One-Way Connectors

  • Article

A one-way connector manages the flow of alerts and other data from MOM to another program, but it does not send alerts or other data from the other application back to MOM. MOM alerts are sent only once after they are initially created. If the alert is modified in MOM, usually the connector will not send the alert again. The system receiving the alert assumes all responsibility for updating and managing the alert's state and properties after it is forwarded.

There are two types of one-way connectors, based on how the connector is implemented:

  • Rule-based one-way connectors
  • Application-based one-way connectors

If the one-way connector is only sending alert data to another program, and there is no need to update the original MOM alert at a later time, a separate connector application or service might not be necessary. A MOM alert rule can be used to filter the alerts that need to be forwarded.

For all alerts that match the filtering criteria, the alert rule can run a response, such as a script response, that communicates the MOM alert information directly to the other program through the APIs or data that the management program exposes.

For one-way connectors where direct communication between a script and the application is not possible, several options exist. A custom COM wrapper can be created to help make calls to the other management system from MOM script responses. MOM can also be configured to send an SNMP trap instead of the script response, provided that the other system supports SNMP.

The following illustration shows the sequence of steps performed by a typical one-way connector application as it collects and forwards MOM data.

For one-way and two-way connector applications, the process of accessing data from MOM and sending it to the other system will be very similar. For more information about getting event and alert data from MOM, see Collecting MOM Data.
