Custom script, rrd file, GAUGE datatype , UNKN

[Anna Jonna Armannsdottir]

I have created a GPL Hobbit module to monitor
Flex License Manager. It seems to be working 
and delivering data in Hobbit under the column 
flexlm . 

On the server, the hobbitserver.cfg file has been 
changed like so: 
TEST2RRD="cpu=...  ... flexlm=ncv"
Data is delivered in the RRD file flexlm.rrd 

The data arrives OK into the rrd file, with the 
correct number of used licenses in last_ds 
field with the default data type DERIVE. 

SO far so good, but for the graphs, the datatype 
should be GAUGE. 

So I added the following line to hobbitserver.cfg : 
NCV_flexlm="MATLAB:GAUGE" 

I have tested this a few times, being extra careful to do: 
~/server/bin/bb 127.0.0.1 "drop jotunn.rhi.hi.is flexlm" as hobbit user
then after stopping the server:

rm /var/lib/hobbit/rrd/jotunn.rhi.hi.is/flexlm.rrd

Start the server a minute later. 

Then the last_ds field is set to UNKN like in the following example. 

<!-- Round Robin Database Dump --><rrd> <version> 0003 </version>
        <step> 300 </step> <!-- Seconds -->
        <lastupdate> 1211985894 </lastupdate> <!-- 2008-05-28 14:44:54
GMT -->

        <ds>
                <name> MATLAB </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> 5.8800000000e+02 </value>
                <unknown_sec> 0 </unknown_sec>
        </ds>

I wonder if this has something to do with the fact that the 
output format from my flexlm module to Hobbit is: 
$AWK '{printf "%.19s : %d\n", $3, $11 }' 
Resulting in lines like this: 
MATLAB : 1 

Maybe it is the \n in the format string or maybe 
there should be a space after the number. 

I am stuck here. Can anybody help me out. :) 
BTW: I am using Hobbit 4.2.0 with the allinone patch.
