Automated Network Monitoring: Adding Servers to LibreNMS with Ansible #

Adding servers to LibreNMS by hand is tedious, and should be done by automation. In this post, I’ll show you how I’ve automated the entire process of configuring SNMP and adding servers to LibreNMS using Ansible.

The Workflow #

Basically what the playbook does is:

Install and configure SNMP
Set up necessary firewall rules
Add the server to LibreNMS
Add it to the correct device group.

The Playbook #

Step 1: Installing SNMP Components #

- name: Ensure snmp is installed
  ansible.builtin.dnf:
    name:
      - net-snmp
      - net-snmp-utils
    state: present

The net-snmp package is needed for the SNMP daemon.
