How to Connect Prometheus with Vodia PBX

Published on:

July 24, 2024

Integrating Prometheus with Vodia PBX enables effective monitoring of your phone system’s performance. Start by creating an API account on Vodia PBX to grant access to Prometheus, followed by the installation of Prometheus on DigitalOcean. Update the prometheus.yml file to include your PBX as a target by configuring the DNS, username, and password. Explore the Vodia API for available system stats, such as CPU usage and memory. Finally, create custom stat panels in Prometheus to visualize and track these key performance metrics in real time.

Prometheus is an open-source monitoring and alerting toolkit that is part of the Cloud Native Computing Foundation. By integrating it with Vodia PBX, you can effectively monitor and manage your phone system's performance. Here’s how to get started:

Step 1: Create an API Account on Vodia PBX

To allow Prometheus to access Vodia PBX data, you need to create an API account. Follow these steps:

  1. Log in to Vodia PBX as an Administrator:
    • Navigate to the system level where you can manage user accounts.
  2. Create a New User Account for API Access:
    • Go to the Administrator section.
    • Create a new account with the following details:
      • Account: Choose a user name.
      • API Access: Enable API access.
      • Type: Set the account type to Regular.
      • Password: Set a strong, secret password.
  3. Save the Configuration:
    • Save the user account configuration.
    • Keep the username and password handy, as you will need them for Prometheus to access Vodia PBX data.

Installing Prometheus on Digital Ocean: https://marketplace.digitalocean.com/apps/prometheus

Once your server is set up, you can access the Prometheus user interface by going to http://your_server_ip:9090/

Setting up the .yml file

By default, Prometheus is set up to monitor itself and Node Exporter. To monitor more systems, you need to update the configuration file located at: /etc/prometheus/prometheus.yml

Download Prometheus.yml

3 things need to be changed in the Prometheus .yml file config file

  • targets: ['123.vodia.com'] Here is where you will set the target - in this case it will be your PBX DNS name
  • username: 'prometheus'
  • password: 'prometheus'

Note: Do not remove the ' ' and [ ] in the config file leave it as is and change the value

Once you have edited the config file, you can modify the prometheus.yml using nano or any edit you desire by copy-pasting the config or simply creating a new .yml file and renaming the old file.

Restart the service by sudo systemctl restart prometheus

Creating a stat panel on Prometheus

Click "add panel" and enter the Vodia API cmd - in this case system_cpu_srv_max, then press execute: you can create many panels to monitor the PBX.
