TMT: Thread Monitoring Tool

TMT is a simple tool that leverages eBPF to trace and analize the amount of threads that a targeted application uses during its execution.

Usage

To monitor an application with TMT, simply run

   sudo ./tmt.py my_application

By default, TMT will produce two different plots: one in which each changes in thread count is coherent with timestamps, and another in which the distance on time is uniform.

It is also possible to print to stdout intermediate information:

• --print-raw prints the raw events captured by the application
• --print-tree prints a tree of the processes that have been created
• --print-intervals prints on screen a summary of the thread alive at different timestamps
