Kamailio and SNMP HowTo
Here is a quick how-to on how to setup snmpstats module. This was on kamailio-1.4.4 and CentOS.
Make sure you install the prerequisites
yum install lm_sensors-devel net-snmp net-snmp-devel net-snmp-utils
Compile kamailio with snmpstats module
Add this to kamailio.cfg file
loadmodule "snmpstats.so" .. # ----- snmpstats params ---- modparam("snmpstats", "sipEntityType", "registrarServer") modparam("snmpstats", "snmpgetPath", "/usr/bin/")
Create a bare-bones /etc/snmp/snmpd.conf file
rocommunity public master agentx agentXSocket tcp:localhost:705
Create a /etc/snmp/snmpstats.conf file (this tells the snmpstats module where to send its snmp data).
agentXSocket tcp:localhost:705
If you are using a snmp.conf file, make sure this is in it
defVersion 2c defCommunity public mibdirs /usr/share/snmp/mibs mibs +ALL
Inside the /usr/share/snmp/mibs/ directory, append all OPENSER-* files with a .txt extension.
Testing
Start the snmpd daemon manually
snmpd -f -Dagentx -x tcp:localhost:705 2>&1
Restart kamailio and enjoy!
snmpwalk localhost openser
Should output something like this:
