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.  Thanks!

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.  Thanks 

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

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!!
