1. A computer-implemented method comprising: implementing, by a computing device, a structured logging service; exposing, by the structured logging service, a structured logging application programming interface (API) that implements trace event parameters; receiving a call to the structured logging API from an instrumentation point that is implemented within an application, the call supplying trace event arguments for the trace event parameters, wherein the trace event arguments include a structured payload containing one or more strongly-typed key-value pairs; capturing the structured payload as structured trace event information; and outputting the structured trace event information to one or more consumers, wherein a portion of the structured trace event information that corresponds to the structured payload is output as a serialized string or as the one or more strongly-typed key-value pairs.
