Open Group IT4IT Reference Architecture Service Monitoring Component

​Purpose

The Service Monitoring functional component is in charge of creating, running, and managing monitors which measure all aspects/layers of a service such as infrastructure (system and network), application, and security. It is also in charge of storing all measurement results and calculating compound measurements. The Service Monitoring functional component is not in charge of the monitor definitions. These are done earlier in the service lifecycle in the R2D Value Stream and are delivered to Service Monitoring by the Fulfillment Execution functional component in the R2F Value Stream.
