What problem does it solve? Tuning Managed Service for Apache Airflow (Cloud Composer) environments is hard without data: teams often guess at scaling parameters, suffer unexplained scheduler or worker restarts, and overspend by blindly upsizing machines. This Skill gathers real telemetry from Cloud Monitoring and turns it into concrete, evidence-based recommendations. ## Core Features & Use Cases - Telemetry-Driven Diagnostics: Runs Python scripts that query Cloud Monitoring via PromQL for CPU, memory, disk usage, workload restarts, DAG parsing times, and overall environment health. - Structured Recommendation Workflow: Follows a five-step process covering context gathering, configuration inspection via gcloud, metrics collection, diagnosis, and categorized recommendations (infrastructure, Airflow config, bucket hygiene, production best practices). - Use Case: Your Airflow scheduler keeps restarting and DAGs are delayed. Ask the Skill to analyze your environment; it pulls restart counts, memory usage, and DAG parsing stats, then identifies an OOM issue and recommends specific memory limits and airflow.cfg overrides instead of a blind upgrade. ## Quick Start Analyze my Cloud Composer environment 'prod-airflow' in project my-gcp-project, region us-central1, over the past 24 hours and give me tuning recommendations.
