Module documentation for 0.2.3.0

Core
- Core.Telemetry

Depends on 19 packages(full list with versions):

async, base, bytestring, chronologique, core-data, core-program, core-text, exceptions, http-streams, io-streams, mtl, network-info, random, safe-exceptions, scientific, stm, template-haskell, text, unix

This is part of a library to help build command-line programs, both tools and longer-running daemons.

This package in particular adds helpers for recording telemetry for subsequent analysis. You can instrument your code with tracing and spans, and also emit events carrying arbitrary metadata. Backends are provided for structured logs, sending traces to observability services, or even just outputting the telemetry to console.

See Core.Telemetry.Observability to get started.
