g-andrade/deigma

Deigma is an Erlang/OTP library designed for continuous event sampling within one-second time windows. It dynamically adjusts sampling percentages to respect rate limits while preserving the context of the original event population. The system provides a supervision tree and API for managing named event categories, ensuring consistent sampling behavior across different configurations.

The repository has been restructured and renamed to 'deigma', introducing an Erlang/OTP library for continuous event sampling. The library allows users to sample events within one-second windows, adjusting sampling percentages to honor rate limits while providing the original population context. It supports OTP 24 through 29, uses a modern rebar3-based build system with \erlfmt\ and static analysis tools, and generates EEP-48 native documentation.

The project has been renamed from bottlenape to deigma and introduced as a new Erlang/OTP library for continuous event sampling. It samples reported events within one-second windows, adjusting the sampling percentage to honor rate limits while exposing the sampling rate to downstream consumers. The library provides a supervision tree and API (start\_link, child\_spec, ask) to manage named event categories, with a default maximum rate limit of 100 events per window.

src · high confidence

Added a new Common Test suite (deigma\_SUITE.erl) that exercises the deigma application's core sampling functionality. The tests verify the \deigma:ask/3\ and \deigma:ask/4\ APIs across various event type counts and maximum rate configurations, ensuring correct sampling decisions and timestamps. It also includes specific tests for default and custom event functions, as well as validation of error handling when event functions throw exceptions or exit.
