package trace-tef

Trace

This small library provides basic types that can be used to instrument a library or application, either by hand or via a ppx.

Features

• spans
• messages
• counters
• other metrics?

Backends

Concrete tracing or observability formats such as:

• Fuchsia (see tracing)

• Catapult

  • light bindings here with trace-tef
  • richer bindings with ocaml-catapult, with multi-process backends, etc.
• Tracy (see ocaml-tracy, more specifically tracy-client.trace)
• Opentelemetry (see ocaml-opentelemetry, in opentelemetry.trace)
• landmarks?
• Logs (only for messages, obviously)
