Class Method Details

.init_otel(sdk_version) ⇒ OtelState

Initializes OTel providers, sets globals, installs Typhoeus propagation. OTel gems are required lazily so they are never loaded when disabled.

Parameters:

  • sdk_version (String)

Returns:

.with_instrumentation(otel_state, component, method_name, &block) ⇒ Object

Wraps a block with OTel span creation and duration histogram recording. When otel_state is nil (OTel disabled), calls the block directly.

Parameters:

  • otel_state (OtelState, nil)
  • component (String)
  • method_name (String)

Returns:

  • (Object) —

    The block’s return value
