Description:We had a need for doing better monitoring of Asterisk, and wanted to use SNMP to do this.  That way we can easily make pretty graphs with MRTG or what have you.

****** ADDITIONAL INFORMATION ******

Some time ago someone had implemented an SNMP agent for Asterisk, but it seems it did not get maintained.  I wrote a new implementation from the bottom up, including a (temporary?) MIB to go with it.  I did take the liberty of using Digium's enterprise number for this MIB.

For what is implemented so far, there are basically *no* changes made to the Asterisk core.  Some more additions can (and will) be made to this without having to make any changes to the rest of Asterisk.

Long term some changes should (will?) be made to Asterisk, to expose more data to the agent.

The agent is capable of running either as a full agent on port 161 (Asterisk must run as root in order to do this), or as a Subagent using the AgentX protocol.  It requires Net-SNMP to build (and to run, if running as a Subagent).

Made some changes to not return values held directly in channel structs, for stability.  Also some style changes requested by markster.

Hi tholo, i have recently compiled against asterisk 1.2.4 but give me this error.

[res_snmp.so]Feb  8 11:47:19 WARNING[783]: loader.c:325 __load_resource: /usr/lib/asterisk/modules/res_snmp.so: undefined symbol: agent_thread
Feb  8 11:47:19 WARNING[783]: loader.c:554 load_modules: Loading module res_snmp.so failed!

i have in the /etc/asterisk/res_snmp.conf
[general]
subagent=yes

Any tought???

Fixed Makefile problem where the bulk of the agent code was not linked into res_snmp.so -- thanks enmaca!
By: Enrique Martinez (enmaca) 2006-02-08 12:08:41.000-0600

The asterisk mib file has some formated issues there are a fixed mib file, by the way asterisk 1.2.4 with res_snmp.so loaded seems to deadlock a sip call i need to review the scenario

Regards

Some of the changes made to the MIB are wrong -- specifically things like changing "astChanEntry" to "AstChanEntry" in "astChanTable SEQUENCE OF astChanEntry" -- "AstChanEntry" is a syntax description, while "astChanEntry" is an actual entry.

The one valid change I can see is adding a reference to the index for astChanTypeTable, which is incorporated now in my version.
By: Enrique Martinez (enmaca) 2006-02-09 11:17:59.000-0600

Im a newbie in the mibs description but i cant load the mib in adventNET SNMP Utilities unless i make the changes "astChanEntry" -- "AstChanEntry"
By: Thorsten Lockert (tholo) 2006-02-09 11:25:31.000-0600

I looked at things again, and yes, you are right.  Fixing this now...  Will put up a new version in a few minutes with this and some other stability fixes, as well as a version that can be built outside of the Asterisk tree (both against 1.2.* and against HEAD)...
By: Thorsten Lockert (tholo) 2006-02-09 11:28:58.000-0600

The files "snmp.diff", "snmp-v2.diff", "snmp-v3.diff" and "asterisk-mib.txt" should be removed.
By: Olle Johansson (oej) 2006-02-09 12:30:34.000-0600

tholo, this is very cool. I will take a look at this. We will have to have some internal APIs so that other modules, like chan_sip, can provide data to the snmp agent.

Architecture-wise, I've been thinking along two different ways of doing this, either as a res_ module like you did, or as a separate piece of software, hooking up over the manager interface.
By: Thorsten Lockert (tholo) 2006-02-09 12:35:29.000-0600

The manager interface is, in effect, unusable.  Because if you do a query over that which has a fair bit of data (e.g. active channels on a busy instance), you only get the first bit of the return value.

This is also very much a work in progress, and much more information need to be available.  However, the initial goal was to:

- Provide the information *we* needed
- Be as un-intrusive to the rest of Asterisk as possible

As such, this requires no changes to Asterisk whatsoever.  That does, as you can imagine, somewhat limit what information is available.  But fixing that is to be the next step -- but *something* is much better than *nothing*, and this at least allow us to easily graph how busy our Asterisk instances are...
By: Olle Johansson (oej) 2006-02-09 12:39:47.000-0600

Just a small comment from looking at the source:

We are trying to use enum-like constructs instead of those long lists of #define's nowadays...

