Visualizer <Tracing Behavior> [Vzet]
Various applications consisting of multiple processes are running on Linux system. Vzet is an innovative product to visualize such processes for you.


"What to see" and "How to see"
         on Linux/Android --- As you choose!

  • With Vzet, you can see:
      Not only entire operation of the CPU but a specific process,
      Running transition and CPU utilization of each process,
      Specific process you choose, and kernel events as well!
  • And more features:
      Working with every version of ftrace and event trace,
      Superimpose display on logcat (Android) data, and
      Remote tracing is available (SSH,ADB-TCPIP,ADB-USB)

  • Vzet is available for multi-core(SMP/AMP), multi-process, multi-thread Display over 100,000 lines of trace data instantaneously, Vzet guides and navigates you crossing the "sea of processes"!

  • For System Development
  • Confirmation of application running in the whole system
    Confirmation of load distribution of multi-core
  • For Application Development
  • Confirmation of application related to you / your team
  • Flexible Data-Representation
  • For specific CPU, and for each process
    Events in Linux kernel can be superimposed
    Colors to display and process names are customizable
  • Events time and CPU load/time can be exported to files in csv format
    For specified time region, data (Events or PID switch) can be counted
    ftrace log file can be viewed in text form
  • Visualize Android
  • Transfer logcat data to the host via adb
  • Superimpose display on application execution state
  • Support linkage of Android application debugging info and the kernel
  • Visualize Linux data under /proc
  • Collect and show various Linux system information including process (thread) info, memory info and more
  • Your own shell script or binary program are usable with Vzet for data collection, and such data is formatted either by Vzet-standard or your own process then visualized
  • Give descriptions to major variables
  • Display concurrently with the visualization of ftrace

    The traditional tool has difficulties to deal with the tool requirements for both system development and application development, since they are close but not the same conditions. However, Vzet is equally utilizable for system development and application development.

  • About ftrace
    Vzet is a software to visualize ftrace log data. ftrace has been implemented as a standard from kernel version 2.6.27 and 2.6.25-rt. It works as a static tracer, which directly calls tracing in kernel codes and faster than dynamic tracers. Plug-in is available for feature enhancement, so it will be expanded more in the near future.
