Hello,
It is my pleasure to announce the release of ocaml-opentelemetry 0.2. This library provides a core instrumentation library, as well as exporters, for the opentelemetry standard for observability; it encompasses distributed tracing, metrics, and (more recently) log export. A lot of tools are compatible with opentelemetry these days, including Grafana, DataDog, jaeger, etc.
This is still very early days for ocaml-opentelemetry, feedback and contributions are welcome.
Cheers!
