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.
