Default Parameters for VmgGPUAdapterTest A graphics processing unit (GPU) adapter (also known as video card, graphics card, and video adapter) is a discreet card connected to one or more physical/virtual machines. The GPU adapter contains video RAM and a GPU chip and renders real-time 2D and 3D graphics applications, images, animations and video by performing rapid mathematical calculations. To perform such calculations at higher speed, the GPU adapter should be allocated with adequate memory on the virtual machine. Inadequate memory allocation and inefficient utilization of the GPU adapter can affect the processing of intensive tasks related graphics on the virtual machines, which in turn can adversely impact the performance of the applications operating on the VMs. Therefore, it is imperative that administrators should closely observe how well the GPU adapter uses the allocated and shared memory available to it. This way, a potential memory crunch can be proactively detected. This can be achieved with the help of the VmgGPUAdapterTest. The test auto-discovers the GPU adapters connected to each virtual machine on the virtual server and for each GPU adapter, reports the statistics related to memory utilization. This test also reveals how well the GPU is utilized for performing different tasks such as video decoding, processing 3D frames, etc. These metrics help administrators to judge whether/not adequate memory is available for use by the GPU adapters and identify the GPU adapter that is running out of memory. This page depicts the default parameters that need to be configured for the VmgGPUAdapterTest. The TEST PERIOD list box helps the user to decide how often this test needs to be executed. To obtain the ‘inside view’ of performance of the cloud -hosted Windows desktops - i.e., to measure the internal performance of the Windows virtual desktops - this test uses a light -weight eGVMAgent software deployed on each of the desktops. Accordingly, Inside View Using parameter is by default set to eGVMAgent (Windows). Report Powered OS flag is relevant only for those tests that are mapped to the Inside View of Desktops layer. If this flag is set to Yes (which is the default setting), then the ‘inside view’ tests will report measures for even those Windows virtual desktops that do not have any users logged in currently. Such desktops will be identified by their name and not by the username_on_virtualdesktopname. On the other hand, if this flag is set to No, then this test will not report measures for those Windows virtual desktops to which no users are logged in currently. Report By User flag is set to Yes by default. The value of this flag cannot be changed. This implies that the virtual machines in VDI environments will always be identified using the login name of the user. In other words, in VDI environments, this test will, by default, report measures for every username_on_virtualmachinename. Since this test runs for a ‘Cloud Desktops’ component, Is Cloud VMs flag is set to Yes by default. Once the necessary values have been provided, clicking on the UPDATE button will 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.
