RDS Clients Test

This test measures the client connections to and from a Microsoft RDS server. This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick the Microsoft RDS as the desired Component type, set Performance as the Test type, choose the test from the disabled tests list, and click on the < button to move the test to the ENABLED TESTS list. Finally, click the Update button.

Target of the test : A Microsoft RDS server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every server being monitored

Configurable parameters for the test
Parameters Description

Test period

This indicates how often should the test be executed.


The host for which the test is to be configured.


Refers to the port used by the Microsoft RDS server .


By default, the ServerIP field will display the IP address of the Microsoft RDS server.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Current connections

The number of TCP connections currently established by clients to the Microsoft RDS server


This measure directly indicates the loading on the Microsoft RDS server from clients. Typically one connection is established per active session to the Microsoft RDS server.

New connections

The number of new TCP connections initiated by clients to the Microsoft RDS server during the last measurement period


Tracking the new connections over time can provide an indication of when clients login to the Microsoft RDS server. A spurt of connections and disconnections may be indicative of sporadic failures of the Microsoft RDS server.

Old connections removed

The number of TCP connections that were removed because the clients may have disconnected from the Microsoft RDS server during the last measurement period


A large number of sudden connection drops may be early warning indicators of problems with the Microsoft RDS server.

Avg connection duration

The average time from when a connection is established to when the corresponding connection is disconnected.  The duration of a connection is measured from its start time to the current time. The accuracy of this measurement is limited by the frequency at which this test is run. 


This value can provide an indicator of how long clients stay connected to a Microsoft RDS server. This information together with the number of simultaneous clients can be useful for capacity planning in Microsoft RDS server environments (i.e., how to size the Microsoft RDS server).
