I've read the archived messages, the man pages and the doc and I still can not seem to get this right.
I have an external test that sends a message to Hobbit, something like this:
status vm1.sp_util green 21 Oct 2005 06:28:31 Spool Utilization 16 %
(this is what is sent by the external script, is there a way to see what is actually received?)
I've modified the 'extra.sh' script to check for this test:
if [ "$TESTNAME" = "sp_util" ]
then
# Analyze Spool Utilization message
SP_UTIL=`grep "Spool Utilization" $FNAME | awk '{print $10}'`
# The RRD dataset definitions
echo "DS:sp_util:GAUGE:600:0:100"
# The filename
echo "sp_util.rrd"
# The data
echo "$SP_UTIL"
fi
I've added 'sp_util' to the --extra-tests option in the rrdstatus section of hobbitlaunch.cfg
I've added this section to hobbitgraph.cfg:
[sp_util]
TITLE Spool Utilization
YAXIS Spool Utilization
DEF:avg=sp_util.rrd:sp_util:AVERAGE
CDEF:sp_util=avg,100,/
AREA:SP_UTIL#00CC00:Spool Utilization
-u 1.0
GPRINT:sp_util:LAST: \: %3.0lf (cur)
GPRINT:sp_util:MAX: \: %3.0lf (max)
GPRINT:sp_util:MIN: \: %3.0lf (min)
GPRINT:sp_util:AVERAGE: \: %3.0lf (avg)\n
An rrd file is being created and a link is being put on the status web page, but no graph is being displayed. Just the text 'hobbit graph sp_util', which is the alt tag in the img definition.
This leads me to believe that there is something wrong with the graph image itself.
Are all of these steps correct, where did I go wrong?
Thanks.
