Hey Rob,

What is being passed is all the text you so carefully sent in your client-side text. That is why it is important to "pitch" what you can "catch."

When your custom, server-side, RRD-parsing script is called by the Hobbit server, it will be called with three parameters. One of these parameters is the fully qualified name of a file that you can open and read. When your script exits, the Hobbit server will delete the file.

Look in the man pages for hobbitd_rrd, and look at the section called "Custom RRD Data via Scripts"

GLH

Here is an example of this script, based on what I actually use (please don't laugh at my code):

#!/bin/sh

Custom script to parse non-standard files to get data for RRD datasets

Designed to work with the open source "Hobbit Monitor" system

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

MYNAME="example-rrdparser"

DEBUG=1 # Set to 1 or uncomment to enable debugging output in log

LOG="/opt/hobbit/server/log/$MYNAME.log" NOW=date '+%d-%h-%Y %H:%M:%S'

Each test name corresponds to the column name used by whoever posts

the

data. At the very root level, this is specified when bb is called to

send the message.

case $TESTNAME in

    foo)
            # Snag each foo data line

            FOO_ALL=`grep "FOO_Events:" $FNAME | awk '{print $3}'`

            if [ "$FOO_ALL" = "" ]
            then
                    FOO_ALL="U"
            fi

            FOO_NOTIFY=`grep "FOO_Notifications:" $FNAME | awk

            if [ "$FOO_NOTIFY" = "" ]

I'm askin' the wrong questions, i just realized.

For custom test Foo which has Custom Script Foo.sh, which is a clientside script living in ~/client/ext;

assuming all other .cfg acrobatics have been accomplished, where on the server am i going to find the raw $host.foo data/numbers for me to parse and pass on?

I understand i can maybe copy someone else's macro for it, but i need to see what the raw data looks like so i know what i'm parsing :D.

tia,
