[hobbit] Passing non-linux data to hobbit for monitoring and graphing.

Tue Oct 17 19:26:13 CEST 2006

It looks to me like you have at least three choices:

A) modify your mainframe agent so it sends data that closely mimics a
currently supported system.  The easiest way to do this is to pick a
"supported system" and then get the agent output from it and roll up
your sleeves.

B) Let your mainframe agent send what it sends, but then modify the
Hobbit source code so that the mainframe OS is added to the support
list.  Perhaps you can convince the ever-busy Henrik to do this for you
if you can supply him with likely output, like what you just sent.

C) Bite the bullet and add some new columns that are unique to your
mainframe system, and write an extermal script to review and parse the
output and add to appropriate RRD's.  Then create the necessary graph
definitions, and update Hobbit to use them.  There is useful
documentation for how to do this in the standard Hobbit pages.

To me, "B" is the best long term approach, because I bet you may not be
the only person who ever runs Linux on the mainframe and wants to manage
it with Hobbit (though open source mainframe management does sound
oxymoronish).  "C" gives you the chance inject meaningful new content
(channel info) that won't be found on any x86 Linux system you want to
emulate.  But "A" would help your mainframe system conform to the other
systems.

Other options are left to the reader as an exercise... :)

Hello.

I have a non-linux system that I want to supply data to a hobbit server
for monitoring. This is a z/VM system on an IBM mainframe. I have a
client from Rich Smrcina. Using this client as a template, I want to
pass other data to hobbit for monitoring and graphing. I have seen the
hobbit webpages and graphs showing data like CPU utilization (System,
User, IDLE) and User/Proc counts.  Is there a manual that details what
fields in what hobbit status messages are recorded and graphed by the
default hobbit installation? I would like to know more about what each
of the default tests is supposed to show so that I can transform my
system's data into the format hobbit is expecting. I would rather not
report data to new test columns until I cannot wedge my data into a
hobbit format, like a status for my system backups.
