Notification Manager OMVS¶

The Notification Manager Open Metadata View Services (OMVS) is a REST API designed to support the management of resource monitoring, the maintenance of the list of subscribers to that monitoring, and the notification of significant events or situations to the registered subscribers.

Examples of events that could trigger a notification include:

• The creation, update or delete of specific metadata elements.
• The creation, update or delete of specific types of metadata elements.
• The detection of an unauthorized user action.
• The completion of a process.
• The production of a particular type of audit log record.
• A timer expiring.

When the specific notification occurs, the resulting action could be:

• To create a user notification
• To create a ToDo for a user
• To initiate a governance action process
• To create an incident report
• To create an event on a specific topic
• To call a remote API

Notification Types¶

The notification definitions are stored in Open Metadata using Notification Types. Attached to the notification type are the resources to monitor and the subscribers to be notified if/when significant event happens around the monitored resources. Subscribers are typically actors or automated processes.

Egeria supports a number of monitoring agents called watchdog action services that are able to support the monitoring of open metadata events and subscribers that are either actors or governance actions.

The Notification Manager OMVS supports search, create, update, and delete of the following types of open metadata that supports notifications.

• Notification Types
• Subscribers
• Monitored Resources

It may be used by a subscriber wishing to change their subscriptions, or an external monitor that is using the Open Metadata definitions to configure its monitoring and notification processes.
