Abstract: A system is provided for tracing end-to-end transactions. The system uses bytecode instrumentation and a dynamically injected agent to gather web server side tracing data, and a browser agent which is injected into browser content to instrument browser content and to capture tracing data about browser side activities. Requests sent during monitored browser activities are tagged with correlation data. On the web server side, this correlation information is transferred to tracing data that describes handling of the request. This tracing data is sent to an analysis server which creates tracing information which describes the server side execution of the transaction and which is tagged with the correlation data allowing the identification of the causing browser side activity.

Abstract: The presented enhancement of a rule based instrumentation system taking object oriented inheritance relationships into account is directed to the detection and extraction to inheritance relationships relevant for the instrumentation process. Relevant inheritance relationships which have an impact on the instrumentation process and typically only represent a small fraction of the complete inheritance relationships of a monitored application. The small size of the relevant inheritance relationships allows, for example to prepare it in advance and ship it as part of a monitoring application or to transmit inheritance information between different local instrumentation engines being part of a distributed instrumentation system.

Abstract: A performance management tool is provided that monitors performance in a computing infrastructure in a computing environment. The performance management tool includes a service model that represents the computing infrastructure. The service model is a hierarchical tree structure comprised of a plurality of linked nodes, where each node in the tree structure represents a component of the computing infrastructure and has one or more properties of the component assigned thereto. Each node further includes an inheritance rule which defines how properties assigned to other nodes are inherited by the component. A dimension indexer module is configured to receive a request for properties associated with a particular node and operates to retrieve properties for the particular node from the tree structure, including at least one property not assigned to the particular node but inherited from another node in the tree structure in accordance with the inheritance rule assigned the particular node.
