SNMP Configuration Asterisk 11


Dicko that Recipe came from these forums… perhaps again I might suggest that FORMAL documentation on the subject is created. I just spent the last 30 min looking up or decoding what your comment said about asterisks res_odbc and found several out-dated material. Nothing for Asterisk Version 11 or FreePBX Version 12. Shall I risk following old documents? Or Can I get a better recipe that is supported by FreePBX.


That recipe was “linked to” by a forum member. It bears no Freepbx imprimatur Generally FreePbx has a great wiki. Google also can help you learn stuff like snmp. If you get impatient there is always ‘paid support’ linked above.


Awesome please provide me with the link on FreePbx Wiki that explains SNMP… because I did attempt to GOOGLE it and nothing came up. I agree that the wiki is great, however on this subject the documentation is weak.


Sorry I won’t do your research or work for you.


Right so what your saying is that there is no such documentation… I know because I have searched… Thanks for your help Dicko…

SNMP and MIBS comes up every so often, if anyone would like give back and do a little documentation in the wiki we can create an article in the appropriate location and provide access to write/edit those wiki pages. Typically what happens those that are using snmp in their environment are more of a commercial focused group, so stuff doesn’t always make it back in to the community.


I would be glad to if I can get my system working with some guidance…


I am sorry it didn’t work out but I tried to guide you, good luck elsewhere


You didnt do anything Dicko other than be snoody in your remarks. Dont bother responding if you dont want to help.


is there someone else other than Dick that could help out here…


I have gone through the exact same instructions and cannot get any monitoring software to read SNMP other than a PING has anybody else had any luck?


Unfortunately it seems nobody wants to help. Unless I pony up and pay them.

I am definitely no SNMP guru but I am getting something by following that document…

I did have to play with the snmpwalk command given though…

By the way, I am running FreePBX 13/Asterisk 13…



# snmpwalk -v 3 -u USER -a SHA -A AUTHPASS  -l authPriv -x AES -X ENCRYPTIONPASS asterisk

ASTERISK-MIB::astVersionString.0 = STRING: 13.5.0
ASTERISK-MIB::astVersionTag.0 = Gauge32: 130500
ASTERISK-MIB::astConfigUpTime.0 = Timeticks: (154026) 0:25:40.26
ASTERISK-MIB::astConfigReloadTime.0 = Timeticks: (154026) 0:25:40.26
ASTERISK-MIB::astConfigPid.0 = INTEGER: 2416
ASTERISK-MIB::astConfigSocket.0 = STRING: /var/run/asterisk/asterisk.ctl
ASTERISK-MIB::astConfigCallsActive.0 = Gauge32: 0
ASTERISK-MIB::astConfigCallsProcessed.0 = Counter32: 0
ASTERISK-MIB::astNumModules.0 = INTEGER: 258
ASTERISK-MIB::astNumIndications.0 = INTEGER: 1
ASTERISK-MIB::astCurrentIndication.0 = STRING: us
ASTERISK-MIB::astIndIndex.1 = INTEGER: 1
ASTERISK-MIB::astIndCountry.1 = STRING: us
ASTERISK-MIB::astIndDescription.1 = STRING: United States / North America
ASTERISK-MIB::astNumChannels.0 = Gauge32: 0
ASTERISK-MIB::astNumChanTypes.0 = INTEGER: 14
ASTERISK-MIB::astChanTypeIndex.1 = INTEGER: 1
ASTERISK-MIB::astChanTypeIndex.2 = INTEGER: 2
ASTERISK-MIB::astChanTypeIndex.3 = INTEGER: 3
ASTERISK-MIB::astChanTypeIndex.4 = INTEGER


I can also retrieve a specific one by replacing asterisk with one of the entries I got (OID?).

This helps me, can’t guarantee it will work for anyone/everyone:

Install SNMP RPMs in Linux CLI:

yum install -y net-snmp asterisk-snmp net-snmp-utils

#Then you’ll need to update /etc/snmp/snmpd.conf to work for Asterisk. Google will have to help with this one.

edit /etc/asterisk/res_snmp.conf
subagent = yes
enabled = yes

#enable snmpd on start up and start snmpd
chkconfig snmpd on
service snmpd start

#And then load snmp res:
asterisk -rx ‘module load’


I am struggling to get this working on asterisk 13 glad to see someone else has gotten it going at least.

I followed a post associated with this and for the most part it all seems to have taken Compiling Asterisk with the res_snmp module

If i walk SNMP from .1.3.6 i get everything so i know my auth is working on v3, however I can’t get it to respond as asterisk specifically. Any ideas?

I have the asterisk rmp installed so that’s out of the way.

yum install asterisk13-snmp.x86_64
Loaded plugins: fastestmirror, kmod
Setting up Install Process
Loading mirror speeds from cached hostfile
Package asterisk13-snmp-13.9.1-1.shmz65.1.115.x86_64 already installed and latest version
Nothing to do

xagent appears to be firing up so we got that

May 17 13:37:13 3cx snmpd[45868]: Turning on AgentX master support.
May 17 13:37:14 3cx snmpd[45871]: NET-SNMP version 5.5

I believe the MIB is loaded as well since SNMP does respond to requests for it

snmpwalk -v 3 -u USER -a SHA -A PASS -l authPriv -x AES -X KEY astVersionString.0
ASTERISK-MIB::astVersionString.0 = No Such Object available on this agent at this OID

This doesn’t result in anything but an error for me unfortunatly. I think that may be the center of my issue… not sure?

asterisk -rx 'module load’
Unable to load module
Command ‘module load’ failed.

Go to the console and enter "find / -name ‘res_*.so’ "

This will tell you where your res_* reloadables are. If is not in the same directory as the rest of the resource drivers, you may have found your problem.

Sorry, the information I gave was based on the thread title for Asterisk 11.

With Asterisk 13 I have the same issue. I did some search but was not able to find a solution. If you go into the asterisk CLI and issue:

module load

you will find there is more info on why it’s failing, specifically about a problem with compile-time options. I think this is something that needs to be addressed by the distro people as the RPM (asterisk13-snmp.x86_64) appears to not be correct.

(Marbled) #31


The res_snmp module is not (no longer?) present on the distro… It looks like the support for SNMP has not been compiled in…

This can only be addressed by the FreePBX developers, I suggest you open a ticket on

Good luck and have a nice day!
