Tracing with Tracy

Requirements

One of the tracing backends Monado has is Tracy. Note, that the backend is fully integrated so you only need to make sure that the correct CMake flags are set, XRT_HAVE_TRACY and XRT_FEATURE_TRACING. Building the Tracy profiler is also required, but the order doesn't matter.

  • Get the Tracy profiler.
    • Linux: build it, needs glfw3, freetype2 & capstone dev packages.
    • Windows: download release binaries from page, or build it.
  • Build Monado with XRT_FEATURE_TRACING & XRT_HAVE_TRACY being ON.

Running

Start the Tracy profiler, either try to connect directly to the host you want to run Monado on, or wait for it to show up in the first initial UI. Then run Monado like you normally would, for example as follows.

monado-serivce

Notes

Unlike @ref tracing-perfetto Tracy supports Windows, it also supports live viewing of the data stream. But Tracy can only trace one application at a time, whereas Perfetto can do multiple processes at the same time and whole system tracing, giving a higher level overview of the whole system.
