One configuration SNMP

1. Installing NET-SNMP

sudo yum-y install Net-snmp

10.10.47.65 is the intranet IP of the host that installed the monitor and treasure plugin.

4. Restart SNMPD

sudo service snmpd restart

5. Verify that the SNMPD has been started

sudo netstat-tulnp|grep 161

Perform the following actions on any machine

The machine executing the snmpwalk needs to be documented in the snmpd.conf.

sudo snmpwalk-v2c-c public 10.10.47.65
