Monitor Nginx with OpenTelemetry Tracing
At 3:47 AM, your NGINX logs show a 500 error. Around the same time, your APM flags a spike in API latency. But what's the root cause, and why is it so hard to correlate logs, traces, and metrics? When API response times cross 3 seconds, identifying whether the slowdown is at the NGINX layer, the application, or the database shouldn't require guesswork. That's where OpenTelemetry instrumentation for NGINX becomes essential.
