A mechanism is provided for just-in-time instrumentation that uses bytecode insertion to modify a class definition to store a reference to the static class information to be used by probes. A hook is inserted to provide a callback to one or more probes. When the bytecode inserted hook is executed, the static class information is used to locate and execute the application probes.

Process and implementation for using byte code insertion to modify a class definition to define and use probes for application components

A system or method which accesses or otherwise receives collected performance data for at least one server application, where the server application is capable of performing a plurality of transactions with client devices and the client devices are geographically dispersed from the server in known geographical locales, which automatically determines from the performance data which of the transactions are utilized by users of the client devices, which selects utilized transactions according to at least one pre-determined selection criteria, which automatically generates a transaction playback script for each of the selected transactions substituting test information in place of user-supplied or user-unique information in the transactions, which designates each script for execution from a geographical locale corresponding to the locale of the clients which execute the utilized transactions, which deploys the playback scripts to robotic agents geographically co-located with client devices according to the locale designation, and which executes the playback scripts.

The present invention addresses the problem of linking cross-process and cross-thread subtransactions into a single user transaction. The mechanism of the present invention employs bytecode inserted probes to dynamically detect out of process correlating tokens in an inbound request. The bytecode inserted probes retrieve the correlating token in the inbound request. Based on the correlating token retrieved, the bytecode inserted probes are then used to dynamically determine if the inbound user request should be recorded and linked to a transaction that began in another thread or process.

A computer implemented method, data processing system, and computer program product for automating processes using data driven pre-recorded transactions. A process server comprising process modeling tools creates workflows comprising activities linked together based on a set of rules. A test script server connected to one or more activities in a workflow receives requests from the one or more activities to automate an activity. A remote test script agent connected to the test script server receives instructions from the test script server to play back a robotic test script of the activity, wherein the robotic test script is driven by a set of input parameters obtained from recording the activity, and wherein the robotic test script interacts with an application under test to perform the activity as an automated task.

Method and implementation for automating processes using data driven pre-recorded transactions

A system, method, and computer program for dynamically changing the weightings used by a workload distribution program to distribute Enterprise JavaBeans among a group of application servers handling EJBs. The changes are made in response to real-time measurements of the performance of EJBs involved in e-business transactions based on the dynamic insertion of monitors within the EJBs to measure their class and method performance from within the J2EE server. The performance data can be tracked for specific users or specific types of transactions, so that the servers are weighted for optimal handling of the most critical EJBs.

System for autonomically improving performance of Enterprise Java Beans through dynamic workload management

A method and system for exposing monitoring violations to monitored applications is provided. A monitored application may detect that a monitoring application has been applied to monitor a transaction. Based on a defined policy or a threshold within policy, the monitored application may determine if the transaction is in a violation state. If the transaction is in a violation state, the mechanism of the present invention enables the monitoring application to notify the monitored application, such that the monitored application may take corrective action to correct the violation.

Method and apparatus for exposing monitoring violations to the monitored application

A system and method to allow an individual transaction in an instrumented software application to be monitored according to its own configuration. In one preferred embodiment, each transaction is associated with a token. The token includes the monitoring configuration that should be used for the associated transaction. When the application entry point is reached for the transaction, the token is looked up and retrieved, and the monitoring policy configuration of the token determines what data is gathered about the transaction.

Intelligent performance monitoring based on user transactions

A method of enabling transaction probes used to monitor a transaction or modify a primary application handling the transaction. The method begins with retrieving a token associated with the transaction. The token contains information regarding which transaction probes from a plurality of transaction probes will be enabled with respect to the transaction. The token is then read to determine the set of transaction probes from the plurality of transaction probes that will be enabled. The determined set of transaction probes is then enabled.

Enabling and disabling byte code inserted probes based on transaction monitoring tokens

Mechanisms for graph manipulation of transactional performance data are provided in order to identify and emphasize root causes of electronic business system transaction processing performance problems. A system transaction monitoring system, such as IBM Tivoli Monitoring for Transaction Performance&#x2122; (ITMTP) system, is utilized to obtain transaction performance data for a system. This transaction performance data is stored in a database and is utilized to present a graph of a given transaction or transactions. Having generated a graph of the transaction, and having identified problem conditions in the processing of the transaction(s), the present invention provides mechanisms for performing graph manipulation operations to best depict the root cause of the problems.
