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

Compressing transaction data is provided. A current transaction data point is received. A determination is made as to whether the current transaction data point is a first transaction data point or a subsequent transaction data point of a set of transaction data points for a current variable length aggregation record. A further determination is made as to whether the subsequent transaction data point is within a predetermined tolerance of a predicted transaction data point in response to the current transaction data point being the subsequent transaction data point. The subsequent transaction data point is compressed into the current variable length aggregation record in response to the subsequent transaction data point falling within the predetermined tolerance of the predicted transaction data point.

Compress transaction data using serial micro-trends

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

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.

Process and implementation for dynamically determining probe enablement using out of process correlating token

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.
