OS Activation / Licensing - OS Test

Operating systems across physical, virtual, and cloud-based desktops must be properly licensed and activated to ensure continued functionality, security compliance, and access to updates. License activation validates the authenticity of the OS installation and enforces compliance with enterprise or vendor licensing agreements. In large or hybrid desktop environments, administrators often face challenges such as expired or invalid licenses, activation failures, or systems nearing the end of their activation grace period. Such issues can lead to restricted functionality, user disruptions, and compliance violations if not detected in time.

This test helps administrators continuously monitor the licensing and activation status of desktops by tracking key indicators such as the current license status, remaining time to license expiry, and available Windows rearm count. By providing early visibility into activation-related issues, the test enables timely corrective actions - such as reactivation or license renewal - ensuring uninterrupted operation, compliance, and stability across all desktop environments.

Target of the test :A Physical Desktop Group

Agent deploying the test : A remote agent

Outputs of the test : One set of results is reported for the system being monitored.

Configurable parameters for the test:
Parameter	Description
Test Period	How often should the test be executed
Host	The nick name of the Physical Desktop Group component for which this test is to be configured.
Port	The port at which the specified Host listens. By default, this is NULL.
Inside View Using	To obtain the 'inside view' of performance of the desktops - i.e., to measure the internal performance of the physical 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.
Is Cloud VMs	This flag is set to Yes by default. The value of this flag cannot be changed. This implies that the cloud-based virtual desktops in environments will always be identified using the login name of the user. In other words, in cloud environments, this test will, by default, report measures for every username_on_desktopname.
Report Powered OS	This flag is relevant only for those tests that are mapped to the Physical Desktops Details layer. If this flag is set to Yes (which is the default setting), then the 'inside view' tests will report measures for even those physical desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_physicalmachinename. On the other hand, if this flag is set to No, then this test will not report measures for those physical desktops to which no users are logged in currently.
Report By User	This flag is set to Yes by default. This implies that the physical machines in environments will always be identified using the login name of the user. In other words, this test will, by default, report measures for every username_on_physicalmachinename.
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, 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
Expiry Date	Indicates the number of days beyond which the license will expire.	Days	A decreasing value signals an approaching license expiry. Administrators should renew or reactivate the license before expiry to prevent functionality restrictions.
