The PHP agent provides automatic tracing and metrics for PHP-based applications, covering a variety of popular frameworks and libraries out of the box.
Check that your platform is 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 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.
