name	opentelemetry-collector-config-review
description	Use this skill for OpenTelemetry Operator review covering OpenTelemetryCollector deployment modes (Deployment, StatefulSet, DaemonSet, Sidecar), Instrumentation CR auto-instrumentation across Java/Node/Python/.NET/Go, Target Allocator for distributed Prometheus scraping, and pipeline correctness across receivers, processors, and exporters. Trigger when the user asks whether a collector configuration will lose telemetry, whether the right deployment mode is used, whether memory_limiter and batch are present, whether tail_sampling is safe to change, or whether auto-instrumentation will cover a workload after restart.

OpenTelemetry Collector Config Review

Purpose

Review OpenTelemetry Operator-managed OpenTelemetryCollector and Instrumentation resources against pipeline correctness, deployment-mode appropriateness, memory safety, sampling integrity, exporter security, and Kubernetes-attribute enrichment. Telemetry pipelines fail silently — a misconfigured exporter drops every span; a missing memory_limiter OOMs the collector; a deleted Instrumentation resource stops auto-instrumentation on next pod restart.

Lean operating rules

• Prefer live cluster evidence (kubectl get opentelemetrycollectors,instrumentations -A -o yaml plus collector logs and metrics) when the active client exposes it; otherwise fall back to official OpenTelemetry documentation (opentelemetry.io, opentelemetry-operator) and sanitized YAML.
