  • Supports a wide range of integrations, including PHP-FPM.
  • Lightweight and easy to install.

Getting Started:

  1. Install Netdata on your server.
  2. Access the Netdata dashboard to view real-time metrics.
  3. Customize and configure alerts based on your PHP application’s metrics.

5. Zabbix:

Zabbix is an open source monitoring solution known for its versatility. While commonly used for server and network monitoring, Zabbix can be configured to monitor PHP applications by collecting metrics and generating alerts based on predefined thresholds.


  • Extensive support for monitoring diverse environments.
  • Customizable alerting and notification mechanisms.
  • Web-based interface for configuring and visualizing monitored data.

Getting Started:

  1. Install and configure the Zabbix server.
  2. Set up a Zabbix agent on your PHP server to collect metrics.
  3. Create custom items, triggers, and dashboards for monitoring PHP application metrics.


Open source PHP application monitoring tools empower developers to gain valuable insights into the performance, health, and behavior of their applications. Whether focusing on metrics collection, visualization, or profiling, these tools offer a range of features to meet the diverse monitoring needs of PHP developers. Choosing the right combination of tools based on your specific requirements can significantly enhance your ability to optimize and maintain the health of PHP applications.
