You can integrate Airflow with a monitoring tool such as Prometheus or Grafana. These tools provide advanced monitoring and alerting capabilities. You can configure thresholds and receive alerts when the job runtime exceeds the specified limit.
Alternatively, you can use a dedicated job monitoring tool like Apache Oozie or Azkaban, which also offer alerting mechanisms to monitor long-running jobs. These tools provide more comprehensive job management features and can be integrated with Airflow.
