How health rolls up
The Remote Desktop Services Management Pack views Remote Desktop Services as a hierarchy. The health of each level depends on the health of the level below it. The top level contains the following: RD Session Host role service, RD Virtualization Host role service, RD Gateway role service, RD Licensing role service, RD Connection Broker role service, and RD Web Access role service. The lowest level monitors for a server's service states, events, and counters. When a number of these monitors changes state, the level above changes state to match; in other words, the health of the lower level rolls up to the level above it.
For example, the state of the RD Session Host server's performance monitors rolls up to the RD Session Host server's overall performance state. In the meantime, the state of the RD Session Host server’s health monitors rolls up to the RD Session Host server's overall availability state. The performance state and the availability state then roll up to set the overall state of the RD Session Host server.
The Remote Desktop Services Computer Role is the highest-level object in the health hierarchy and is hosted as a computer role of the computer object. Below the Remote Desktop Services Computer Role, one or more role service classes exist depending on which of the various role services have been added to the server with the Remote Desktop Services role installed. Each of these role services has its own state that is driven by various monitors, and the state of all these role services is reflected back to the Remote Desktop Services Computer Role.

Viewing information in the Operations Manager Console
After your Remote Desktop Services Management Pack has had time to gather some data, you begin to see monitoring information in the Operations Manager Console. The Microsoft Windows Remote Desktop Services folder contains views that present information about the state, health, and performance of Remote Desktop Services.

Key monitoring scenarios
The Remote Desktop Services Management Pack monitors the availability and performance of the following servers: the RD Session Host server, the Remote Desktop license server, the RD Connection Broker server, the RD Web Access server, the RD Gateway server, and the RD Virtualization Host server. The following table describes the key monitoring scenarios:
| Scenario | Description |
|---|---|
RD Session Host server performance |
Checks the status of the RD Session Host server by using three key performance monitors that are enabled by default: the number of active sessions, the number of inactive sessions, and the total processor time per session. When the number of active sessions approaches the performance limit of the computer's hardware, the monitor changes to a critical health state and alerts you. When a number of inactive sessions exceeds the idle session limit field of either the Remote Desktop Services node in Group Policy or the Remote Desktop Session Host Configuration console, the monitor changes to a critical state and alerts you. When the total processing time per session exceeds 80 percent of the CPU's total capacity for 15 minutes, the monitor changes to a critical state and alerts you. |
RD Session Host server monitoring |
Ensures that the Remote Desktop Services service is running, and tests for connectivity to the Remote Desktop license server and the RD Connection Broker server. It also monitors the number of open sessions and disconnected sessions. |
Remote Desktop license server monitoring |
Ensures that the Remote Desktop Licensing service is running, and that Remote Desktop Services client access licenses (RDS CALs) are installed and available on the Remote Desktop license server. The Remote Desktop Licensing database file is restored when there is a modification to the old database file. |
RD Gateway server monitoring |
Ensures that the Remote Desktop Gateway service is running, and checks that it is able to connect to the RD Session Host server. Monitors the number of current connections. |
RD Connection Broker server monitoring |
Ensures that the Remote Desktop Connection Broker service is running. Monitors the availability and configuration of the RD Web Access role service. |
RD Web Access server monitoring |
Ensures that the RD Web Access server is running. Monitors connectivity between the RD Session Host server and the RD Web Access server. |
Get information about a monitor
By viewing a monitor's product knowledge, you can get information about a monitor and read potential solutions for the problem that it detects.
To view product knowledge for a monitor
In the Operations console, click Authoring.
In the navigation pane, expand Management Pack Objects, and then click Monitors.
In the list of monitors, expand the target that you want until the monitor appears.
Note
To search for a monitor, in the Look for box, type the name of a monitor or words that its name might contain, and then click Find Now.
Right-click the monitor that you want, click Properties, and then click the Product Knowledge tab.
Placing monitored objects in maintenance mode
When a monitored object, such as a computer or distributed application, goes offline for maintenance, Operations Manager 2007 detects that no agent heartbeat is being received and, as a result, might generate numerous alerts and notifications. To prevent alerts and notifications, place the monitored object into maintenance mode. In maintenance mode, the following are suppressed at the agent: alerts, notifications, rules, monitors, automatic responses, state changes, and new alerts.
If a dependent server is in maintenance mode, alerts can still be raised from other Remote Desktop Services role services. For example, if the Remote Desktop license server is put into maintenance mode and is offline, alerts can occur from other servers running Remote Desktop Services role services that fail to get a license from the offline Remote Desktop license server.
For more information about placing a monitored object in maintenance mode, see How to Put a Monitored Object into Maintenance Mode in Operations Manager 2007 on Microsoft TechNet (https://go.microsoft.com/fwlink/?LinkId=108358).
