RE: [hobbit] RRD error in updating the rrd files

["Gada, Subhash" <subhash.gada (at) logicacmg.com>]

Hi,

Thank you all very much for the support.

Special thanks to Taylor Robert, Hubbard Greg L & 


I managed to make the graphing work for custom tests.

I debugged the script by redirecting the values to a log then I
understood that the variable 'v' is having null value for which it is
reading from the $line.

Here is the script.

Once again my hurtful thanks to hobbit mailing list.


 #!/bin/sh

# Input parameters: Hostname, testname (column), and messagefile
HOSTNAME="$1"
TESTNAME="$2"
FNAME="$3"


if [ "$TESTNAME" = "printq" ]
then
i=0
cat $FNAME |   \
while read line
do

if [ $line ]
then
v=`echo $line | grep "^PRN*" | awk -F: '{print $2}'`

#DS names
dsn=`echo $line |grep "^PRN...:" | awk -F: '{print $1}'`

# The RRD dataset definitions
echo "DS:qlen:GAUGE:600:0:U"

# The filename
echo "printq,$dsn.rrd"

echo $v

let i=$i+1
fi
done
fi

exit 0

I don't know what is wrong, but I debugged my custom scripts using these
methods:

A) I changed my script to save the temporary file.

B) I run the "catcher" by hand using the temporary file as input, and
review the output.

There are many variations you can use.  For instance, you can simply
grab and save the text in the Web page for your new test, and this will
be essentially the same as what is in the temporary file that you are
given.

You can also add a log file mechanism for the script, and add whatever
you want to it.  Make sure you don't put in too much and forget about,
since Hobbit will tirelessly run your script every 5 minutes until the
12th of Never or your computer croaks, whichever comes first.

Subject: [hobbit] RRD error in updating the rrd files

 
Hi,

I have written a script to create rrd files for custom test called as
'printq'

The data which comes to hobbit  for the 'printq' test is random.

So I have decided to generate separate rrd file for each value.

I could see the following error in the rrd status log.

2006-03-20 16:40:07 RRD error updating
/home/hobbit/data/rrd/xx.xxxxxx.com/printq,PRN095.rrd from
xxx.xxx.xxx.xxx: expected 1 data source readings (got 2) from
1142853006:0:U:...
2006-03-20 16:40:07 RRD error updating
/home/hobbit/data/rrd/xx.xxxxxx.com/printq,PRN096.rrd from
xxx.xxx.xxx.xxx: expected 1 data source readings (got 2) from
1142853006:0:U:...

Can any one please let me know what is going wrong in updating the rrd
files.


The script is as follows.

#!/bin/sh

# Input parameters: Hostname, testname (column), and messagefile
HOSTNAME="$1"
TESTNAME="$2"
FNAME="$3"


if [ "$TESTNAME" = "printq" ]
then

cat $FNAME |   \
while read line
do
#Value
v=`echo $line | grep "^PRN...:" | awk -F: '{print $2}'`

#DS names
dsn=`echo $line |grep "^PRN...:" | awk -F: '{print $1}'`

# The RRD dataset definitions
echo "DS:printq:GAUGE:600:0:U"

# The filename
echo "printq,$dsn.rrd"

echo $v

        done
fi

exit 0
