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
Parameter | Description |
---|---|
Test period |
This indicates how often should the test be executed. |
Host |
Specify the HOST for which this test is to be configured. |
Port |
Specify the port at which the target host is listening. By default, this is NULL |
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 topic 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. |
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:

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. |
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 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:
|
Measurement | Description | Measurement Unit | Interpretation |
---|---|---|---|
Current sessions |
Indicates the number of user sessions that are currently active across all guests |
Number |
This is a good indicator of the session load on the guests. |
New logins |
Indicates the number of new logins to the guests. |
Number |
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. |
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. |
