Collecting RRD from custom script, but no graph

[Syms.MS at forces.gc.ca]

Hi, folks-

I wrote a custom data collection script to send varying data to hobbit- hobbit receives it ok, displays the status properly and populates an rrd to store the data, but then doesn't graph it.  I do get the graph name in a text hyperlink beside the magnifying glass icon, but that's it.

I've done a similar thing with hobbit on a debian box before without a problem, but now that I'm running it on an aging Redhat Advanced Server 3 box, it's giving me some trouble.

The configuration bits: I'm running rrdtool 1.0.48, gcc 2.3.3 and Hobbit 4.1.2p1.

The output line from my script:
${BB} ${BBDISP} "status ${MACHINE}.trackoswex ${COLOR} `date` 

trackoswex: ${TRACKS}

"

In hobbitlaunch.cfg, I'ved added
[trackoswex]
        ENVFILE /usr/local/hobbit/client/etc/hobbitclient.cfg
        NEEDS hobbitd
        CMD /usr/local/hobbit/server/ext/gccs/trackoswex.sh
        LOGFILE $BBSERVERLOGS/hobbitclient.log
        INTERVAL 30m

>From hobbitgraph.cfg
[trackoswex]
        TITLE OSWEX Tracks

        DEF:tr=trackoswex.rrd:tracks:AVERAGE

Any help would be appreciated!
