Abstract: A mechanism is provided for customizing communication of correlation data between servers using a custom or proprietary communication protocol. The system may modify a payload transmitted between servers to include monitoring parameters. The payload may be modified by expanding a portion of the payload or otherwise inserting data into the payload. The portion may include a header, footer, an additional property, a field, or other portion of the header. A mechanism may detect both outgoing calls and incoming requests to either modify the request with the payload or retrieve the payload from the request. The configuration preferences received from a user may be used to process the detected calls and modify a payload at a designed portion suitable to be expanded. Once sent, the configuration parameters may be used by a recipient server to detect the request with the modified payload and retrieve the monitoring parameter.
