Virtual Desktop Disconnects in Controllers Test

This test reports the total number of disconnected sessions to the desktops managed by the monitored Xen DDC, and also automatically restarts/shuts down the virtual desktop, if the disconnected session duration to that desktop exceeds a configured value.

Target of the test : A Citrix Delivery Controller v3/4

Agent deploying the test : An internal agent

Outputs of the test : One set of results for the Delivery Controller 3/4 being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which this test is to be configured.

Port

Refers to the port at which the specified host listens to.

Admin User and Admin Password

If you want the test to automatically reboot/shut down virtual desktops if the duration of disconnected sessions to the desktops exceeds a configured value, then you first need to grant the test the privilege to access the desktops. For this purpose, in the Admin User and Admin password text boxes, provide the credentials of a user with administrative privileges to the hosting provider (VC or XenServer) of the desktops. If the test needs to monitor session disconnects across multiple hosting providers, then multiple admin users and admin passwords need to be provided – one for every hosting provider. To help administrators provide these user details quickly and easily, the eG administrative interface embeds a special configuration page. To access this page, simply click on the Click here hyperlink that appears just above the parameters of this test in the test configuration page. To know how to use the special page, refer to Configuring users for disconnected sessions monitoring of this document.

By default, these parameters are set to none; this indicates that the test is not authorized to reboot/shut down desktops by default.

VD Action Duration

The test will automatically reboot/shut down virtual desktops, if the disconnected session duration (in minutes) specified here is violated.

Is VD Reboot

Set this flag to True if the test needs to restart the desktop if the configured VD Action Duration is exceeded. By default, this flag is set to False.

Is VD Shut Down

Set this flag to True if the test needs to shut down the desktop if the configured VD Action Duration is exceeded. By default, this flag is set to False.

Note:

Note that only one of the two flags – Is VD Reboot and Is VD Shut Down – can be set to True at any given point in time. If both are set to False, then the test will neither reboot nor shut down any virtual desktops. If one flag is set to True, but the Admin User and Admin password text boxes are configured with none, then again the test will neither reboot nor shut down any virtual desktops. 

Reconnect Duration

This parameter is used by the test while computing the value for the Quick reconnects by users measure. This measure counts all the users who reconnected to the virtual desktops within the short period of time (in minutes) specified against Reconnect Duration.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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

Total disconnected sessions

Indicates the total number of sessions that are in the disconnected state.

Number

The detailed diagnosis for this measure provides the complete details of disconnected sessions on the virtual desktops managed by the Xen DDC.

New disconnects

Indicates the number of sessions that were disconnected in the last measurement period

Number

The detailed diagnosis for this measure can be used to track whether specific users are being disconnected often.

Quick reconnects by users

Indicates the number of users who reconnected soon after a disconnect.

 

Number

The detailed diagnosis of this measure, if enabled lists the users who have reconnected quickly. 

Successful restarts /shut downs

Indicates the number of virtual desktops that were shut down/restarted successfully by this test.

Number

These measures will appear only if the following conditions are fulfilled:

  • If the Admin User and Admin Password are not set to ‘none’.
  • If either the Is VD Reboot or Is VD Shut down flag is set to True.

Failed restarts / shut downs

Indicates the number of virtual desktops that could not be restarted/ shut down by this test.
