SNMP monitoring
Hi everybody,
How would I set up SNMP monitoring of my Solr server? I've done some
searching of the wiki and Google and have come up with a blank. Any
pointers?

it depends on what you want to monitor. if you just want to know what the
JVM is running, this should be fairly easy...
if you wnat to be able to get Solr specific stats/data your best bet is
probably to look into ways to access JMX MBeans via SNMP (there seem to be
some tools out there to do things like this)

which is totally fine ... not every doc on the wiki needs to be container
agnostic, my point was just that i didn't want to misslead the "casual
reader" who might see SNMP linked to off hte main page and assume it
will work for them. JBoss users will see it, and people really interested
in SNMP will search for it and fine it -- and if those people want to test
it / expand the docs to provide instructions for additional containers, we
can worry about updating the docs at that time (migrating JBOss specific
stuff to hte JBOss page, linking to the SNMP page fro mthe main page,
etc...)

Hi Chris,
Good points.
I originally thought of putting it in the JBoss section, however I
thought it was important to stress that SNMP monitoring (which is part of
"operations and production") can be done, with a footnote that it is done
through SNMP. This is where tree-based documents fail us; SNMP/JBoss should
be under ops&prod due to SNMP, but installation&configuration because of
JBoss.
Should we add a sub-bullet to the main page for SNMP under JBoss? Or
should we rename the document SolrJBossSNMP and put it under ops&prod? I
want people to be able to come to the main page and find SNMP there.
You're right, the doc is written only paying attention to the JBoss
SNMP-sar. Maybe I could change this... but unfortunately I never tried it
with any other container (in fact, I don't know of any other service that
does the same thing that JBoss does).
Sincerely,
Daryl.

Two things:
*1) Solr-Wiki or "contrib"?*
You know what... I've been thinking this over, and although people have
already expressed interesting in a Solr-wiki page for JBoss-SNMP, I'm
wondering if this would be better to be included as a "contrib" segment of
code. There are pros/cons to each approach. Some things to consider are:
- If it's in contrib, users have to know to look for it (a wiki page
telling them about it could solve this).
- If it's in contrib, we have a place for the code to live, so we
could make sure it continues to compile as Solr evolves.
- Fully-working SNMP usually requires you have your own *organization
ID* of some kind, so we could at best have a half-implementation, that would
not be testable.
- Because it requires JBoss in order to run, it won't be testable.
Alternatively, I could stick to the wiki-page approach, and just
include large bits of sample code in the wiki page, or include smaller code
snippets in the wiki page *and* include a zip of some more substantial code.
What do you think?
*2) Exposing Solr's CoreContainer*
Also, on a related note: My method of implementation was to expose the
solr CoreContainer by sub-classing SolrDispatchFilter and passing the
container into an MBean (essentially). I only did this because I had to, and
I would think a cleaner way to do it would be for Solr to provide a clean
way of accessing the protected "cores" object in the SolrDispatchFilter.
Is it possible to get the CoreContainer without resorting to such
tricks? (According to my research, it isn't, but I haven't read all of
Solr's code yet.)
And if not, is it possible to have Solr changed so that it can expose
the CoreContainer?
Let me know,
Daryl.

Hi devs,
A while ago I posted a question to the solr-users list asking about
SNMP monitoring of Solr. I got one reply suggesting the use of JMX-SNMP
bridges, but upon researching these I could find a) nothing that seemed
particularly good, and/or b) none of those that were free/OSS.
Since then I've found that deploying Solr in JBoss/Jetty with the
JBoss-SNMP SAR was the easiest way to get this job done. --But it still
wasn't "easy".
Thus, my question is; would anybody like to me write up a Solr-Wiki
page on how to expose Solr stats through SNMP? It's a bit involved, and is
JBoss-specific, however it is a useful feature that other Solr users may
benefit from. Let me know.
