Documentation forAppOptics
AppOptics will reach its End of Service Life on September 30, 2025. Migrate to the next generation APM solution before September 30. See FAQ, or contact appopticsng-questions@solarwinds.com for support. Documentation is no longer being updated, and some features or links may not work as described.

PHP Agent (legacy)

The following content pertains to the legacy AppOptics PHP Agent.

AppOptics agents are no long receiving updates. The new SolarWinds Observability libraries are regularly updated with new features and improvements. If you are still relying on the AppOptics agents and your components are supported by the new libraries, consider migrating to SolarWinds Observability.

If you have already transitioned to the new SolarWinds Observability PHP Library, see the SolarWinds PHP Library documentation for information.

SolarWinds Observability libraries are not compatible with AppOptics agents. Do not use a mix of SolarWinds Observability libraries and AppOptics agents to instrument applications that are part of a distributed trace.

The PHP agent provides automatic tracing and metrics for PHP-based applications, covering a variety of popular frameworks and libraries out of the box. For new features, fixed issues, and updated components, see the PHP Agent (legacy) Release Notes.

Get started

Ensure that your platform and application components are supported.

To get up and running with APM, you'll install the AppOptics PHP extension. After that, a restart of your web server or PHP process will load the agent and automatically begin reporting data.

Custom Instrumentation

Custom instrumentation can be used to get extra application-specific visibility in AppOptics, both adding custom spans for distributed tracing and adding custom timers/counters for metric reporting and alerting. Check out the SDK.

Code Profiling

Code profiling provides extra insight into code level execution time that is otherwise not captured by auto-instrumentation. See code profiling and the PHP-specific details for more on this feature, available starting with agent version 3.4.0.

Navigation Notice: When the APM Integrated Experience is enabled, AppOptics shares a common navigation and enhanced feature set with other integrated experience products. How you navigate AppOptics and access its features may vary from these instructions.
