User Guide :: Nsight Systems Documentation.
Important: First save your final exam settings in a. Please note that if you want to use the same. The keys for the Mac and the Windows version will in any case be different, so you have to load the final. Mac an Windows are used, or your exam settings should be tolerant to a future update of SEB to e certain extend. Session Handling Use the following parameter to control whether a browser session shall be persited on disk, e.
Ask user to confirm quitting : If not selected, then SEB quits immediately after a Quit Link is detected, without users having to confirm.
The browser session is not restarted using this feature session cookies are not cleared; a logged in user isn't logged out. Leave empty for a standard text which is localized to the SEB user interface languages. If not activated, any query parameter with the seb-Link are ignored. Setting options: Monitor processes while SEB is running: If enabled, SEB prevents non-permitted processes to display any windows including alerts, message boxes etc.
You can only deactivate this feature when using the "None for debugging only " Kiosk mode. The only way to switch off process monitoring in the other kiosk modes is to select "Ignore SEB Service" on tab "Security" see Security pane.
Permitted Processes Section Third party applications and processes which are permitted to run during an exam. Allow switching to third party applications Mac only : If this option is activated, the kiosk mode induced by SEB will be reduced one level. The process switcher Cmd-Tab will work, so it's possible to switch to other running applications. Use this option only when running SEB in a user account managed by parental controls, with only SEB and the desired applications allowed.
Also you should switch on Simple Finder and don't give users access to other accounts with administrator rights on that computer see SEB for macOS manual: Secure Environment. Allow Flash to switch to full screen mode Mac only : Playing videos with Flash in full screen mode is a security problem. That's why it is strongly recommended to use HTML5 video there full screen mode is no problem instead of Flash whenever possible.
Depending on the Flash video player and the Mac used, it can be difficult to switch back from full screen mode best is to use the Esc key , so if you don't need full screen mode, don't enable it here. When switching to third party applications is disabled, Flash fullscreen mode isn't possible at all. In general you should use this button to choose a permitted application from your drive. SEB will automatically fill in title , executable and path of the application.
You can change the title if you want which is displayed in the SEB taskbar. Path will usually be empty, as for applications which have been installed and properly registered in Windows App Paths you don't need to and should not, as it can be different on another client system specify the path. Selected Process details: Active : Indicates if this permitted process item is active can be used while testing.
Title : Application title which is displayed in the application chooser. Description : Optional, should explain what kind of process this is, because this might not be obvious only from the executable's name.
OS : Indicates on which operating system the permitted process runs currently only the option Win works. Executable : File name of the executable, which should not contain any parts of a file system path , only the filename of the exe file like calc. Original Name : Original file name of the executable. Some files don't have this metadata information. If it is available, SEB will prioritize this string over the Executable file name string.
Window Handling Process : Process executable which is actually handling the main window, this is necessary to indicate for Java and some other applications for example OpenOffice, Eclipse, Adobe Acrobat. Path : Optional filesystem path formatted system specific to the process executable's directory excluding the filename, see field executable.
If the path is not given or relative, then SEB searches the system provided paths for applications. For applications which have been installed and properly registered in Windows App Paths you don't need to specify the path. If the executable for an application is placed in a subdirectory of the path registered in Windows App Paths, then you usually can indicate just the relative path.
SEB also is able to expand environment variables in path of permitted processes. Arguments to append to the executable of the application when starting it. You can select if an argument is active or not for testing. Icon in taskbar : Disabling this option is mainly useful for background processes not requiring user interaction which you want to autostart when SEB is run.
Autostart : Start the process automatically together with SEB. Identifier: String of the process identifier in reverse domain notation Mac or the string or substring of the main window title of a process which doesn't have a MainWindow handle Win , this is usually the case with Java applications use for example "OpenOffice" for OpenOffice Calc.
Allow running in background : Permitted processes with this option set are allowed to already be running when starting SEB. Processes with the option "Allow running in background" don't have an icon in the SEB taskbar. They can nevertheless have the option "Autostart" set, in this case SEB attempts to start the permitted process regardless if it was already running or not and the option "Icon in taskbar" is considered in this case. Allow user to select location of application : The user is presented a file dialog window allowing to locate the third party application's executable if it cannot be found at the path specified and paths provided by the system instead of just displaying an error message.
