DO_NOT_USE_ENVIRONMENT_AGENT_SETTINGS =

NOTE: Due to… legacy reasons… This class likes having a default ‘AgentSettings` instance to fall back to. Because we generate this instance with an empty instance of `Settings`, the resulting `AgentSettings` below represents only settings specified via environment variables + the usual defaults.

DO NOT USE THIS IN NEW CODE, as it ignores any settings specified by users via ‘Datadog.configure`.

  Datadog::Core::Configuration::Settings.new,
