Matcher translate an elixir expression to a tracing matchspec

PidHandler is the process consumer handler of trace events It passes them to the event_callback once received

Probe manages a single probe

Helper functions to manage and validate a set of probes

Implements helper functions to find OTP process hierarchy

Orchestrates the tracing session

Supervises Tracer.Server

Module that is used by all Tool implementations

Reports duration type traces

Event generated by the CallSeq tool

Reports count type traces

Event generated by the Count tool

Reports display type tracing

Reports duration type traces

Event generated by the DurationTool

This tool generates a flame graph

Helper functions for developing tools

The ToolServer module has a process that receives the events from the pid_handler and reports the events
