Summary
In this chapter, we covered some essential strategies to effectively monitor both the core Airflow system and individual DAGs post-deployment. We highlighted the importance of active and suppressive monitoring techniques and provided insights into the critical metrics to track for each component, including the scheduler, metadata database, triggerer, executors/workers, and web server. Additionally, we discussed logging, alerting mechanisms, SLA monitoring, and performance profiling techniques to ensure the reliability, scalability, and efficiency of Airflow workflows. By implementing these monitoring practices and leveraging the insights gained, operators can proactively manage and optimize their Airflow deployments for optimal performance and reliability.
In the next chapter, we’ll begin discussing multi-tenancy in Airflow and how it can be achieved in different ways.
