The following diagram shows the JVM Diagnostics Architecture.
The JVM Diagnostics Manager that is present on the WebLogic Server target retrieves historical metric data from the Management Repository (Enterprise Manager Repository). The JVM Diagnostics Agent deployed on the WebLogic Server target, collects real-time data and transmits it to the JVM Diagnostics Manager. The communication between the JVM Diagnostics Manager and Agent can be a secure (SSL) or non-secure connection.
