Default Parameters for WVDOSMemoryTest

This test reports statistics related to the usage of physical memory of the VMs.

This page depicts the default parameters that need to be configured for the WVDOSMemoryTest test.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• By default, the detailed diagnosis of the Used memory measure of this test reports the number of instances of each process running on the virtual desktop, and the aggregated memory usage (in MB and %) of every process across all its instances. For example, if users to a virtual desktop are together having 15 instances of Internet Explorer open on the desktop at around the same time, then the detailed diagnosis of the Used memory measure will compute and display the collective memory usage of all 15 instances against the Application Name, Internet Explorer. From this, you can quickly identify the exact process that is ‘collectively’ (i.e., across its instances) over-utilizing the desktop memory. In a multi-user environment such as Azure virtual desktops, administrators might want to isolate not just the process, but also similar process arguments that are guilty of abnormal memory consumption. This granular insight will take administrators closer to the root-cause of the memory bottleneck on a desktop. For instance, in the Internet Explorer example above, say 8 of the 15 IE instances are used to access the same YouTube video, and 7 instances are accessing a shopping site. In such a case, if memory usage is aggregated at the URL-level and not the process-level, then administrators can quickly identify which precise URL is draining desktop memory-the YouTube video? or the shopping site? For this, detailed diagnostics should be grouped by process arguments (eg., URLs) and not just by process/application names. To enable grouping by arguments, set the Group Processes With Arguments flag to Yes. By default, this flag is set to No.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