Only applications matching the executable string specified are accepted. Disabling this setting does not mean that processes are not killed: Depending on the platform's capabilities, SEB first tries to terminate prohibited processes and applications nicely or asking the user to do it themselves, if this doesn't work then it terminates them anyways as long as monitor processes is enabled.
But enabling Force quit will speed up this process. This flag should not be set for macOS applications which allow to be terminated nicely they are anyways automatically terminated, without asking the user. Prohibited Processes Section List of processes which are prohibited to run during an exam. Selected Process details: Active : Indicates if this prohibited process item is active.
Executable : Process name, usually the filename of the executable. Disabling this setting does not mean that processes are not killed: Depending on the platform's capabilities, SEB first tries to terminate prohibited processes nicely or asking the user to do it themselves, if this doesn't work then it terminates them anyways as long as monitor processes is enabled. Filter also embedded content : If selected, also all embedded resources will be filtered using the filter set.
Note that there can be hundreds of resources such as images and other media per page, so filtering all content may slow down page loading. Rules Active : Indicates if the rule is active. Regex : Indicates if the rule is a regular expression. Action to process if the corresponding expression matches. Possible actions: block If the URL matches the expression, then it is rejected and processing of the remaining rules is stopped. If the URL filter reaches the last rule means there was no matching block or allow expression found , then the URL is discarded.
The host field is required besides when filtering against a protocol like about:blank or data: , and is either a partial or full hostname or an IP address. The URL filter doesn't resolve hostnames itself, so if you allow everything and only block 'hostname.
You should therefore mainly use whitelisting to allow accessing only specific sites during an exam. An optional '. An optional port can come after the host and always has to start with the character ':'. It must be a valid port value from 1 to URL parameters like a query string can be indicated and always have to start with the character '?
Filtering against a fragment usually doesn't make sense, as the content can be reached by scrolling the loaded page. Allowing specific fragments could force people to use a link to a particular anchor on a page other links would not work. Examples for filter expressions: 'example. The order of filter rules is not relevant. Here you can choose SSL server certificates which are stored in the Windows Certificate Store if you have a certificate file, usually in the. The certificates added to this table will be embedded into a.
Users then won't be presented a warning then when connecting to https servers with those self-signed certificates and you don't need to distribute SSL certificates manually to the exam client computers. Debug certificate: Debug certificates allow changing the DNS name you can overwrite the certificate name in the certificate list , so a server with a wrong domain name is accepted if its domain is entered in the certificate name field.
Expired certificates are also accepted. Choose identity to embed into configuration If you have a. When importing the. The identities added to this table will be embedded into the. Use this feature for creating a. When opening this. Please note that during this process the private keys imported into the Windows Certificate Store of the exam clients will be flagged as non-exportable for increased security.
The problem occurs when your server certificate is signed by an intermediate certificate of any trusted certification authority. In that case the whole issuer chain must be provided to the browser for validation. You might have to ask your server administrator to change their settings to solve the problem.
For further information please consult the documentation of your web server: Apache 2. There is a discussion about this problem in our forum too. Proxies Section In this pane you can configure proxy settings for the exam client computers which override the system's proxy settings on the clients.
Adding new reports is as simple as writing a script that can read the SQLite file and generate the required CSV output. See the shipped scripts as an example. Both reports and formatters may take arguments to tweak their processing. For details on shipped scripts and formatters, see Report Scripts topic. Reports are processed using a three-tuple that consists of 1 the requested report and any arguments , 2 the presentation format and any arguments , and 3 the output filename, console, or external process.
The first report specified uses the first format specified, and is presented via the first output specified. The second report uses the second format for the second output, and so forth.
After choosing the stats command switch, the following options are available. The nsys analyze command generates and outputs to the terminal a report using expert system rules on existing results.
If no SQLite export file exists, one will be created. After choosing the analyze command switch, the following options are available. The nsys status command returns the current state of the CLI. After choosing the status command switch, the following options are available.
After choosing the sessions command switch, the following subcommands are available. After choosing the sessions list command switch, the following options are available. Effect: Launch the application using the given arguments.
