Sequality Embedded System Monitor

Monitor and Configure your embedded Linux Device with a responsive Qt and HTML5 App

The Sequality Embedded System Monitor provides a convenient user interface to visualize all system resources of an embedded Linux board. You can monitor all important performance-critical values in real time and have configuration access to important hardware resources like WIFI, ethernet and CAN. The software can serve as a basis implementation for your customized product. With this component, a user friendly responsive system configuration can be integrated in your own Embedded Linux product.


  • System-Information: Visualization of CPU, memory, CAN bus, network and disk-space of your embedded device. Nice and tidy, all in one place!
  • QR-code-connect: Connect to your embedded device directly with WIFI – just scan the QR-Code generated and get access to the web app.
  • Network management: Remotely configure your network interfaces on your embedded Linux device – static or dynamic IP, wireless network scans, wireless network password – with a user friendly graphical interface in your Qt app or in your browser.
  • CAN-Bus: See which CAN messages come in at real time and do CAN bus message analysis – see cycle times and complete can log!
  • Web-Console for root-access to your embedded device within the browser-app.
  • Remote-View: You are running a GUI application on your device and want to monitor the contents of your screen? No problem – get a remote view of the display within the browser app.
  • Dual-Screen HDMI: With selected embedded Linux Boards that offer two HDMI ports, you can start the Sequality Embedded System Monitor on two screens. For instance, you can show system information on one screen and a live digital camera stream on the second screen.
  • Digital Camera View editor: Show a low-latency video stream of the digital camera interface on your embedded Linux board or with a connected IP ethernet camera! By using an optimized Gstreamer pipeline with Qt Multimedia, the hardware video decoder of the i.Mx8 is used in an efficient way. Once rendered on the Qt screnegraph, you can rotate, mirror or crop the video stream or place cutom overlay graphics on the stream.
  • Demonstrate all native features of your embedded Linux Device with a native Qt app. Real-time propagation to all HTML5 or Qt-native clients!

More Details

  • Dual-Screen functionality is implemented as discussed in our blog-post here: How to implement a dual display setup with embedded Linux and Qt
  • This application uses the sequality HTML5 & Qt architecture discussed in our HTML5 vs Qt videos and whitepaper with a C++ Qt backend, a Qt Quick native user interface and, for configuration purposes, an angular HTML5 web application.
  • The HTML5 application using Angular is served by a web server running on the embedded Linux device. Optionally we can use a QtWebView to also display the HTML5 application full-screen on the embedded device (see screenshots above). See here for further video comparisions of different approaches.
  • Network-Configuration features were implemented using linux network-manager and NetworkManagerQt. This provides a good interface for WIFI connection handling, security handling and authentication (e.g. EAP).
