRINT:errorstate:AVERAGE: \: %5.1lf%s (avg)\n

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.
