Java Tracer
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 tracing data, while the Java profiler analyzes code-level performance and discovers bottlenecks in production code. For more information, see Monitoring Java virtual machine. To get specific tracer updates, you need to install the associated agent version specified in the release version.
