Modern cloud applications often operate as unmodified third-party services or legacy code, where direct instrumentation for observability is infeasible. This paper investigates whether a minimal black-box observability pipeline can still provide actionable insights in such contexts. We compose a standard stack—Envoy proxy, OpenTelemetry Collector, Prometheus, Jaeger, and Grafana—to collect metrics and traces without modifying application code, and we apply it to two representative workloads: a lightweight demo service and the OWASP Juice Shop. Our evaluation shows that proxy-only instrumentation captures meaningful demand and latency signals, that exported spans faithfully reflect traffic bursts visible in proxy metrics, and that distributed traces reveal endto- end error paths (e.g., 404 failures). These findings indicate that a carefully orchestrated open-source stack can approximate the diagnostic value of white-box instrumentation. The contributions of this work are a reproducible pipeline design and an empirical assessment demonstrating how such a configuration can reduce mean-time-to-detect (MTTD) failures and support service-level objective monitoring under synthetic load scenarios.
