uftrace - Function (graph) tracer for user-space

•    C

The uftrace tool is to trace and analyze execution of a program written in C/C++. It was heavily inspired by the ftrace framework of the Linux kernel (especially function graph tracer) and supports userspace programs. It supports various kind of commands and filters to help analysis of the program execution and performance. It traces each function in the executable and shows time duration. It can also trace external library calls - but only entry and exit are supported and cannot trace internal function calls in the library call unless the library itself built with profiling enabled.

•    Javascript

Dynamic tracing for JavaScript, written in JavaScript, providing you insight into your live nodejs applications, at the process, machine, or cluster level.Similar to systems like dtrace or ktap, the goal of dynamic tracing is to enable a rich set of debugging information in live processes, often in production in order to help discover the root of an issue. These libraries have very minimal overhead when disabled, and may be enabled externally when needed.
