cargo add sova --features observability,observability-elasticsearch,observability-otel

Feature	What you get
observability	Prometheus /metrics.
observability-elasticsearch	Ship tracing logs to Elasticsearch.
observability-otel	OpenTelemetry OTLP export.

HTTP RED metrics (Prometheus) + optional OpenTelemetry / Elasticsearch logs for Sova.

 app.use_middleware(request_id());
 app.install(
     Observability::new()
         .with_elasticsearch() // ELASTICSEARCH_URL → bulk ship tracing logs
 );
 app.use_middleware(logger());

Declarative toggles also work via [observability] in sova.toml (metrics_path, otel, elasticsearch) when not set on the builder.

Usage

Presets already install request_id + logger. Add metrics/OTel explicitly:

let mut app = App::api().title("API").version("1.0").into_app();
app.install(Observability::new()); // GET /metrics
// order tip for custom stacks: request_id → Observability → logger
