How To Add Message Tracking to the EDK Gateway

The Exchange Development Kit (EDK) sample gateway can be modified to log tracking information for messages processed. There are three functions that are included in the \Mssdk\Include\EDKTrack.lib that can be used to add tracking functionality.

Following are the functions:

• HrTrackInitLog - This function opens the gateway event tracking module.
• HrTrackUninitLog - This function closes the gateway event tracking module.
• HrTrackWriteLog - This function logs a gateway tracking event.

The Platform SDK and Microsoft Developer Network (MSDN) include a sample console application TRACK that demonstrates how to use these functions to log tracking information to the file \Exchsrvr\Traking.log\Yyyymmdd.log. The sample is a standalone program that does not require a gateway to run. It does not actually track any messages. It does, however, demonstrate how to use these three functions to write tracking information to a file.

When you run the sample TRACK program, you will be required to enter in a valid event type. Valid event types are listed here and defined in the file \Mssdk\Include\RpcPub.h:



The following is an example of the log entered for a message sent from an Exchange User, "User1," to two EDK recipients, "EDKUser1" and "EDKUser2." The priority is 3, mts-id = 1111-11111, gateway name is SGW, remote system is "REMOTE", priority = 1, length is 20, cost = 3,subject mts-id = 2222-22222, and number of recipients = 2:
