Virtual Desktop Sessions Details Test

A user logged into a virtual desktop does not imply active usage of that desktop. In a VDI infrastructure, it is common for users to just log into desktops, and leave them unused for long time periods. Such desktops are a huge resource drain, as they continue to consume resources, regardless of the level of activity on them. Idle users themselves are unproductive resources. Besides, since these users unnecessarily hold on to desktops, users with genuine needs may not have any desktops to work with. If administrators can quickly identify these idle users and the desktops they are logged into, they can rapidly pull the desktops from such users and assign them to users who can use them effectively. The Virtual Desktop Sessions Details test turns the spotlight on these idle users. For each user session on a Windows virtual desktop (on the cloud), this test reports the total duration of the session and the percentage of time for which the session was active. The test also reports the total idle time during the session. From these statistics, administrators can accurately identify those users who are wasting the desktops assigned and resources allocated to them.

Target of the test : A Windows virtual desktop on the cloud

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every user who is currently logged into a Windows virtual desktop on the cloud.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The nick name of the Cloud Desktops component for which this test is to be configured.

Port

Refers to the port at which the specified host listens to. By default, this is NULL.

Inside View Using

To obtain the 'inside view' of performance of the cloud-hosted Windows desktops - i.e., to measure the internal performance of the Windows virtual desktops - this test uses a light-weight eG VM Agent software deployed on each of the desktops. Accordingly, this parameter is by default set to eG VM Agent (Windows).

Report Powered OS

This flag is relevant only for those tests that are mapped to the Inside View of Desktops layer. If this flag is set to Yes (which is the default setting), then the 'inside view' tests will report measures for even those Windows virtual desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_virtualdesktopname. On the other hand, if this flag is set to No, then this test will not report measures for those Windows virtual desktops to which no users are logged in currently.  

Is Cloud VMs

Since this test runs for a 'Cloud Desktops' component, this flag is set to Yes by default.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total time in session

Indicates the time that has elapsed since this user logged into this desktop.

Mins

 

Active time in last measure period

Indicates the percentage of time in the last measurement period during which this user actively used this desktop.

Percent

Ideally, the value of this measure should be 100%.

A low value for this measure denotes a high level of inactivity recently.

Time since last activity

Indicates the time that has elapsed since this user performed an action on this desktop.

Mins

A high value for this measure indicates that the user has been idle for a long time. Compare the value of this measure across users to know which user has been idle for the longest time.

Total idle time in session

Indicates the total time for which this user was idle during the session.

Mins

If the value of this measure is the same as the value of the Total time in session measure for a user, it means that the user has been idle throughout the session.

If the value of this measure is close to the value of the Total time in session measure for a user, it implies that the user has been idle for a long time.

If the value of this measure is much lesser than the value of the Total time in session measure for a user, it means that the user has been active for most part of the session.
