Asterisk SNMP Monitoring
Asterisk includes the res_snmp.so module designed to provide monitoring information via SNMP. Very useful when used together with Zabbix remote monitoring.
Note: AstLinux 1.1.2 or later is required

Example: /mnt/kd/snmp/snmpd.conf
com2sec notConfigUser default public group notConfigGroup v1 notConfigUser group notConfigGroup v2c notConfigUser view all included .1 view system included .iso.org.dod.internet.mgmt.mib-2.system access notConfigGroup "" any noauth exact all none none syslocation Omaha, NE syscontact AstLinux - www.astlinux.org agentaddress udp:127.0.0.1:161 master agentx agentXSocket /var/agentx/master agentXPerms 0660 0550 sysObjectID .1.3.6.1.4.1.22736.1 mibs +ASTERISK-MIB
Restart snmpd service using CLI:
service snmpd stop service snmpd init
Example snmp commands using CLI:
# Linux uname -a snmpget -OQv -v2c -c public 127.0.0.1 SNMPv2-MIB::sysDescr.0 # System uptime snmpget -OQv -v2c -c public 127.0.0.1 SNMPv2-MIB::sysUpTime.0 # List network interfaces snmpwalk -OQv -v2c -c public 127.0.0.1 IF-MIB::ifDescr
