| Tracing |
| ####### |
| |
| Overview |
| ******** |
| |
| The tracing feature provides hooks that permits you to collect data from |
| your application and allows enabled backends to visualize the inner-working of |
| the kernel and various subsystems. |
| |
| Applications and supported tools can define empty macros declared in |
| :file:`include/tracing.h` that are called across the kernel in key spots. |

| SEGGER SystemView Support |
| ************************* |
| |
| Zephyr provides built-in support for `SEGGER SystemView`_ that can be enabled in |
| any application for platforms that have the required hardware support. |
| |
| To enable tracing support with `SEGGER SystemView`_ add the configuration option |
| :option:`CONFIG_SEGGER_SYSTEMVIEW` to your project configuration file and set |
| it to *y*. For example, this can be added to the |
| :ref:`dining-philosophers-sample` to visualize fast switching between threads. |
