An RPC spike hit 2 seconds inside Envoy, not the code. Debugging high latency uncovers mesh bottlenecks and shows how tracing and concurrency slash P99…
LLM latency spikes expose ms and CPU overhead from direct instrumentation. The sidecar proxy pattern isolates telemetry, slashing debugging time and lower costs.
Double‑billing complaints? The outbox pattern Kubernetes writes billing events inside the DB transaction, guaranteeing delivery and slashing audit‑headaches.
When your Go batch job stalls at 70% CPU but shows 0 mCPU, CPU throttling silently kills performance. Spot, instrument, and fix it in Kubernetes.
Silent AI agent failures bleed revenue while Kubernetes shows green status. Use OpenTelemetry instrumentation to catch logic hangs and LLM timeouts before sales notices.