Start collecting immediately and end collection when the application stops. Collect CPU sampling information and thread scheduling information.
With Nsight Systems Workstation Edition this will trace the process tree. Generate the report. Start collecting immediately and end collection after 20 seconds or when the application ends.
Do not collect CPU sampling information or thread scheduling information. Profile any child processes. Launch the application using the given arguments. Start collecting after 20 seconds and end collection at application exit.
Collect CPU sampling and thread schedule information. Note that ftrace event collection requires running as root. To get a list of ftrace events available from the kernel, run the following:. Effect: Launch application. Effect: Configure custom ETW collectors using the contents of file. Collect data for 20 seconds. Effect: Create interactive CLI process and set it up to begin collecting as soon as an application is launched. Stop only when explicitly requested. Run application, begin collection manually, run until process ends.
Effect: Create interactive CLI and launch an application set up for default analysis. Send application output to the terminal. No data is collected until you manually start collection at area of interest. Profile until the application ends. If you launch an application and that application and any descendants exit before start is called Nsight Systems will create a fully formed.
Launch application for default analysis, sending application output to the terminal. Stop collection at next call to cudaProfilerStop, when the user calls nsys stop , or when the root process terminates. This will be corrected in a future version. Effect: Create interactive CLI process and set it up to begin collecting as soon as an NVTX range with given message in given domain capture range is opened.
Stop collection when all capture ranges are closed, when the user calls nsys stop , or when the root process terminates. Message Domain: All ranges with given message in given domain are capture ranges. For example:. This would make the profiling start when the first range with message "profiler" is opened in domain "service". This would make the profiling start when the first range with message "profiler" is opened in any domain. Message: All ranges with given message in default domain are capture ranges.
This would make the profiling start when the first range with message "profiler" is opened in the default domain. By default only messages, provided by NVTX registered strings are considered to avoid additional overhead. No data is collected until the start command is executed.
Collect data from start until stop requested, generate report. Collect data from second start until the second stop request, generate report.
Shutdown the interactive CLI and send sigkill to the target application's process group. Calling nsys cancel after nsys start will cancel the collection without generating a report. Effect: Export an SQLite file named report1. Print the default reports in column format to the console. Note: The following two command sequences should present very similar information:.
Print the report generated by the gputrace script to the console in column format. Generate multiple reports, in multiple formats, output multiple places. Generate three reports. The other two reports, gpukernsum and cudaapisum , will be output to the console as columns of data. Although three reports were given, only two formats and outputs are given. To reconcile this, both the list of formats and outputs is expanded to match the list of reports by repeating the last element.
Effect: Open test. Generate table data and feed that into the command grep -E - Name cudaFree. The grep command will filter out everything but the header, formatting, and the cudaFree data, and display the results to the console. Note: When the output name starts with , it is defined as a command. The command is run, and the output of the report is piped to the command's stdin standard-input. The command's stdout and stderr remain attached to the console, so any output will be displayed directly to the console.
Be aware there are some limitations in how the command string is parsed. The command cannot be piped to another command, nor redirected to a file using shell syntax.
The command and command arguments are split on whitespace, and no quotes within the command syntax are supported. For commands that require complex command line syntax, it is suggested that the command be put into a shell script file, and the script designated as the output command. The nsys stats command can be used post analysis to generate specific or personalized reports. For a default fixed set of summary statistics to be automatically generated, you can use the --stats option with the nsys profile or nsys start command to generate a fixed set of useful summary statistics.
Recipes for these statistics as well as documentation on how to create your own metrics will be available in a future version of the tool. The CLI generates a. It needs to be processed, either by importing it into the GUI or by using the standalone QdstrmImporter to generate an optimized. Use this. This version of Nsight Systems will attempt to automatically convert the. The ability to turn off auto-conversion will be added in a later version. The host GUI is backward compatible only with.
Copy the. The import of really large, multi-gigabyte,. This will be fixed in a later version. Simply choose the. QdstrmImporter is available for all host platforms. See options below. If you require more control over the list of traced APIs or if you are using a different MPI implementation, see github nvtx pmpi wrappers. Each instance will create a separate report file. You cannot use multiple instances of the interactive CLI concurrently, or use the interactive CLI concurrently with nsys profile in this version.
