HDX Desktop Logins Test

Use this test to determine the current session load on the virtual desktops in your infrastructure. The detailed diagnosis of this test also reveals who launched the sessions, when, from which client, to which server, the session duration, and the overall quality of each user’s session. This way, administrators can quickly identify which user’s experience with virtual desktops is below-par and what is causing it – a flaky network connection? a bandwidth-intensive communication over the network? or a delay at the server-end? The test also tracks session logouts, and points to abnormal logouts.

Target of the test : Citrix NetScaler HDX Insight

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the virtual desktop infrastructure monitored

Configurable parameters for the test
  1. Test period - How often should the test be executed. It is recommended that you set the test period to 5 minutes. This is because, the Nitro API using which the eG agent collects metrics from HDX Insight, is capable of capturing only the performance data related to the last 5 minutes.
  2. Host - The host for which the test is to be configured.
  3. insight username,insight password, and confirm password -  To connect to HDX Insight and collect the metrics it captures, the eG agent needs to be configured with the credentials of a user with read-only permissions to HDX Insight. Type the name of this user against insight username and the password of this user against insight password. Then, confirm the password by retyping it in the confirm password text box.
  4. ssl – By default, HDX Insight is not SSL-enabled. This is why, this flag is set to No by default. If it is SSL-enabled, then change this flag to Yes.
  5. 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.
  6. 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 sessions:

Indicates the number of user sessions that are currently active across all virtual desktops.

Number

This is a good indicator of the session load on the virtual desktops.

To know which users are contributing to the load, use the detailed diagnosis of this measure. The detailed diagnosis additionally reveals when each user logged in, from which client, to which server, the session duration, and the quality of the user’s session. This way, administrators can quickly identify which user’s experience with virtual desktops is below-par and what is causing it – a flaky network connection? a bandwidth-intensive communication over the network? or an authentication delay with the server hosting desktops?

New logins:

Indicates the number of new logins to the virtual desktops.

Number

A consistent zero value could indicate a connection issue.

If this measure reports a non-zero value, use the detailed diagnosis of the measure to know which user logged into which virtual desktop, when.

Percent new logins:

Indicates the percentage of current sessions that logged in during the last measurement period.

Percent

 

 

Sessions logging out:

Indicates the number of sessions that logged out.

Number

If all the current sessions suddenly log out, it indicates a problem condition that requires investigation.

The detailed diagnosis of this measure lists the sessions that logged out. The quality of each user’s session is also revealed. This way, administrators can quickly identify which user’s experience with virtual desktops is below-par and what is causing it – a flaky network connection? a bandwidth-intensive communication over the network? or a delay at the server-end?

To know which users are contributing to the load on the desktops, use the detailed diagnosis of the Current sessions  measure.

The detailed diagnosis of the Sessions logging out measure lists the sessions that logged out. The quality of each user’s session is also revealed. This way, administrators can quickly identify which user’s experience with virtual desktops is below-par and what is causing it – a flaky network connection? a bandwidth-intensive communication over the network? or a delay at the server-end?
