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:
Log in to Vodia PBX as an Administrator:
Navigate to the system level where you can manage user accounts.
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.
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.
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
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
Check the Prometheus and click on System Stats - this will show all of the available APIs for Prometheus, and you will see an Example Response. Click on "view more" and it should look like this:
I have bolded all of the stats you can use as an examples, there's no need to copy the whole thing
# pbxctrl 69.3.2.beta

# HELP system_cpu_srv_avg Average Load # TYPE system_cpu_srv_avg gauge system_cpu_srv_avg 0 1719852690061
# HELP system_cpu_ctrl_max Peak usage of the CPU # TYPE system_cpu_ctrl_max gauge system_cpu_ctrl_max 25 1719852690061
# HELP system_cpu_ctrl_avg Peak usage of the CPU # TYPE system_cpu_ctrl_avg gauge system_cpu_ctrl_avg 2 1719852690061
# HELP system_memory_all Total # TYPE system_memory_all gauge system_memory_all 172928 1719852690061
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.
Switching phone systems doesn’t have to mean rebuilding everything from scratch. The Vodia PBX migration tool imports key configuration data from backups, including extensions, ring groups, queues, desk phones, and basic auto-attendant settings. Built into the Vodia Admin Portal, it guides administrators through the import process and reduces repetitive manual work, whether you’re moving 10 extensions or 1,000. Explore what transfers, what needs manual setup, and how the built-in tool reduces repetitive work when moving to Vodia.
Apps have changed how businesses communicate and work, but every digital experience still depends on physical hardware. From smartphones, desk phones, and headsets to networking equipment and cloud servers, reliable infrastructure supports productivity, security, and call quality. Here’s why hardware still matters in an app-first world and what businesses should consider when choosing dependable devices and secure connectivity for the office, hybrid teams, and remote work, while preparing for evolving technology.
Vodia Wallboards gives supervisors, contact centers, service providers, and operations teams a self-hosted, real-time view of Vodia call queue activity. Monitor waiting, ringing, and active calls; agent availability; service levels; abandoned calls; and queue trends across one or more Vodia PBX systems. Start with a ready-made layout or build a custom wallboard using queue filters, live widgets, AI summaries, and alerts. Display the information your teams need in a browser, on an operations dashboard, or on a dedicated TV screen.