Nsight Systems can be used to profile applications launched with mpirun command. To profile everything putting the data from each rank into a separate file:. Currently you will need a dummy argument to the process, so that Nsight Systems can decide which process to profile.
This means that your process must accept dummy arguments to take advantage of this workaround. Nsight Systems provides a simple interface to profile on localhost or manage multiple connections to Linux or Windows based devices via SSH. The network connections manager can be launched through the device selection dropdown:. The dialog has simple controls that allow adding, removing, and modifying connections:. Security notice : SSH is only used to establish the initial connection to a target device, perform checks, and upload necessary files.
The actual profiling commands and data are transferred through a raw, unencrypted socket. Nsight Systems should not be used in a network setup where attacker-in-the-middle attack is possible, or where untrusted parties may have network access to the target device.
While connecting to the target device, you will be prompted to input the user's password. Please note that if you choose to remember the password, it will be stored in plain text in the configuration file on the host. Stored passwords are bound to the public key fingerprint of the remote device. The No authentication option is useful for devices configured for passwordless login using root username. Then set empty password using passwd and restart the SSH service with service ssh restart.
Open ports : The Nsight Systems daemon requires port 22 and port to be open for listening. You can confirm that these ports are open with the following command:. To open a port use the following command, skip --permanent option to open only for this session:. Likewise, if you are running on a cloud system, you must open port 22 and port for ingress. Kernel Version Number - To check for the version number of the kernel support of Nsight Systems on a target device, run the following command on the remote device:.
Additionally, presence of Netcat command nc is required on the target device. For example, on Ubuntu this package can be installed using the following command:. System-wide profiling is available on x86 for Linux targets only when run with root privileges. Tracing of context switching on the GPU is enabled with driver r Trace all processes — On compatible devices with kernel module support version 1.
Scheduler events from all tasks will be recorded. Enable specific counters when interested in correlating cache misses to functions in your application.
Three different backtrace collections options are available when sampling CPU instruction pointers. LBR backtraces generate minimal overhead but the backtraces have limited depth. Finally, backtraces can be generated using frame pointers.
Frame pointer backtraces incur medium overhead and have good depth but only resolve frames in the portions of the application and its libraries including 3rd party libraries that were compiled with frame pointers enabled. Normally, frame pointers are disabled by default during compilation. Choose modes The Include child processes switch controls whether API tracing is only for the launched process, or for all existing and new child processes of the launched process.
If you are running your application through a script, for example a bash script, you need to set this checkbox. The Include child processes switch does not control sampling in this version of Nsight Systems. The full process tree will be sampled regardless of this setting.
This will be fixed in a future version of the product. Nsight Systems can sample one process tree. When sampling the CPU on a workstation target, Nsight Systems traces thread context switches and infers thread state as either Running or Blocked.
Note that Blocked in the timeline indicates the thread may be Blocked Interruptible or Blocked Uninterruptible.
Blocked Uninterruptible often occurs when a thread has transitioned into the kernel and cannot be interrupted by a signal. Currently Nsight Systems can only sample one process. Sampling here means that the profilee will be stopped periodically, and backtraces of active threads will be recorded.
Most applications use stripped libraries. In this case, many symbols may stay unresolved. If unstripped libraries exist, paths to them can be specified using the Symbol locations Symbol resolution happens on host, and therefore does not affect performance of profiling on the target. Additionally, debug versions of ELF files may be picked up from the target system. Nsight Systems Workstation Edition can use hotkeys to control profiling.
This is useful when tracing games and graphic applications that use fullscreen display. In these scenarios switching to Nsight Systems ' UI would unnecessarily introduce the window manager's footprint into the trace. To enable the use of Hotkey check the Hotkey checkbox in the project settings page:. The purpose of the configuration here is to define which process the profiler will attach to for sampling and tracing.
Additionally, the profiler can launch a process prior to attaching to it, ensuring that all environment variables are set correctly to successfully collect trace information. In Attach only mode, the process is selected by its name and command line arguments, as visible using the ps tool. In Attach or launch mode, the process is to first search as if in the Attach only mode, but if it is not found, the process is launched using the same path and command line arguments.
