Struct Observability 

pub struct Observability {
    pub admin_addr: Option<String>,
    pub access_log: bool,
    pub otlp_endpoint: Option<String>,
}

Operational observability config ([observability], ADR 000009 Stage A): a separate admin listener exposing Prometheus metrics + liveness/readiness, and an opt-in structured access log. Off by default — Plecto stays quiet and exposes nothing extra unless asked (operational simplicity). Captured at construction; a reload does not re-bind the admin listener.

Fields

admin_addr: Option<String>

host:port the admin endpoint binds (e.g. 127.0.0.1:9090). None = no admin listener (the default). Serves /metrics, /healthz, /readyz — never on the data-plane port, so proxied routes never collide with it and the metrics surface is not exposed to clients.

access_log: bool

Emit one structured access-log event per request (the plecto::access tracing target, rendered as JSON by the binary’s subscriber). false by default.

otlp_endpoint: Option<String>

OTLP/HTTP collector base URL (e.g. http://localhost:4318) — the exporter appends /v1/traces, mirroring OTEL_EXPORTER_OTLP_ENDPOINT semantics (ADR 000040). None = no trace export (the default). Captured at construction, like admin_addr: changing it requires a restart, not a reload.
