OpenTelemetry Collector deployment, configuration, and troubleshooting for Coralogix users. Use when writing or debugging collector configs — the `coralogix` exporter (`domain:` vs `endpoint:`, `${env:CORALOGIX_PRIVATE_KEY}` bracket syntax, `coralogix/resource_catalog` variant), the universal processor chain, agent → cluster-collector → gateway topology, spanmetrics/tail_sampling/k8sattributes placement, component stability checks, data-safety/redaction routing including `url_sanitizer`, `sanitize_span_name`, `allow_all_keys`, and before/after validation for broad sanitizer over-sanitization, spanmetrics cardinality protection, and Coralogix-specific presets. Covers the `otel-integration` Helm chart (EKS/GKE/AKS/ OpenShift, GKE Autopilot Warden, EKS Fargate), ECS EC2 daemonset, ECS Fargate sidecar, Linux/Windows/macOS standalone, Docker, and the universal installer. Not for OTTL authoring (use the `opentelemetry-ottl` skill) or OpAMP supervisor/Fleet Manager internals beyond the config-precedence callout.