Note that in some cases, the capabilities of Nsight Systems are not sufficient to correctly launch the application; for example, if certain environment variables have to be corrected. In this case, the application has to be started manually and Nsight Systems should be used in Attach only mode. The Edit arguments This is convenient when arguments contain spaces or quotes.
To properly populate the Search criteria field based on a currently running process on the target system, use the Select a process button on the right, which has ellipsis as the caption. The list of processes is automatically refreshed upon opening. Attach by PID mode should be used to connect to a specific process.
To choose one of the currently running processes on the target system, use the Select a process button on the right. Profiling on Windows devices is similar to the profiling on Linux devices. Please refer to the Profiling Linux Targets from the GUI section for the detailed documentation and connection information.
The major differences on the platforms are listed below:. To perform remote profiling to a target Windows based machines, install and configure an OpenSSH Server on the target machine.
The default value is which corresponds to 0x7B, or the F12 key. Note that you must convert the hexadecimal values detailed in this page to their decimal counterpart before using them in the file.
Sampling here means interrupting each processor periodically. On Windows, Nsight Systems can collect thread activity of one process tree. Collecting thread activity means that each thread context switch event is logged and optionally a backtrace is collected at the point that the thread is scheduled back for execution.
Thread states are displayed on the timeline. If it was collected, the thread backtrace is displayed when hovering over a region where the thread execution is blocked. Press the Symbol locations Information about Microsoft's public symbol server, which enables getting Windows operating system related debug symbols can be found here.
Profiling on QNX devices is similar to the profiling on Linux devices. Backtrace sampling is not supported. Instead backtraces are collected for long OS runtime libraries calls. Filesystem on QNX device might be mounted read-only. In that case Nsight Systems is not able to install target-side binaries, required to run the profiling session. Please make sure that target filesystem is writable before connecting to QNX target. For example, make sure the following command works:. Nsight Systems has the ability to export SQLite database files from the.
From the CLI, use nsys export. Note: The. The SQLite schema can and will change in the future. The schema for a concrete database can be obtained with the sqlite3 tool built-in command. The sqlite3 tool can be located in the Target or Host directory of your Nsight Systems installation. Note: Currently tables are created lazily, and therefore not every table described in the documentation will be present in a particular database.
This will change in a future version of the product. Currently, a table is created for each data type in the exported database. Since usage patterns for exported data may vary greatly and no default use cases have been established, no indexes or extra constraints are created. Instead, refer to the SQLite Examples section for a list of common recipes.
This may change in a future version of the product. The first value, or major value, indicates the overall format of the database, and is only changed if there is a major re-write or re-factor of the entire database format. It is assumed that if the major version changes, all scripts or queries will break. The middle, or minor, version is changed anytime there is a more localized, but potentially breaking change, such as renaming an existing column, or changing the type of an existing column.
The last, or micro version is changed any time there are additions, such as a new table or column, that should not introduce any breaking change when used with well-written, best-practices queries. The difference between text and textId columns is that if an NVTX event message was passed via call to nvtxDomainRegisterString function, then the message will be available through textId field, otherwise the text field will contain the message if it was provided.
OS runtime libraries can be traced to gather information about low-level userspace APIs. This traces the system call wrappers and thread synchronization interfaces exposed by the C runtime and POSIX Threads pthread libraries. This does not perform a complete runtime library API trace, but instead focuses on the functions that can take a long time to execute, or could potentially cause your thread be unscheduled from the CPU while waiting for an event to complete.
OSRT events may have callchains attached to them, depending on selected profiling settings. Default column width is determined by the data in the first row of results. Nsight Systems stores identifiers where events originated in serialized form.
Please note, that Nsight Systems applies additional logic during sampling events processing to work around lost events. Thread running time may be calculated using scheduling data, when PMU counter data was not collected. These examples demonstrate how to calculate Flat and BottomUp for top level only views statistics.
The example demonstrates how to calculate DX12 CPU frames durartion and construct a histogram out of it. The example demonstrates how to query SLI Peer-to-Peer events with resource size greater than value and within a time range sorted by resource size descending. The Arrow type exported file uses the IPC stream format to store the data in a file.
