From fd59e6660f747e5a8eac4cf4e9a3903e2806591f Mon Sep 17 00:00:00 2001 From: npub1mn7jgtj4w2pd0g0zeuhxsa6jy6p0rewxz4kujt98my82ahfmp72sxjexk7 Date: Tue, 30 Jun 2026 14:03:45 -0400 Subject: [PATCH] test(otel): add E2E harness for relay OTEL export surfaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a one-command local E2E that proves both observability export surfaces introduced in PR #1398: (a) Prometheus /metrics: buzz_ws_connections_total, buzz_events_received_total, buzz_auth_attempts_total present with non-zero values; target_info absent (suppressed via PR #1398). (b) OTLP traces: ws.auth and ws.event spans arrive at the collector carrying conn_id attribute and service.name=buzz-relay resource. (c) OTLP metrics: collector receives data tagged service.name=buzz-relay. (d) OTLP-disabled control: with OTEL_EXPORTER_OTLP_ENDPOINT unset /metrics still serves correctly; collector receives nothing. Architecture: relay runs on the host (matching the existing host.docker.internal Prometheus pattern); an otel-collector container added via compose overlay receives OTLP on :4317. The collector image is distroless so the output dir is bind-mounted to the host rather than read via docker exec. The Rust assertions in buzz-test-client read the host path directly.
