Which extension is used for monitoring a Java application exposing MBeans?

The JMX extensions are specifically designed for monitoring Java applications that expose MBeans (Managed Beans). MBeans are a key component of the Java Management Extensions (JMX) technology, which provides a way to manage and monitor Java applications.

By using JMX extensions, Dynatrace can connect to Java applications through JMX and collect performance metrics, monitor application health, and analyze resource usage. This integration is critical for obtaining real-time insights into the performance of Java applications, making it easier to troubleshoot and optimize them.

Other types of extensions, like ActiveGate extensions, may serve different purposes such as securing data gathering or facilitating communication between Dynatrace and various environments. Container extensions are focused on monitoring containerized applications, while memory extensions would be concerned with memory usage metrics rather than specific interaction with Java's MBean architecture.
