eventuo11y: An event-oriented observability library

Instrument your Haskell codebase with wide, semantically meaningful events. This library is designed with separating the following concerns in mind:

Writing instrumentation

When instrumenting code, I want to think in terms of my application domain and report any information I might need to infer internal application-level state and understand the behavior of my program/library.

Consuming instrumentation

When consuming instrumentation, I want to think in terms of the API fo the specific backend I'm supporting (writing to stderr, serving a Prometheus page, posting to OpenTelemetry) and what is needed to render to that API.

Initializing instrumentation in an application

When I'm ready to tie it all together, I want to identify the specific backends I want to post to and provide the bridge code to render the domain-specific instrumentation as needed for those backends. I also want to handle concerns like sampling or client-side aggregation of domain-specific instrumentation to keep usage manageable.

See Observe.Event for detailed documentation on instrumenting your code.

See Observe.Event.Backend for documentation on writing an EventBackend.

See Example.hs for an example.

See eventuo11y-batteries for miscellaneous framework-specific helpers.