Maybe agent.c should be named snmpagent.c to be a bit more clear.
By: Olle Johansson (oej) 2006-02-09 12:40:45.000-0600

"There is no interface to get the list of currently supported
* technologies from Asterisk.  But there is a way of retrieving
"

Hmm. We can do that in "show channeltypes" so it should be possible if we just publish the channel list as a global variable.
By: Olle Johansson (oej) 2006-02-09 12:44:25.000-0600

Can't find the sample config mentioned in the makefile...
By: Thorsten Lockert (tholo) 2006-02-09 12:44:33.000-0600

Yes, and Mark has committed to adding an interface to walk the list of channel types much like we have for walking channels.

But look again at the *initial* goals of being non-intrusive... ;-)

As for using enums instead of defines...  I don't really see that it makes that much of a difference, and this was coded to be somewhat more like how any and all other SNMP agents are done.

As far as naming "agent.c" with an "snmp" prefix in the name, that is pretty much done already by putting it in res/snmp/agent.c in the source tree...  I mean, we don't have to be redundant either...?
By: Mark Spencer (markster) 2006-02-11 10:46:44.000-0600

I added the channeltypes list, it returns an ast_variable list which can be free with ast_variables_destroy...  Awaiting updated patch!
By: Thorsten Lockert (tholo) 2006-02-12 18:24:53.000-0600

Integrated diff updated and uploaded as "snmp.diff", which is now the current version.
By: John Todd (jtodd) 2006-02-12 23:05:08.000-0600

For giggles, this is the command to walk the "Asterisk" portion of the tree, assuming that "public" is the snmp community:

snmpwalk -v 1 127.0.0.1 public  .1.3.6.1.4.1.22736

or

snmpwalk -v 1 127.0.0.1 -c public  .1.3.6.1.4.1.22736

or

snmpwalk -m /usr/share/snmp/mibs/asterisk-mib.txt -v 1 127.0.0.1 -c public  .1.3.6.1.4.1.22736

Now, I ran this as an "agent" (not a sub-agent) and I'm somewhat confused on how to change the community string.  I figured it would be in the "normal" place that snmpd installed it - /etc/snmp/snmpd.conf in my case.  I changed my community name to something other than "public" to make a negative test... but "public" still walked the tree.  Is this picking up the community from the global config file or is there somewhere else that it's stored?

On RH9 (redhat 9), I had to jump through a lot of dependency hoops.  Obvious ones like "net-snmp-devel"  and "net-snmp" but less obvoius ones line elfutils-libelf-devel, bzip2-devel.  

Plus, Tholo sez: 'Comment out the "LDFLAGS+=$(shell net-snmp-config --ldflags)" line  [in res/Makefile]-- your net-snmp is too old to understand it.'

eagerly watching this developement, let me know where i can send the redbull.
By: John Todd (jtodd) 2006-02-13 09:41:23.000-0600

If I perform a the SNMPwalk command (as describe above) during an active call, Asterisk locks up and requires a "kill -9".  The values come back appropriately from the SNMPwalk, though...
By: damin (damin) 2006-02-13 10:25:45.000-0600

Hmmm... It seems to me that it would be totally awesome for debugging purposes if we could have the MALLOC_DEBUG routines actually dump data to SNMP. Imagine being able to plot the memory usage of various modules as well as core PBX functions over time? Many advanced developers can sort of do this in their head (I've seen Mark do it, in Chicago when we tracked down a memory leak in app_dial), but for mere mortals, visual representations are often far more effective. This might be a way to get more people engaged in the developer process.
By: Thorsten Lockert (tholo) 2006-02-13 10:27:30.000-0600

Missed a couple of error returns, which could (did!) cause deadlocks.  snmp-v5.diff corrects this.
By: Thorsten Lockert (tholo) 2006-02-24 11:55:13.000-0600

I have uploaded new versions that have slightly more documentation.  All files except "snmp-v6.diff" and "res_snmp-v2.tar.gz" can be removed.

Note that the standalone version in "res_snmp-v2.tar.gz" can build against the 1.2 branch, whereas the patch in "snmp-v6.diff" can only build against trunk.

The standalone version can build against either, but does not use the same interface to get at the channel types as the integrated version -- this is the main difference between the two.

It also no longer attempts to pick up LDFLAGS from net-snmp -- this was empty where supported, but not supported on all distributions of net-snmp...
