seq_trace

• http://erlang.org/doc/man/seq_trace.html

This app serves as a small demo of putting together:

• Plug
• telemetry
• seq_trace

A test adds a few telemetry handlers, the first of which will start a seq_trace inside our request process:

• test/seq_trace_intro_test.exs

The plug spawns a few nested Tasks and is able to fetch the cross-process trace context:

• lib/seq_trace_intro/plug.ex
