Two-Way Connectors

A two-way connector manages the flow of data from MOM to another program and sends alerts, events, or other data from the other application back to MOM. Because a separate application is usually responsible for running queries and sending messages, you can perform error-handling and other functions that will improve the reliability of the system, compared to a one-way connector based only on MOM rules.

Developing a two-way connector is more complex than developing a one-way connector. If you require a two-way connector, the Microsoft Connector Framework (MCF) should be used. The MCF provides an implementation for much of the logic that a two-way connector requires.

Two-way connectors require a separate application or service to manage the flow of data from MOM to the other management program. The following illustration shows the sequence of steps performed by a typical two-way connector application to collect and forward MOM data to another management program.

 

After resolving the issue in the help desk program, the original MOM alert can be updated to indicate that the issue has been resolved. The following illustration shows the sequence of steps performed by a typical two-way connector application to update an existing MOM alert.

 

Connectors can also use outside programs as sources of new alerts for MOM. Alerts can be added by using the MOM Connector Framework, or they can be generated by MOM rules as they respond to events or performance data they collect. For more information about adding event data and alerts to MOM, see Sending Data from an Application Back to MOM.

The following illustration shows the sequence of steps performed by a typical two-way connector application as it uses a MOM rule to generate a copy of an alert from another management program.
