[asterisk-users] ASTERISK and SNMP

I use CentOS, and it works fairly well. But I had to piece together info from several places. I've tried it several different wants and this way worked, as long as asterisk is run as root.
Copy asterisk-mib.txt and digium-mib.txt from <asterisk_source>/doc to /usr/share/snmp/mibs/
mkdir /var/agentx
touch /var/agentx/master
My /etc/asterisk/res_snmp.conf
;
; Configuration file for res_snmp
;
[general]
; We run as a subagent per default -- to run as a full agent
; we must run as root (to be able to bind to port 161)
;subagent = yes
; SNMP must be explicitly enabled to be active
enabled = yes
My snmp.conf
rwcommunity private 127.0.0.1
rocommunity public
disk /
master agentx
agentXperms 0660 0550 root root
restart snmp and the /var/agentx/master should look like srw-rw---- 1 root root 0 Nov 25 11:31 /var/agentx/master
restart asterisk manually and you see a net-snmp connect.
export MIBS=+ASTERISK-MIB
You should be able to to do a snmpwalk -v 2c -c public localhost asterisk

please wait I found some issues in my con file
2009/11/27 mickael ropars <mropars at gmail.com>
I am running on Trixbox so my OS is Cent0S 5.4 and the Asterisk version is 1.4.22-4
on asterisk side Snmp module is running:
> module load res_snmp.so
== Parsing '/etc/asterisk/res_snmp.conf': Found
Loading [Sub]Agent Module
Loaded res_snmp.so => (SNMP [Sub]Agent for Asterisk)
see below my snmpd.conf file (I remove commented line for an easy reading)

What operating system do You have ? What asterisk version You compile ?
After install net-snmp do You recompile asterisk with res_snmp module ?
I'm used instruction from here
http://voxilla.com/2009/02/03/configuring-asterisk-snmp-support-1131
and everything work correctly.
BR,
Michał
