snmp configuration on Linux (snmpd.conf) NET-SNMP

Hi All,

I am going to show you how to configure the snmp agent on a Linux based distribution — this example is tested on CentOS and Red Hat Linux

Purpose:

The purpose of installing SNMP (Simple Network Management Protocol) is to monitor host resources like CPU, Memory, Network and Disk Utilization etc.

SNMP is a network management protocol used to send and receive
messages between NMS (Network Management Systems). SNMP allows NMS to manage network devices remotely, by using MIBs .

You might be wondering what are MIB ?
MIB’s are Management Information Base, It can be best described as information in the form of variable that would be useful to manage the specific item. The developer who creates a MIB has to create a OID aka Object Identifiers

Now you might be wondering whats OID ?
An object identifier is simply a unique id represented by a series of numbers and point that has a unique corresponding name. The format of OID is a sequence of numbers with periods /dots in between.

example of Print Device OID is like this:
1.3.6.1.2.1.43.10.2.1.4.1.1
This is HP Printer Total Page Count.

To learn more about MIB’s and OID’s please Google it, as I am still learning about it too its a huge topic on its own.
