Java and Java Profile sensor releases

Instana monitors your Java environment by using the Java sensor, tracer, and profiler.

The Instana Java sensor provides infrastructure metrics across your environment. Instana Java Tracer provides automated code instrumentation and end-to-end traces of requests, while the Java profiler analyzes code-level performance and discovers bottlenecks in production code. For more information, see Monitoring Java virtual machine and Java Tracer releases.
