Abstract: A method for inserting application performance management hooks in dynamically linked system libraries in a programming language independent way includes determining a dynamically linked library called by a plurality of applications to transmit and receive messages to and from other applications, and overriding a first method, in the dynamically linked system library, used in transmitting messages to include a transaction identifier in messages transmitted by any of the plurality of applications. The method also includes overriding a second method, in the dynamically linked system library, used in receiving messages to extract the transaction identifier from any messages received by any of the plurality of applications.

Abstract: A method for implementing commands includes storing data defining command operations in a memory. The data defining command operations include a hierarchy of Uniform Resource identifiers (URIs) and Extensible Markup Language (XML) document schema defining XML documents. The method also includes receiving a command request from a remote computer. The command request contains an URI and a Hypertext Transfer Protocol (HTTP) method. Further, the method includes determining a command operation based on the data defining command operations stored in the memory and the command request received, and executing the command operation based on the command request.

Abstract: A method for implementing notifications. The method includes storing data defining notification operations in a memory. The data defining notification operations include a hierarchy of Uniform Resource Identifiers (URIs) and Extensible Markup Language (XML) document schema defining XML documents. The method further includes receiving a notification command including an URI and a Hypertext Transfer Protocol (HTTP) method; determining a notification operation based on the data defining notification operations stored in the memory and the notification command received; and executing the notification operation based on the notification command.
