Stack Serverless Observability APM Agent PHP
The Elastic APM PHP Agent measures the performance of your application and tracks errors. It is an extension that must be installed in your PHP environment.
APM Agents work in conjunction with the APM Server, Elasticsearch, and Kibana. The APM Guide provides details on how these components work together, and provides a matrix outlining Agent and Server compatibility.
