Working with SNMP monitoring

Now let's do something I enjoy most when working with Zabbix: build SNMP monitoring. My professional roots lie in network engineering, and I have worked a lot with SNMP monitoring to monitor all these different network devices.

Getting ready

To get started, we need the two Linux hosts we used in the previous recipes:

• Our Zabbix server host
• The host we used in the previous recipe to monitor via the Zabbix active agent

How to do it…

Monitoring via SNMP polling is easy and very powerful. We will start by configuring SNMPv3 on our monitored Linux host:

1. Let's start by issuing the following commands to install SNMP on our host.

For RHEL-based systems:

dnf install net-snmp net-snmp-utils

For Ubuntu systems:

apt install snmp snmpd libsnmp-dev
