System for instrumenting resources utilizing WS-management resource MBean wrappers for JAXB beans
An approach is provided in embodiments of the present invention for utilizing Java™ Management Extensions (JMX) as a back end to “instrument” (i.e. monitor and control) computer system resources, including servers, devices, and applications etc., within standard resource management model(s) that are external to Java™. For example, JMX can be used as a back end to instrument WS-Management resources—in particular, JMX MBeans can be used to implement Common Information Model (CIM) WS-Management resources.
1. A system for instrumenting a system resource, comprising:
a management application coupled to a network, wherein the management application is capable of generating a request associated with a standard management operation or a resource-specific action for managing the system resource, wherein the system resource is derived at least in part from a Common Information Model (CIM) and wherein the request is a WS-Management (Web Services-Management) request;
an adaptor coupled to the network, wherein the adaptor is capable of answering the request to perform the standard management operation or the resource-specific action on the system resource by utilizing a Java API for XML Binding (JAXB) generated Extensible Markup Language (XML)-serializable Java bean to instrument the system resource as an MBean, wherein the MBean is generated from a plurality of JAXB-serializable Java beans including a first JAXB-serializable Java bean, a second JAXB-serializable Java bean, and a third JAXB-serializable Java bean and wherein the plurality of JAXB-serializable Java beans are generated utilizing a JAXB compiler;
a servlet included in the adaptor, wherein the servlet is capable of receiving the request from the management application via the network; and
a processor capable of receiving the request from the servlet and responding to the request by invoking the MBean to perform the standard management operation or the resource-specific action on the system resource, wherein the management application, the adaptor, and the processor are comprised of instructions which are executed by a computer.
2. The system as recited in claim 1 , wherein the request is a Java Management Extensions (JMX) request.
3. The system as recited in claim 1 , wherein the processor creates an object that is capable of creating a proxy for invoking the MBean.
4. The system as recited in claim 3 , wherein the proxy is a WSManResourceInvoker proxy.
5. The system as recited in claim 1 , wherein an instance of the MBean is capable of:
exposing properties of the first JAXB-serializable Java bean as MBean attributes,
utilizing an instance of the first JAXB-serializable Java bean to answer the standard management operation associated with the system resource, and
utilizing an instance of the second JAXB-serializable Java bean to transport input parameters associated with the resource-specific action defined for the system resource or
utilizing an instance of the third JAXB-serializable Java bean to respond to return an output of the resource-specific action.
6. The system as recited in claim 1 , wherein the standard management operation is a WS-Management (Web Services-Management) operation.
7. The system as recited in claim 6 , wherein the WS-Management operation is a Get, a Put, a Create, a Delete, a Notifications, or a WS-Transfer Fragment Utilizing XPath operation.
8. The system as recited in claim 1 , wherein the resource-specific action is a custom WS-Management action.
9. A computer-readablemedia for directing a computer system to instrument a system resource, the computer-readable media being non-transitory and comprising:
instructions for providing an adaptor coupled to a network, wherein the adaptor is capable of answering a request from a management application to perform an standard management operation or a resource-specific action on the system resource, wherein the system resource is derived at least in part from a Common Information Model (CIM) and the request is a WS-Management (Web Services-Management) request;
instructions for performing the standard management operation or the resource-specific action on the system resource by utilizing a Java API for XML Binding (JAXB) generated Extensible Markup Language (XML)-serializable Java bean to instrument the system resource as an MBean, wherein the MBean is generated from a plurality of JAXB-serializable Java beans including a first JAXB-serializable Java bean, a second JAXB-serializable Java bean, and a third JAXB-serializable Java bean and wherein the plurality of JAXB-serializable Java beans are generated utilizing a JAXB compiler;
instructions for including a servlet in the adaptor, wherein the servlet is capable of receiving the request from a management application via the network; and
instructions for providing a processor, wherein the processor is capable of receiving the request from the servlet and responding to the request by invoking the MBean to perform the standard management operation or the resource-specific action on the system resource, wherein each of the instructions is executed by a computer.
