Configuration of VmgNicStreamTest

NICE DCV is a powerful remote visualisation protocol that enables users to securely connect to graphically intensive 3D or 2D applications hosted locally or on a remote 3D visualisation server or cluster of servers on-premises or in the cloud. It can run in your own data center or in the public cloud and delivers secure remote virtual desktops and application streaming from any location to any device, without the need for high bandwidth between the client and the remote desktop.

One of the key factors that influence user experience while appplications are remotely streamed are the latencies experienced by the user while connecting to the desktop via Nice DCV protocol and the bandwidth used when a user interacts with a virtual desktop. High latency and excessive bandwidth consumption can often slowdown access to desktops, thereby significantly delaying subsequent user operations. Hence, monitoring the latency and bandwidth usage of each user connected to virtual desktops via Nice DCV protocol is of utmost importance! This is why, the VmgNicStreamTest auto-discovers the users who are connected to virtual desktops via the Nice DCV protocol, and measures the bandwidth usage, frames processing ability, and time taken to establish each user's session. In the process, bandwidth-hungry, latent sessions can be accurately isolated.

The default parameters associated with this test are:

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

  • In the HOST text box, specify the nick name of the Cloud Desktops component for which this test is to be configured.

  • Specify the port at which the specified host listens to in the PORT text box. By default, this is NULL.

  • 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.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS button will appear in this page. Clicking on this button will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
