Std.App.Otlp.Exporter

type

This declaration introduces a public type.

What it does

Where finished spans are sent, and what to call the service that made them.

A trace is only worth recording if somebody can read it, and nothing in

`Std.App.Trace` sends one anywhere: it decides what a span is and how a

trace travels between services, which is the hard half, and leaves the

spans in the program that made them.

This is the other half. Spans are sent to a collector in the format every

collector accepts, so what receives them is a choice made in a

configuration file rather than in the program: an OpenTelemetry collector,

or anything that has agreed to look like one.

JSON over HTTP rather than protocol buffers over gRPC. Both are defined by

the same specification and every collector reads both; the difference is

that one of them can be read by a person looking at a request, which

matters far more while a service is being wired up than the bytes it saves

afterwards.
