Module domains 

Per-domain resolved config, grouped by ownership domain. Each field is owned by exactly one subsystem; cross-cutting values live in shared instead.

Modules

checks

Checks domain. Carries the checks IPC endpoint; the checks metrics-encoding settings live in shared.metrics_encoding.

dogstatsd

DogStatsD domain: source listeners, parsing, origin detection, aggregation, mapping, filters (some dynamic-capable), and debug logging.

multi_region_failover

Multi-Region Failover domain. Self-contained: it carries its own failover endpoint (api_key, site, dd_url), distinct from the primary forwarder endpoint in shared.endpoints.

otlp

OTLP domain: the OTLP receiver (gRPC/HTTP transports, logs/metrics activation), the OTLP proxy gating, and OTLP context sizing. OTLP trace handling lives in the traces domain.

traces

Traces domain: APM trace processing, including environment, sampling, and obfuscation.
