The Serviceability Group
The Serviceability group is comprised of people interested in the design, implementation, and maintanence of Serviceability components.
Java SE contains several technologies that allow Java programs to be debugged, profiled, monitored and managed. These technologies allow a tool written in the Java programming language to obtain information from the Java Virtual Machine(JVM) in a different process. These technologies typically:
- Contain Java code in the J2SE repository
- Contain native code in the J2SE repository
- Contain native code in the HotSpot repository. This code implements interfaces that are used by the code in the J2SE repository. This typically involves some form of inter-process communication.
In addition, Java SE contains several tools that use these serviceability technologies. The following table shows the technologies that are available and the tools that use them.
||Tools That Use It|
|JPDA-Java Platform Debugger
including JVM TI
|JMX - Java Management Extension||jconsole|
|Monitoring and Management||jconsole|
|Dynamic Attach||jconsole, jdb, jinfo, jmap, jstack|
|jvmstat Performance Counters||jconsole, jstat|
|Serviceability Agent||jdb, jinfo, jmap, jstack|
DocumentationServiceability code resides in both the HotSpot repository and the J2SE repository: The Java Management Extensions (JMX) API for information about JMX.
