LTTng
LTTng (Linux Trace Toolkit Next Generation) is a system software package for correlated tracing of the Linux kernel, applications and libraries. LTTng consists of kernel modules (for Linux kernel tracing) and dynamically linked libraries (for application and library tracing). It is controlled by a session daemon, which receives commands from a command line interface, lttng. The babeltrace project allows translating traces into a human-readable log, and provides a trace reading library, libbabeltrace.
