SNMP Logging Flooding into /var/log/message

Another problem I have been facing with default installation of SNMP is the /var/log/message will be flooding with snmpd log as example above. To overcome this, add following line into /etc/sysconfig/snmpd using text editor:

OPTIONS="-LS 5 d"

Save and restart SNMPD to get affected. To verify, just run following command and make sure the options value is included:

$ ps aux | grep snmpd root 32382 0.0 0.1 197160 5076 ? S 13:04 0:00 /usr/sbin/snmpd -LS 5 d

This options will log from level 0 to 4 based on log level below:
0 – Emergencies – System is unusable
1 – Alerts – Immediate action needed
2 – Critical – Critical conditions
3 – Errors – Error conditions
4 – Warnings – Warning conditions
5 – Notifications – Informational messages
6 – Informational – Normal but significant conditions
7 – Debugging – Debugging messages
