Adopting OpenTelemetry across 200+ services took us 4 months. The incremental, non-disruptive approach is the only one that works at scale.
Start with auto-instrumentation for the top 20 services by traffic. Deploy the OpenTelemetry Collector as a DaemonSet alongside existing monitoring. Run both systems in parallel for 30 days. Migrate dashboards one team at a time.
"The goal isn't to adopt OpenTelemetry. The goal is to understand your system better."
