Problem with hobbitd_rrd custom graph

Hi all,

I'm trying to create a custom graph for hobbit but am having some problems.

I have a script doing SNMP probing and returning status messages to hobbit. I have another script that generates RRD definitions for hobbitd_rrd.

I've added the script to hobbit_rrd extra_scripts:
[rrdstatus]
         ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
         NEEDS hobbitd
         CMD hobbitd_channel --channel=status --log=$BBSERVERLOGS/rrd-status.log hobbitd_rrd --rrddir=$BBVAR/rr
d --extra-script=/usr/lib/hobbit/server/ext/sensatronics-grapher.py --extra-tests=temp --debug


I've also made a graph definition in hobbitgraph.cgi (not really the finished definition, but I think it should work for testing):
[temp]
         TITLE Sensatronics environment monitor
         YAXIS Measurement

         GPRINT:11:MIN: \: %5.1lf (min)
         GPRINT:11:AVERAGE: \: %5.1lf (avg)\n


Now, the rrd file is created but only occasionally do I see values entered into it (I haven't seen a pattern - looking over the rrd generated over the weekend I see some values, sometimes 30 minutes apart, sometimes hours, but almost all the measurement points show NaN)

My script is being executed every 5 minutes.

Here is the output from rrd-status.log (with hobbitd_rrd run with --debug flag):

That sounds exactly the same problem I was having. What version is your hobbit installation? If recent source (ours is 4.3.0, and I don't know when the caching went in), it could be that this is your answer. http://www.hswn.dk/hobbiton/2008/09/msg00283.html

Check back through that log and see if you have occasional lines like
Flushing '/<hostname>/temp.rrd' with 1 updates pending, template '11:12:13:21:31:41:42'
just before the "Unlinking temp file" entries, corresponding to when you saw points on the graph.

Are you trying to graph 7 different data points with that one string of numbers.

Are you triggering this with the ncv module in hobbitserver.cfg?

Hi Graham,

Good find, thanks! I haven't tried the fix yet, but given your description of it and that our snapshot does include the RRD cache mechanism I think it's safe to say this is it. I'll try your patch tomorrow.

Kind regards,

Davíð

Check the rrd file with "rrdtool info /path/to/rrdfile.rrd" and verify
that the "ds" lines show up as GAUGE. It sounds like you might have
created the rrd file using COUNTER (the default).

Hi all,

I'm trying to create a custom graph for hobbit but am having some problems.

I have a script doing SNMP probing and returning status messages to hobbit. I have another script that generates RRD definitions for hobbitd_rrd.

I've added the script to hobbit_rrd extra_scripts:
[rrdstatus]
        ENVFILE /usr/lib/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD hobbitd_channel --channel=status --log=$BBSERVERLOGS/rrd-status.log hobbitd_rrd --rrddir=$BBVAR/rr
d --extra-script=/usr/lib/hobbit/server/ext/sensatronics-grapher.py --extra-tests=temp --debug

I've also made a graph definition in hobbitgraph.cgi (not really the finished definition, but I think it should work for testing):
[temp]
        TITLE Sensatronics environment monitor
        YAXIS Measurement
        DEF:11=sensatronics.rrd:11:AVERAGE
        DEF:12=sensatronics.rrd:11:AVERAGE
        DEF:13=sensatronics.rrd:11:AVERAGE
        DEF:21=sensatronics.rrd:11:AVERAGE
        DEF:31=sensatronics.rrd:11:AVERAGE
        DEF:41=sensatronics.rrd:11:AVERAGE
        DEF:42=sensatronics.rrd:11:AVERAGE
        LINE2:11#00CCCC:value
        COMMENT:\n
        GPRINT:11:LAST: \: %5.1lf (cur)
        GPRINT:11:MAX: \: %5.1lf (max)
        GPRINT:11:MIN: \: %5.1lf (min)
        GPRINT:11:AVERAGE: \: %5.1lf (avg)\n

Now, the rrd file is created but only occasionally do I see values entered into it (I haven't seen a pattern - looking over the rrd generated over the weekend I see some values, sometimes 30 minutes apart, sometimes hours, but almost all the measurement points show NaN)

My script is being executed every 5 minutes.

Here is the output from rrd-status.log (with hobbitd_rrd run with --debug flag):

Any ideas?

Hi Henrik,

Thanks for this, my values were defined as GAUGE but the problem was fixed by the patch submitted by Graham Nayler. This hobbit install is running a 4.3 snapshot from late 2007.

See this mail for the referenced fix: http://www.hswn.dk/hobbiton/2008/09/msg00283.html

After applying, I can confirm that values are coming into the database at every run so far.

Now to finish the graph definition. :)

Kind regards,
Davíð
