Is this an issue? Is it a logging or observability issue, or something else that cannot be captured through logs?

Determining whether a problem is a logging or observability issue requires understanding what data is missing. If the application logs are complete but you still cannot see the root cause, the issue may be with log aggregation or retention—logs might be dropped or not forwarded to the central system. If logs exist but lack context, you may need richer observability: metrics to show system health trends and traces to follow request paths. A classic sign of an observability gap is intermittent failures that appear in logs but cannot be correlated with performance spikes or error rates. In such cases, instrument the code with OpenTelemetry to emit traces and metrics, and ensure that the monitoring stack aggregates them. If the problem persists even after adding metrics and traces, consider external factors like network latency, third‑party service outages, or infrastructure misconfigurations that logs alone cannot reveal.
