Blast Sessions Test

A value of 0 indicates that the user is not currently connected to the VMware Horizon RDS server. You can use the detailed diagnosis of this measure to know which applications are currently run by a user and the resource usage of each application. Resource-hungry applications can thus be identified.

This value indicates the percentage of CPU resources that are used by applications run by this user. Excessive CPU usage by a user can impact performance for other users. Check the detailed diagnosis to view the offending processes/applications.

This value indicates the percentage of memory resources that are used up by a specific user. By comparing this value across users, an administrator can identify the Blast sessions that are engaged in memory-intensive processing on the VMware Horizon RDS server. Check the detailed diagnosis to view the offending processes/applications.

These metrics measure the collective I/O activity (which includes file, network and device I/O's) generated by all the processes being executed by a user. When viewed along with the system I/O metrics reported by the Disk Activity Test, these measures help you determine the network I/O. Comparison across users helps identify the user who is running the most I/O-intensive processes. Check the detailed diagnosis for the offending processes/applications.    

Page Faults occur in the threads executing in a process.  A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory.  If the page is on the standby list and hence already in main memory, or if the page is in use by another process with whom the page is shared, then the page fault will not cause the page to be fetched from disk. Excessive page faults could result in decreased performance. Compare values across users to figure out which user is causing most page faults.

Comparison across users reveals the user who is being a drain on the virtual memory space.

A consistent increase in the handle count over a period of time is indicative of malfunctioning of programs. Compare this value across users to see which user is using a lot of handles. Check detailed diagnosis for further information. 

The CPU usage for user’s processes measure averages out the total CPU usage of a user on the basis of the number of processors. For instance, if your VMware Horizon RDS server is using an 8-core processor and the total CPU usage of a user across all his/her sessions amounts to 80%, then the value of the CPU usage for user’s processes measure for that user will be 10 % (80/8 processors = 10). This accurately denotes the extent of CPU usage in an environment where load is uniformly balanced across multiple processors. However, in environments where load is not well-balanced, the CPU usage for user’s processes measure may not be an accurate indicator of CPU usage per user. For instance, if a single processor is used nearly 80% of the time by a user, and other 7 processors in the 8-core processor environment are idle, the CPU usage for user’s processes measure will still report CPU usage as 10%. This may cause administrators to miss out on the fact that the user is actually hogging a particular processor! In such environments therefore, its best to use the CPU time used by user’s sessions measure! By reporting the total CPU usage of a user across all his/her sessions and across all the processors the target VMware Horizon RDS server supports, this measure serves as the true indicator of the level of CPU usage by a user in dynamic environments. For instance, in the example above, the CPU time used by user’s sessions of the user will be 80% (and not 10%, as in the case of the  CPU usage for user’s processes measure). A high value or a consistent increase in the value of this measure is hence serious and demands immediate attention. In such situations, use the detailed diagnosis of the CPU usage for user’s processes measure to know what CPU-intensive activities are being performed by the user.  

Compare the value of this measure across users to know which user is consuming the maximum bandwidth.

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.

A high value is indicative of a connection bottleneck.

A poor network throughput could cause latencies in network communication.

These measures appear only if the version of the VMware Horizon is 7 and above.

Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive sound/audio files over Blast.

These measures appear only if the version of the VMware Horizon is 7 and above. When the Horizon Client and Horizon Agent are deployed with client drive redirection and the Blast is enabled, folders and files are sent across a virtual channel with encryption. This ensures that the connections between clients and the View Secure Gateway, and the connections from the View Secure Gateway to desktop machines are secure. These measures help administrators to figure out the traffic statistics during the reception/transmission of CDR data.

Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive client drive redirection data over Blast.

These measures appear only if the version of the VMware Horizon is 7 and above. Configuring the clipboard redirection on the client machine enables administrators to control users from redirecting clipboard data to and/or from the virtual desktop and the client machine during the session.

Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive clipboard redirection content during the session.

These measures appear only if the version of the VMware Horizon is 7 and above.

To redirect HTML5 multimedia content from a remote desktop to the local client system, administrators need to enable the HTML5 Multimedia Redirection feature and install the Chrome browser on the remote desktop. Enabling the HTML5 Multimedia Redirection feature also allows administrators to specify the websites that can use this feature. These measures help administrators to easily find out the bandwidth utilized during each user's session for transmitting and receiving the HTML5 multimedia content to different websites. Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive multimedia files over Blast.

This measure appears only if the version of the VMware Horizon is 7 and above. The value of this measure should be very low. A high value indicates that the image quality is potentially poor.

This measure appears only if the version of the VMware Horizon is 7 and above.

This measure appears only if the version of the VMware Horizon is 7 and above.

This measure appears only if the version of the VMware Horizon is 7 and above. This measure indicates how quickly the image frames are processed during the session. A lower value of this measure indicates that the frames are processed slowly which may lead to processing bottleneck

These measures appear only if the version of the VMware Horizon is 7 and above. Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive images over Blast.

These measures appear only if the version of the VMware Horizon is 7 and above.

With the Real-Time Audio-Video feature, webcam and audio devices that are connected locally to the client system are redirected to the remote sessions. This allows the users to run Skype, Webex, Google Hangouts, and other online conferencing applications in their remote sessions. This feature also helps administrators to redirect video and audio data with a significantly lower bandwidth than can be achieved by using USB redirection. Comparing these values across users will reveal which user is sending/receiving bandwidth-intensive real-time audio/video data during the session.

These measures appear only if the version of the VMware Horizon is 7 and above. With the serial port and scanner redirection feature, administrators can easily connect the scanner and phisical COM port devices with the virtual desktops.

These measures appear only if the version of the VMware Horizon is 7 and above. Using the values of these measures help administrators to determine the data traffic during the session.

This measure appears only if the version of the VMware Horizon is 7 and above. A value of this measure should be low. A higher value indicates unintended deviation or inconsistency that degrades the quality of audio and video communications.
