Nagios plugin script for use with JMXProxy
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
All,
I have developed a Perl script that can be used with Nagios to check
on a Tomcat instance via the manager's JMXProxyServlet. Someone asked
me to publish it, which I'm happy to do. I'm just wondering what the
best thing to do is.
I see several options:
1. Submit a patch to the Tomcat source
2. Drop the file into the Tomcat wiki
3. Stick the file on Apache's related-projects stash
-- I have forgotten the address at this point :(
4. Host it on my own website
Tomcat's source doesn't include a "contrib" directory or anything like
that, so probably #1 isn't the best option, but I figured I'd mention
it in case someone wants to tell me a better place in the Tomcat
source I could put it.
I'm not sure the wiki is the best place for things like scripts. At
least it will be available and versioned-with-history: anyone can make
modifications to it and everyone benefits.
Does anyone have any suggestions as to which way I should go?
Thanks,
- -chris

First glance at the code - looks nice, and it looks like it will play
with Icenga. If I have time in the next few days I'll try to add and
configure it.
Unfortunately, I have to move on December 1st, and I've yet to find a
place to move to. That takes first priority (although I could always
participate from various open wifi spots :-| )
And your Wiki start is nice - much nicer than the blank page I've got
going for clustering. Maybe in a few weeks.
. . . . life takes priority so only a penny's worth this time.

Heh. My website gets a trickle of hits per day, and those are probably
just spiders.
I'll link to it from the aforementioned wiki page. We can always move
it somewhere else.
Let me know if it will work for you in Icinga.

Chris,
First of all, thank you for this. I've been toying with a similar idea
(and plugging the entire mess into the Icenga remoting script), but I've
not had the chance.
Right now, I think the Wiki might be a good place. Maybe under the
"Troubleshooting" section? I don't know, there doesn't seem to be a good
monitoring section in the How To area of the Wiki.
Maybe you could start one?
The fact that you have forgotten the related projects' stash URL is a
good indication that most people don't know of it, or have forgotten it,
or are otherwise unaware of it. I know I am. So unless the location gets
broadcast pretty strongly, then your good work will go off to the dusty
bin of unvisited URLs.
Your blog is great as well, I just don't know how much extra access and
traffic you're looking for . . .
. . . . just my two cents

AFAICT, they do not provide hosting... only listings. So, I still need
a place to actually put the code.

Many thanks from me as well.
Indeed Nagios has a third-party plugins corral, you can reach it at
http://exchange.nagios.org/directory/Plugins
There you can also find instruction there on how to submit your own project
