This is about the LTTng-based framework used to detect memory allocation and system blocking calls.

A decent amount of code already resides in:

Acceptance

  1. extract apex_tracing_check package to external public repo
  2. provide the documentation

Just a follow-up regarding @ralph-lange's question (during the RTWG meeting today) about integrating this into ROS 2.

The tracepoints for this framework are in malloc/open/write/read/select/poll/etc. functions inside an LD_PRELOADed shared lib, so they are not like the tracepoints that ros2_tracing provides for ROS 2 directly.

However, while it wouldn't be as easy to use as ros2_tracing, what we can do here is integrate it with ament to make it easy to setup/use. It's already somewhat integrated but it could be polished.
