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