Hyper-V Logins Test

This test monitors the user logins to guests and reports the total count of logins and logouts.

Target of the test : A Hyper-V server

Agent executing the test : An internal agent

Output of the test : One set of results for every user or guest or useronguest to the Hyper-V server monitored

Configurable parameters for the test
  1. Test period - How often should the test be executed
  2. Host - The host for which the test is to be configured.
  3. port - The port at which the host listens. By default, this is NULL.
  4. inside view using - By default, this test communicates with every VM remotely and extracts “inside view” metrics. Therefore, by default, the inside view using flag is set to Remote connection to VM (Windows).

    Typically, to establish this remote connection, eG Enterprise requires that the eG agent be configured with domain administrator privileges. In high-security environments, where the IT staff might have reservations about exposing the credentials of their domain administrators, this approach to extracting “inside view” metrics might not be preferred. In such environments therefore, eG Enterprise provides administrators the option to deploy a piece of software called the eG VM Agent on every Windows VM; this VM agent allows the eG agent to collect “inside view” metrics from the Windows VMs without domain administrator rights. Refer to Configuring Windows Virtual Machines to Support theInside View Using the eG VM Agent for more details on the eG VM Agent. To ensure that the “inside view” of Windows VMs is obtained using the eG VM Agent, set the inside view using flag to eG VM Agent (Windows). Once this is done, you can set the domain, admin user, and admin password parameters to none.

  5. domain, admin user, admin password, and confirm password – By default, this test connects to each virtual guest remotely and attempts to collect “inside view” metrics. Accordingly, the inside view using flag is set to Remote connection to VM (Windows) by default. To obtain a remote connection, the test must be configured with the privileges of an administrative user to the domain within which the guests reside. The first step towards this is to specify the DOMAIN within which the virtual guests reside. The admin user and admin password will change according to the domain specification. Discussed below are the different values that the domain parameter can take, and how they impact the admin user and admin password specifications:

    • If the VMs belong to a single domain:  If the guests belong to a specific domain, then specify the name of that domain against the domain parameter. In this case, any administrative user in that domain will have remote access to all the virtual guests. Therefore, an administrator account in the given domain can be provided in the ADMIN USER field and the corresponding password in the ADMIN PASSWORD field. Confirm the password by retyping it in the CONFIRM PASSWORD text box.
    • If the VMs belong to different domains: In this case, you might want to provide multiple domain names. If this is done, then, to access the guests in every configured domain, the test should be configured with the required user privileges; this implies that along with multiple DOMAIN names, multiple ADMIN USER names and ADMIN PASSWORDs would also have to be provided. 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 VM Monitoring.
    • If the inside view using flag is set to ‘eG VM Agent (Windows)’: On the other hand, if the inside view using flag is set to eG VM Agent (Windows), then it implies that the inside view can be obtained without domain administrator privileges. Therefore, set the domain, admin user, and admin password parameters to none.
  6. REPORT BY USER – For the Hyper-V monitoring model, the REPORT BY USER flag is set to NO by default, indicating that by default, the guest operating systems on the Hyper-V server are identified using the hostname specified in the operating system. On the other hand, for the Hyper-V VDI model, this flag is set to YES by default; this implies that in case of VDI servers, by default, the guests will be identified using the login of the user who is accessing the guest OS. In other words, in VDI environments, this test will, by default, report measures for every username_on_virtualmachinename.
  7. DD FREQUENCY - Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For a Microsoft Hyper-V server, this is set to 1:1 by default. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. It is recommended that you do not change the default setting of this parameter. This is because, eG Enterprise can discover the IP addresses of the guest operating systems on a Hyper-V host, only while generating the detailed measures for this test. The automatic discovery of the guest IPs, in turn, enables eG Enterprise to perform AutoVirtualMapping.
  8. 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

Current sessions

Indicates the number of user sessions that are currently active across all guests


This is a good indicator of the session load on the guests.

New logins

Indicates the number of new logins to the guests.


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

Percentage of new logins

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



Sessions logging out

Indicates the number of sessions that logged out.


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.
