Type	Description
`Callable<T>`	A wrapped callable that includes attempt-level metrics recording.

buildMetricAttributes(String methodName, String status)

public static Map<String,String> buildMetricAttributes(String methodName, String status)

Method to build a map of attributes to be used across both operation and attempt level metrics.

Parameters
Name	Description
`methodName`	`String` The name of the API method.
`status`	`String` The status of the operation or attempt.
