Blast Session - OS Test

The BLAST Session protocol allows files on a remote computer to be manipulated - i.e., to be deleted, renamed, or printed on the remote. Owing to the improved remote file management capabilities that Blast offers, many hypervisors like VMware support the Blast protocol too for user communication with Omnissa Horizon desktops. Because of this, there is a need to know which users have connected to Omnissa Horizon desktops via Blast and how the experience of each user is. This is why, the Blast Session - OS test auto-discovers the users who are connected to Omnissa Horizon desktops via the Blast protocol, and measures the bandwidth usage, frames processing ability, throughput, and time taken to establish each user's session. In the process, bandwidth-hungry, latent sessions can be accurately isolated.

Target of the test : A Omnissa Horizon desktop on the cloud

Agent deploying the test : A remote agent

Outputs of the test : One set of results for every user who is connected to a Omnissa Horizon desktop via the Blast protocol

Configurable parameters for the test
Parameter	Description
Test Period	How often should the test be executed.
Host	The nick name of the Omnissa Horizon Desktops component for which this test is to be configured.
Port	Refers to the port at which the specified host listens to. By default, this is NULL.
Inside View Using	To obtain the 'inside view' of performance of the cloud-hosted Omnissa Horizon desktops - i.e., to measure the internal performance of the Omnissa Horizon 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 (Omnissa Horizon).
Report Powered OS	This 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 Omnissa Horizon 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 Omnissa Horizon desktops to which no users are logged in currently.
Report By User	This 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.
Is Cloud VMs	Since this test runs for 'Omnissa Horizon Desktops' component which is a cloud-hosted desktop group, this flag is set to Yes by default.
DD Frequency	Refers to the frequency with which detailed diagnosis measures are to be generated for this test. For instance, if you set to 1:1, it means that detailed measures will be generated every time this test runs, and also every time the test detects a problem.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG suite 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
Round trip time	Indicates the round trip latency between the Omnissa Horizon desktop and this user terminal.	Seconds	Comparing the value of this measure across users will enable administrators to quickly and accurately identify users who are experiencing higher latency when connecting to a Omnissa Horizon desktop. via Blast.
Bandwidth	Indicates the bandwidth usage of all sessions of this user.	Kbps	Compare the value of this measure across users to know which user is consuming the maximum bandwidth.
Frame rate	Indicates the rate at which frames are processed during this user's sessions.	Frames/Sec	FPS is how fast your graphics card can output individual frames each second. It is the most time-tested and ideal measure of performance of a GPU. Higher the value of this measure, healthier is the GPU.
Throughput	Indicates the network throughput of this user's sessions.	Kbps	A poor network throughput could cause latencies in network communication.
