OpentelemetryLiveView uses telemetry handlers to create OpenTelemetry spans for LiveView mount, handle_params, and handle_event. The LiveView telemetry events that are used are documented here.

Usage

Add in your application start function a call to setup/0:

def start(_type, _args) do
  # this register a tracer for your application
  OpenTelemetry.register_application_tracer(:my_app)

  # this configures the liveview tracing
  OpentelemetryLiveView.setup()

  children = [
    ...
  ]

  ...
end
