Hi Greg,

I Apologise for bothering you all with script debugging!

I thought of the following script, however I could not debug the script. I have the following questions?

I thought of taking advantage of the common letters PRN and grep it with "PRN*". Is this the correct way to grep the value?

Example data from server1 PRN327:0 PRN203:1 PRN202:0

Example data from server2 PRN123:3 #-----------------------name:value PRN314:0 PRN137:0 PRN136:0

The idea is to create separate rrd files of each value. The host which send the data to hobbit does not have a fixed number of name:values but maximum of 30

If I trigger the script with hobbd_rrd nothing is happening and the CPU utilisation is growing up to 90%

Around 25 hosts have the test "printq" running.

#!/bin/sh

Input parameters: Hostname, testname (column), and messagefile

HOSTNAME="$1" TESTNAME="$2" FNAME="$3"

index=0 if [ "$TESTNAME" = "printq" ] then

For test purpose looping fixed number of times.

while [ $index -lt 30 ] do p[index]=grep "^PRN*:" $FNAME | awk '{print $2}'

The RRD dataset definitions

echo "DS:$index:GAUGE:600:0:U"

The filename

echo "printq.$index.rrd"

#The data echo ${p[index]} let index=$index+1

#exit the loop when the value of $p{[index]} is null if [ $p{[index]} -eq "" ] then
exit fi done fi exit 0

Well, it does not appear to be that difficult. For each data element, you need to put out the DS line, then the file name, then the values. Make the file name match the element.

So, if F070 = 1, F001 = 2, F037 = 5

"DS:value:GAUGE:600:0:U" "F070.rrd" "1" "DS:value:GAUGE:600:0:U" "F001.rrd" "2" "DS:value:GAUGE:600:0:U" "F037.rrd" "5"

The Hobbit RRD support will do the right thing, creating these datasets in the directory for the associated host.

Then, in the Hobbit graph definition, you have to figure out how to use the wildcard mechanism to find all the F*.rrd files. The file names can be used to replace the parameter value "value" in the dataset would become F070, F001, F037, etc. This seems to be how the disk magic works.

Good luck!

Hi You can see the disk rrd handler in <source_code_home_dir>hobbitd/rrd/do_disk.c , who`s an include to hobbitd/rrd/do_rrd.c

Hi,

Yes the graph mechanism of disk suites similarly to the requirement.

Can any one explain how the the separate rrd files are created for different disk volumes. I couldn't trace how this is happening.