The tables can be read by opening the file as an arrow stream. For more information on the interfaces that can be used to read an IPC stream file, please refer to the Apache Arrow documentation [ 1 , 2 ]. The name of each table is included in the schema metadata.
Thus, while reading each table, the user can extract the table title from the metadata. First, all collected events are processed. Then strings are serialized, followed by stdout, stderr streams if any, followed by thread names. For easier grepping of JSON output, the --separate-strings switch may be used to force manual splitting of strings, streams and thread names data.
Example line split: nsys export --export-json --separate-strings sample. Compare with: nsys export --export-json sample. Note, that only last few lines are shown here for clarity and that carriage returns and indents were added to avoid wrapping documentation. The Nsight Systems development team created and maintains a set of report scripts for some of the commonly requested reports.
These scripts will be updated to adapt to any changes in SQLite schema or internal data structures. The following standard reports are available:. This report combines data from the cudaapisum , gpukernsum , and gpumemsizesum reports.
It is very similar to profile section of nvprof --dependency-analysis. This report provides a summary of CUDA kernels and their execution times. This report provides a summary of GPU memory operations and the amount of memory they utilize. This report provides a summary of GPU memory operations and their execution times. This report provides a summary of CUDA kernels and memory operations, and their execution times. This report combines data from the gpukernsum and gpumemtimesum reports. This report is very similar to output of the command nvprof --print-gpu-summary.
This report displays a trace of CUDA kernels and memory operations. Items are sorted by start time. This report provides a summary of OpenMP events and their execution times. This report provides a summary of operating system functions and their execution times. This report provides a summary of Vulkan debug markers on the CPU, and their execution times.
The column formatter presents data in vertical text columns. It is primarily designed to be a human-readable format for displaying data on a console display. Text data will be left-justified, while numeric data will be right-justified.
If the data overflows the available column width, it will be marked with a "…" character, to indicate the data values were clipped. Clipping always occurs on the right-hand side, even for numeric data. Numbers will be reformatted to make easier to visually scan and understand.
This includes adding thousands-separators. This process requires that the string representation of the number is converted into its native representation integer or floating point and then converted back into a string representation to print.
This conversion process attempts to preserve elements of number presentation, such as the number of decimal places, or the use of scientific notation, but the conversion is not always perfect the number should always be the same, but the presentation may not be. To disable the reformatting process, use the argument nofmt. If no explicit width is given, the columns auto-adjust their width based off the header size and the first lines of data.
This auto-adjustment is limited to a maximum width of characters. To allow larger auto-width columns, pass the initial argument nolimit. If the first lines do not calculate the correct column width, it is suggested that explicit column widths be provided.
The table formatter presents data in vertical text columns inside text boxes. Other than the lines between columns, it is identical to the column formatter.
The csv formatter outputs data as comma-separated values. If you configure an explicit proxy server in the VDA and route connections to localhost through a proxy, redirection fails. If not, optimization fails. If the branch office is configured to access the internet through a proxy, these versions support proxy servers:.
If DNS requests are unsuccessful, P2P calls with outside users and conference calls media establishment fails. This support means that the endpoint must be able to perform DNS resolutions. Consider a scenario where there is no direct path between the two peers or between a peer and a conference server and you are joining a multi-party call or meeting. The HdxRtcEngine. These ranges include both Transport Relays and media processors, front-ended by an Azure Load Balancer.
Call quality depends on the underlying network protocol. Meetings fail. Use this architecture diagram as a visual reference for the call flow sequence.
The corresponding steps are indicated in the diagram. Citrix media engine and Teams. With Direct Routing, you connect your own supported session border controller to the Microsoft Phone System directly without any additional on-premises software. Call queues, transfer, forward, hold, mute, and resume a call are supported.
Starting with version , Citrix Workspace app supports dynamic emergency calling. The notification is provided based on the current location of the Citrix Workspace app that runs on the endpoint, instead of the Microsoft Teams client that runs on the VDA. To enable dynamic emergency calling, the administrator must use the Microsoft Teams Admin Center and configure the following to create a network or emergency location map:. When users start an optimized call using the Microsoft Teams client for the first time, they might notice a warning with the Windows firewall settings.
