  • Jconsole : The JConsole graphical user interface is a monitoring tool that complies to the Java Management Extensions (JMX) specification.
    JConsole uses the extensive instrumentation of the Java Virtual Machine (Java VM) to provide information about the performance and resource consumption of applications running on the Java platform.
  • Jvisualvm: Java VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM), and for troubleshooting and profiling these applications.

NOTE: Since Jvisualvm is third-party tool, SAP doesn't provide any support when you are going to use it. Please go to Oracle for further assistance.
