Using interceptors and out-of-band data to monitor the performance of Java 2 enterprise edition (J2EE) applications

摘要

A method for monitoring performance of a plurality of transactions in a J2EE application server is disclosed. The transactions include a top level transaction and plurality of transactions relating to the top level transaction in a child parent hierarchy. For each of selected ones of said transactions, the method comprises instrumenting the transaction at run-time without modifying its source code to obtain a performance metric corresponding thereto. Further, for each of said instrumented transactions, a correlator is generated for identifying the top level transaction and a parent, if any, of the transaction. The method further calls for utilizing the correlators to cross-correlate a performance metric corresponding to a parent transaction with one or more performance metrics corresponding to one or more child transactions of said parent transaction.
