Which are the different data sources from where the Application Performance Monitoring (APM) Java agent can collect spans and metrics data?

The Oracle Cloud Infrastructure (OCI) Application Performance Monitoring (APM) Java agent collects spans and metrics data from multiple sources. It is deployed on Java application servers such as WebLogic, Tomcat, and JBoss, where it instruments the JVM to capture spans, traces, and metrics from running Java applications. Additionally, the APM Java agent can acquire trace data from open-source tracing systems, specifically Jaeger and Zipkin, allowing existing distributed-tracing instrumentation to be forwarded into OCI APM. These two categories (supported Java application servers and open-source tracing frameworks) are the officially documented data sources from which the APM Java agent gathers spans and metrics.

A. NginX — NginX is a web/reverse-proxy server, not a Java application server; it is not a data source for the APM Java agent.
D. VMware ESXi — ESXi is a hypervisor for infrastructure virtualization and is unrelated to Java application-level span/metric collection by the APM Java agent.
