Monitoring tools

SystemTap^[1] provides stap target command line tool.

SystemTap provides free software (GPL) infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem.

SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel plus user-space applications. We are publishing samples, as well as enlarging the internal "tapset" script library to aid reuse and abstraction.

Among other tracing/probing tools, SystemTap is the tool of choice for complex tasks that may require live analysis, programmable on-line response, and whole-system symbolic access. SystemTap can also handle simple tracing jobs.

3. Installing the trace and debug tool on your target board[edit source]

3.1. Using STM32MPU Embedded Software distribution[edit source]

stap from systemtap is installed by default and ready to be used with all STM32MPU Embedded Software Packages.
