Custom RRDs
list David Stuffle
I have created a custom RRD script and it been working fine. Any host that sends a "license" column status with a line containing "In Use: x" will get the license usage (x) graphed. But, for some reason it won't work on a host I have that has a hostname of "license". RRD file gets created, but it's all "nan" values. Could having the exact same hostname, Dataset name, and column name cause it not to work? The only other difference in this host is it's a Windows machine instead of Unix, but the status sent to Hobbit is the same so I can't see that it would matter.

It sounds to me like you are picking up the status line rather than the data line. Check your RRD script again... if you are grepping/awking for a line containing license you may need to narrow your criteria :-) It may be as simple as adding "tail -1" to make sure you only get the last occurence.

HTH, Andy.
I have verified I am getting the right data from the status by redirecting the script to a file. Somewhere between grepping the license count and putting it in the RRD file it gets lost. I'm figuring it must be because the hostname is the same as the DS name. Any other host I plug in to it works fine.

If you post the script and message content either here or directly to me, I'd be happy to take a look :-) Andy.

Thanks! Here is the script: (if the format gets messed up, I also attached
a file with the same contents)
#!/bin/sh
# Input parameters: Hostname, testname (column), and messagefile
HOSTNAME="$1"
TESTNAME="$2"
FNAME="$3"
if [ "$TESTNAME" = "license" ]
then
# Analyze the message we got
InUse=`grep "In Use" $FNAME | cut -d : -f 2 | sed "s/ //"`
# The RRD dataset definitions
echo "DS:license:GAUGE:600:0:U"
# The filename
echo "license.rrd"
# The data
echo "$InUse"
# Added for debugging purposes
if [ "$HOSTNAME" = "license" ]
then
echo $HOSTNAME, $TESTNAME, $FNAME >>license_test.txt
echo "$InUse" >>license_test.txt
cat $FNAME >>license_test.txt
fi
fi
The output from the debugging part (license_test.txt) looks like this:
license, license, /usr/local/hobbit/server/tmp/rrd_msg_27159
8
status license.license green Tue 05/10/2005- 7:37:41.18
Pro/Engineer Wildfire 2 Licenses
Total licenses available: 31
In Use: 8
And here's the RRD definition:
[license]
TITLE License Utilization
YAXIS Used Licenses
DEF:avg=license.rrd:license:AVERAGE
LINE2:avg#@COLOR@:Used Licenses
GPRINT:avg:LAST: \: %5.0lf (cur)
GPRINT:avg:MAX: \: %5.0lf (max)
GPRINT:avg:MIN: \: %5.0lf (min)
GPRINT:avg:AVERAGE: \: %5.0lf (avg)\n
Two other hosts are sending license statuses and they're graphing fine.
Just this "license" hostname is not. The graph shows up and the rrd file is
getting updated, but with no values.
Thanks again!!
