How Health Rolls Up

適用於: Exchange Server, Operations Manager 2007

The Exchange Server 2003 Management Pack views the messaging service as a hierarchy, where each level depends on the objects at the next level to be healthy. The top of this hierarchy is the Exchange Service object, and the lowest levels are the components of an Exchange back-end or front-end server, such as Information Store. When a specified number, defined in the management pack, of the lower level objects change state, the level above them changes state to match. This action is called "rolling up health."

The following illustration is the topology view of an Exchange Service object with one back-end (YUG060D) and one front-end (YUG078D) server.


In this illustration, the health of the Exchange Service is critical, as denoted by the red dot with an X through it. YUG060D is healthy, as denoted by a white dot with a √ (check mark) though it. For the purposes of Exchange Server 2003, this implies all of the Exchange managed objects hosted by YUG060D are healthy. For Exchange, a higher level object can be healthy only if all of its lower level objects are healthy.

YUG078D is in a critical state. Within the box that represents YUG078D, the Exchange ActiveSync (EAS), Outlook Mobile Access (OMA), and Outlook Web Access (OWA) managed objects are in critical states. To check the health of these objects, in the Operations Manager 2007 Operations Console, you can right-click these objects, and then click Health Explorer.

In Health Explorer, you can see the availability, configuration, performance, and security monitors for the object, although not all monitor types are necessarily provided for every object type. By clicking the monitors that are in a critical state, you will be provided with information and actions to help resolve the issue.

The Exchange Topology view is a diagram view. Operations Manager 2007 also provides Alert, Event, State, Performance, Task Status, and Dashboard views to help you better understand the health of your IT environment.
