State Monitoring Overview

  • Article

State Monitoring indicates whether a managed computer is healthy at a given time. MOM updates the status of managed computers, and then presents the status as part of Status Monitoring view. MOM provides the status of a monitored computer at several levels:

  • Computer group level: provides the status of computers listed directly or indirectly, based on the health of a computer group. The health of the computer group is derived from the health of the computers contained in the computer group.

  • Computer level: provides the status of whether applications (referred as Server Roles) running on the computer are healthy. The health is derived from the health of the hosted applications.

  • Application level (Server Role): provides the overall status of all application instances of the server role. For example, Microsoft SQL Server. health is dependent on all of the SQL instances running on that computer.

  • Application instance level (Server Role Instance): the health of the application instance is derived from the health of different areas of the application instance (referred as "component".)

  • The health of a Component of an application instance is derived by reviewing the non-resolved alerts associated with the component. The status becomes the severity of the most severe, non-resolved alert that has an active problem (problem state).

  • The status of a managed computer is an alert severity value that specifies how severe the problem is within the environment. In the Operator console, the status is mapped to colors (for example, red, yellow, and green) which are associated with the alert severity. The Summary State view in the Operator console shows aggregated information about alerts and their associated entities, such as computer groups, computers, and application instances.

State can only be set by raising alerts through MOM. A red or yellow state alert is a traditional MOM alert that will be visible to operators. A green alert will not be visible to operators, and it is used to clear the state for red or yellow alerts.
