Hello
I'm trying to create an extra script for hobbit_rrd. I've followed
tutorials found on the net, especially
http://www.trantor.org/theshire/doku.php/tutorials:customgraph
I'm getting the information in the status page. Data is correctly sent
to the hobbit server.
Everything seems to be configured correctly, but I'm not getting any rrd
data. In the configurations, I've double-checked paths, execution
rights, etc.
To simplify the tests, I've changed my extra-script so that it writes
everything in a temporary file.
The script isn't started : it doesn't write in this temporary file.
In the rrd-status log, I don't see anything about executing the extra
script.
hobbitlaunch.cfg :
----------------------------------------------------------
[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/rrd
--extra-script /usr/lib/hobbit/server/ext/rrd_openvz.sh --extra-tests
openvz --debug
----------------------------------------------------------
/usr/lib/hobbit/server/ext/rrd_openvz.sh :

messagefile=$3
echo "Host $hostname" >> /tmp/plouf
echo "Test $testname" >> /tmp/plouf
echo "Message file $messagefile" >> /tmp/plouf
cat $messagefile >> /tmp/plouf
exit 0

Could anyone see something that would be wrong there ?
Thanks in advance :)
