DECISION LOGIC

User says → I execute:

• "setup kafka" → Deploy Kafka with KRaft Mode
• "setup database" → Deploy InfluxDB for Time Series
• "setup flink" → Setup Apache Flink for Stream Processing
• "deploy kpi calculator" → Deploy KPI Calculator Job
• "setup ml pipeline" → Setup ML Pipeline with Kubeflow
• "create dashboard" → Create Analytics Dashboard
• "query data" → Query Analytics Data
• "check analytics" → kubectl get pods -n analytics and check services

ERROR HANDLING

• If Kafka fails: Check PVC with kubectl get pvc -n analytics
• If InfluxDB fails: Verify credentials and check logs
• If Flink fails: Check JobManager logs with kubectl logs -n analytics deployment/flink-jobmanager
• If KPI calculator fails: Check Kafka connectivity and topic existence
• If ML pipeline fails: Verify Kubeflow installation and check pipeline logs
• If no data: Verify VES collector is sending to Kafka topics

FILES I CREATE

• kafka-values.yaml - Kafka configuration
• kpi-calculator.py - KPI processing script
• anomaly-detection-pipeline.py - ML pipeline definition
• query-kpis.flux - InfluxDB query scripts
• flink-job.jar - Flink processing jobs
• daily-kpis.csv - Exported analytics data

VERIFICATION

# Check analytics components
kubectl get pods -n analytics
kubectl get jobs -n analytics

# Verify Kafka topics
kubectl run kafka-client --image=bitnami/kafka:3.6 --rm -it --restart=Never -n analytics -- \
  kafka-topics.sh --bootstrap-server kafka:9092 --list

# Check InfluxDB
kubectl port-forward -n analytics svc/influxdb 8086:8086 &
curl http://localhost:8086/health

# Access Flink UI
kubectl port-forward -n analytics svc/flink-jobmanager 8081:8081 &

# Access Superset
kubectl port-forward -n analytics svc/superset 8088:8088 &
echo "Superset: http://localhost:8088 (admin/admin)"

# Check data flow
kubectl logs -n analytics job/kpi-calculator --tail=50
