Performance monitoring infrastructure (PMI) for resource adapters:

The Performance Monitoring Infrastructure (PMI) is the underlying framework in

WebSphereApplication Server that gathers performance data from various runtime

resources such as adapters.

The purpose of monitoring is to observe the progress of execution of WebSphere

Business Integration applications, and the WebSphereBusiness Integration system

itself, and publish the results of this observation. By using Performance Monitoring

Infrastructure (PMI), you can observe the progress of adapters running in the

server runtime environment and other business integration applications, and

publish the results. PMI collects data, such as average response time and total

number of requests, from various components in the server,and organizes the data

into a tree structure. Youcan observe data through the Tivoli Performance Viewer,

a graphical monitoring tool that is included with WebSphereApplication Server..

Youcan monitor the performance of the adapters by having PMI collect data at the

following points:

vInboundEventRetrieval:

Will monitor performance of retrieving events fromthe EIS. It enables

monitoring of entering, exiting, failing of the EventManager.getEvents() method.

vInboundEventDelivery:

Will monitor the performance when resourceadapter deliver data to the

endpoint, which conveys changes in or general information from the EIS. It

enables monitoring of entering, exiting, failing of the EventSender.doSendEvent()

method.

vOutbound:

Will monitor the performance of outbound processing of a resourceadapter. It

enables monitoring of entering, exiting, failing of the WBIInteraction.execute()

method.

Extending PMI on WebSphere Process Server:

Toadd a user-defined element or method into the list of monitorable components

you need to modify code and schema files.
