Using Snowplow’s event pipeline and trackers, you can implement this capability with granular, first‑party data and real‑time processing. 

To monitor and troubleshoot a real-time event-driven data pipeline:- Use monitoring tools like Prometheus or Grafana to track system performance and metrics like message lag, throughput, and error rates.- Implement logging to track event processing stages and identify failures.- Use alerting systems to notify operators of issues, such as slowdowns or failures in message processing.- Regularly test the pipeline and validate data at various stages to ensure accuracy and reliability.
