Yes, you are using the NCV method, instead of the explicit
"pitcher/catcher" method. Which do you want to use?
If you use NCV, the Hobbit server will make a valiant attempt to pick
out your data from the text of your message, but only if it is in the
proper format. This is a can of worms I quickly threw overboard when I
started adding my own custom tests.
If you bind a column (text) to NCV, the custom parser script will not be
called.
Look in the NCV section of the hobbitd_rrd man page to see how the data
needs to look. You need to make sure that your are sending "cputemp :
<number>" or "cputemp = <number>" somewhere in your status message. Or
maybe it has to be "cputemp:<number>" or "cputemp: <number>" -- see why
I never got it to work? The documentation is hazy about whether or not
spaces are required, and which combinations will be okay or not. This
is why I quit trying and went for the use-my-own-sledgehammer approach.

I am completely clueless. OK, sanity check requested. According to
existing docs on the site, i made the following changes, but all i get
on the graph page is
hobbit graph ncv:cputemp
Now, if my data was bad, i'd have a blank graph, one where all the
values show as "nan." I'm not even getting that, so i am back even
further than i thought. I have...
in hobbitlaunch.cfg
[cputemp]
ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
CMD $BBHOME/ext/cputemp.sh
LOGFILE $BBSERVERLOGS/cputemp.log
INTERVAL 1m

TIA. I have a feeling the key is something in here. somewhere. somehow.

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."
OH, so, you know how to craft your greps and awks based on the MSG you
are sending from the client, is that it? I don't need to find and
examine that passed data, because i can see its structure based on the
$MSG i am sending at the end of the client script. Right?
(please don't laugh at my code):
shyeah, like i'm qualified to do so.
case $TESTNAME in
foo)
# Snag each foo data line
FOO_ALL=`grep "FOO_Events:" $FNAME | awk '{print
$3}'`
this is where i was getting conf00zed. I was wondering what psychic
powers you people were employing to know how to pick out what you
wanted blindly :).
# Print out RRD Foo Dataset definitions
echo "DS:Events:GAUGE:600:0:U"
echo "DS:Notifications:GAUGE:600:0:U"
echo "foo.rrd"
echo "$FOO_ALL:$FOO_NOTIFY"
and this i'll just have to look up to make sure of.
Thank you! I think it's starting to coalesce in my congealed brain...

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,
