Usually the magnifying glass link with no graph is a sign that the RRD was unable to generate. This is normally because of a configuration issue, and I seem to get them when my hobbitgraph.cfg section is wrong.

I get the impression that your DEF line is incorrect in your hobbitgraph.cfg file.

by using DEF:tr=trackoswex.rrd:tracks:AVERAGE, you are telling the grapher to use the trackoswex.rrd file and "tracks" as the name of your datasource. Is your datasource's name really "tracks"?

To find the name of your real datasource from a simple rrd file, do this:

rrdtool dump /path/to/your.rdd | less

Then search for the <ds> tag. (Should be right near the top.) For instance, one of mine says:

    <ds>
            <name> procATemp </name>
            <type> GAUGE </type>
            <minimal_heartbeat> 600 </minimal_heartbeat>
            <min> 0.0000000000e+00 </min>
            <max> NaN </max>

            <!-- PDP Status -->
            <last_ds> UNKN </last_ds>
            <value> 6.4550000000e+03 </value>
            <unknown_sec> 0 </unknown_sec>
    </ds>

So my datasource's name is procATemp. Note that this only works for a simple .rrd file. Some rrds contain several data sources, so don't let this mislead you.

HTH,

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 YAXIS Number of tracks DEF:tr=trackoswex.rrd:tracks:AVERAGE AREA:tr#00CCCC:Tracks COMMENT:These are the number of tracks received in the last 120 minutes.\n GPRINT:tr:LAST: \: %5.1lf (cur) GPRINT:tr:MAX: \: %5.1lf (max) GPRINT:tr:MIN: \: %5.1lf (min) GPRINT:tr:AVERAGE: \: %5.1lf (avg)\n

This defines which RRD files to include on the "trends" column webpage,

and the order in which they appear.

GRAPHS="la,disk,inode,qtree,memory,users,vmstat,iostat,tcp.http,tcp,netstat,mrtg::1,temperature,ntpstat,apache,bind,sendmail,mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,trackoswex"

NCV_trackoswex="trackoswex:GAUGE"

Any help would be appreciated!

tks
