# `ScoutApm.Instruments.LiveViewTelemetry`

Telemetry handler for Phoenix LiveView instrumentation.

Attaches to LiveView telemetry events to track:
- LiveView mounts (as "LiveView" type transactions)
- handle_event callbacks (as timed layers within transactions)
- handle_params callbacks (as timed layers within transactions)

## Usage

In your application's `start/2` function:

    def start(_type, _args) do
      ScoutApm.Instruments.LiveViewTelemetry.attach()
      # ... rest of supervision tree
    end

This will automatically instrument all LiveView modules in your application.

# `attach`

Attaches telemetry handlers for LiveView events.

Call this once during application startup.

# `detach`

Detaches the telemetry handlers. Useful for testing.

# `handle_event`
