   Operating Systems:

Rocky 8

   Background:

This guide was written to setup a Zabbix server to monitor network devices and servers for interuptions of service. Zabbix will be configured to also send alerts through the local mail relay. It is assumed a local mail relay is already setup and configured.

Due to the length of the content, I opted to break the article into the following sections:

  1. Rocky Zabbix: Install
  2. Rocky Zabbix: Configure
  3. Rocky Zabbix: Setting up Discoveries
  4. Rocky Zabbix: Client Agent Setup
  5. Rocky Zabbix: SNMPv3: Setup and Configure
  6. Rocky Zabbix: SNMPv3: Adding Devices
  7. Rocky Zabbix: References
