A technique for flexibly adding instrumentation to an application. A file is created which includes a dynamic parameter syntax. The file identifies a trace point in the application, such as a method, and the syntax includes one or more parameters which are evaluated when the method is invoked. The parameters can be used to provide cross-process correlation and/or performance metrics. A client process which calls a server process can include the parameter in a message header according to any desired transport protocol, such as HTTP or JMS. Different application protocols and implementation can be accommodated to track a transaction which executes on different platforms. The dynamic parameter syntax is interpreted as uncompiled code and is designed to be added by the user in the field to augment a package of pre-built instrumentation software after the package has been deployed.

Instrumenting an application with flexible tracers to provide correlation data and metrics

In one embodiment, a method for generating one or more synthetic transactions with one or more web service operations includes accessing a Web Services Description Language (WSDL) file describing a web service and, according to the WSDL file, generating a symbol table for describing a client for generating one or more synthetic transactions with the web service. The method also includes receiving input from a user specifying one or more operations of the web service for invocation, an order for invoking the operations of the web service, and one or more values of one or more parameters of the operations. The method also includes incorporating the input from the user into the symbol table and generating the client according to the symbol table.