The warning asks for users to allow communication for HdxTeams. You can apply more restrictive rules if you want. You can deploy Microsoft Teams and Skype for Business side by side as two separate solutions with overlapping capabilities.
For more information, see Understand Microsoft Teams and Skype for Business coexistence and interoperability. Examples include island modes and Skype for Business with Microsoft Teams collaboration.
Also, Skype for Business with Microsoft Teams collaboration and meetings. Peripheral access can be granted only to a single application at the time. For example, webcam access by the RealTime Media Engine during a call locks the imaging device during a call. When the device is released, it becomes available for Microsoft Teams. Optimal audio and video quality require a network connection to the Microsoft cloud that has low latency, low jitter, and low packet loss.
Backhauling of Microsoft Teams audio-video RTP traffic from Citrix Workspace app users at branch office locations to a data center before going to the internet can add excessive latency. It might also cause congestion on WAN links. This use is to identify, categorize, and steer Microsoft Teams traffic.
Business broadband internet connections in many areas suffer from intermittent packet loss, periods of excessive jitter, and outages. Microsoft Teams supports Gallery , Large gallery , and Together mode layouts. Microsoft Teams displays a 2x2 grid with video streams of four participants known as Gallery. In this case, Microsoft Teams sends four video streams to the client device for decoding. When more than four participants share video, only the last four most active speakers appear on the screen.
Microsoft Teams also provides the large gallery view with a grid up to 7x7. As a result, the Microsoft Teams conference server composites a single video feed and sends it to the client device for decoding, resulting in lower CPU consumption. Lastly, Microsoft Teams supports Together mode , which is part of the new meeting experience. Using AI segmentation technology to digitally place participants in a shared background, Microsoft Teams puts all participants in the same auditorium.
The user can control these modes during a conference call by selecting Gallery , Large gallery , or Together mode layouts in the ellipses menu. Microsoft Teams relies on video-based screen sharing VBSS , effectively encoding the desktop being shared with video codecs like H and creating a high-definition stream. With HDX optimization, incoming screen sharing is treated as a video stream. Instead, the screen sharing video feed shows. The peer must then manually resume the camera sharing.
In that case, other peers can still see your webcam and content and navigate back and forth to review other slides. In this scenario, the slides are rendered on the VDA. Outgoing screen sharing is also optimized and offloaded to Citrix Workspace app. Set specific permission in Citrix Workspace app for Mac to enable screen sharing.
For more information, see System Requirements. Citrix Workspace app minimum version is required. Starting with Citrix Workspace app for Windows To share a specific app:.
Compatibility with app protection The screen sharing of a specific app is compatible with the app protection feature in HDX optimized Microsoft Teams. You can only select the Window option to share any open app.
You can use multiple meetings or chat windows for Microsoft Teams in Windows. This feature is available only after the roll-out of an update from Microsoft Teams. For information on ETA, see Microsoft page. When the update is rolled-out by Microsoft, you can check CTX for the documentation update and the announcement.
This feature will be supported with Citrix Workspace app for Windows This feature is supported in the following versions of Citrix Workspace app there is no dependency on the VDA version or Operative System, single session or multisession :. You can request control during a Microsoft Teams call when a participant is sharing the screen. Once you have control, you can make selections, edits, or other keyboard and mouse activities to the shared screen.
To take control when a screen is being shared, click Request control button in the Microsoft Teams UI. While you have control, you can make selections, edits, and other modifications to the shared screen. For these actions, you can use both keyboard and mouse.
Give and Request control are not available if the user is sharing a single app also known as App sharing. The full desktop or monitor must be shared. When optimization for Microsoft Teams is active, the Citrix Workspace app accesses the peripherals headsets, microphones, cameras, speakers, and so forth. Microsoft Teams does not access the devices directly. Instead, it relies on the Workspace app WebRTC media engine for acquiring, capturing, and processing the media.
Microsoft Teams lists the devices for the user to select. After the peripheral is selected, Microsoft Teams caches the information of the peripherals. As a result, the peripherals are automatically selected when you reconnect to a session from the same endpoint.

Google's upcoming change replaces this generic button with a Google Meet button. Third-party apps are relegated to a dropdown menu, which you can bring up by clicking an arrow. Design choices like this are never accidental.
