header in Plug
applications by exposing Telemetry events as metrics in HTTP headers. This
allows developers to use their's browser DevTools to display server metrics in
readable way.

The package can be installed by adding plug_server_timing
to your list of
dependencies in mix.exs

{:plug_telemetry_server_timing, "~> 0.1.0"}
]
end
Then add Plug.ServerTiming
to your pipeline BEFORE any Plug.Telemetry
definitions:
plug Plug.Telemetry.ServerTiming
plug Plug.Telemetry, event_prefix: [:my, :plug]

{[:my, :plug, :stop], :duration}
])
