WTS Sessions Plug-In - technical Reference
Introduction
The WTS Sessions plug-in provides a view of the current processes running on the machine, which stem from a remote login. This view is updated in real-time and can be configured to display an additional set of metrics to monitor, and also shows a summary of the current sessions at the top of the view. The Geneos Rule Manager can then be used to set up a rule that would change state and trigger an event when these metrics rise above a set level.
Views (for a single view)

Headline Legend
Name | Description |
---|---|

Table Legend
Name | Description |
---|---|
SessionID | The session identifier as used by Windows Terminal Server. |
SessionState | The current state of the session. |
UserName | The name of the user logged in for the session. |
ClientID | The client identifier, typically showing the transport method used for the connection. |
ClientIP | The IP address of the remote client, or "Local" if the session is connecting from the same machine as the server. |
% Processor Time | The percentage processor time that the session is consuming. |
<user defined> | Other columns as specified in the sampler manager, using the "Counters" parameter. |
Actions
View Processes
When selected, the View Processes context-menu option will display a summary window detailing all the processes running for this particular session. The headings displayed in this summary include the following by default:
- ProcessName
- ProcessID
- Creating Process ID
- % Processor Time
- % User Time
- % Privileged Time
- Page Faults/sec
- Working Set
If a WTS Processes plug-in is running, then the headings displayed will show the first three headings above, followed by any user specified headings the WTS Processes plug-in is configured with.
Examples of this functionality are shown below:
Send Message
When selected, the Send Message context-menu option will bring up a dialog asking the user to type in the message to send. After the message is typed, clicking "OK" will send the message to the user machine, where it appears as a standard Windows message dialog. Clicking "Cancel" will of course cancel this operation.
The title of this dialog defaults to "Admin Message", but can be configured with the parameter messageTitle.
Examples of this functionality are shown below:
Logoff Session
When selected, the Logoff Session context-menu option will bring up a dialog asking the user to confirm the logoff. Clicking "OK" will then instruct Windows Terminal Server to end this session, logging off the user and then terminating all running processes. As such, it is recommended that for active sessions the user first use the "Send Message" menu option to send prior warning to give the remote user a chance to save their work. Clicking "Cancel" on the confirmation dialog will cancel this operation.
After this operation is selected, the view will be automatically refreshed. The recently closed session will typically have a state displayed as "Down" to indicate that this session is no longer in operation, but is still in the process of being cleared up.
Examples of this functionality are shown below:
Ping
When selected pings a client logged on to the terminal server. Right click their name and select ping.
Examples of this functionality are shown below:
Traceroute
When selected traces the route to a client logged on to the terminal server. Right click their name and select traceroute.
Examples of this functionality are shown below:
Event Logging
Event logging is switched on by default and captures all events; this includes Logons, Logoffs, active, disconnected and other states. The states are only monitored after the first sample. It is possible to disable event logging by setting disableEvents to true.
Examples of this functionality are shown below:
Plug-In Configuration
The Netprobe that contains this plug-in is called netprobent+wrs. It must run on a machine running the Terminal Services service and the Terminal Services Session performance counters are enabled.
The following parameters can be configured for this plug-in:
counters > counter
A list of metrics to monitor for each process. These will be added to the view as columns at the right-hand side.
