IBM has released a tool that detects delays and hangs in WebSphere(R) trace and HTTP plug-in trace.
WebSphere® Application Server trace is used to obtain detailed information about running components, including application servers, clients, and other processes in the environment, such as the time and sequence of methods called by base classes.
IBM® Trace and Request Analyzer for WebSphere Application Server allows you to find delays and possible hangs from WebSphere trace files and HTTP plug-in traces by parsing call trees of methods and traces and calculating delays in each method and trace.
The package includes a Java™ graphical user interface (GUI) application that displays delays in lists and tables.
