Logging and Monitoring architecture

Airflow supports a variety of logging and monitoring mechanisms as shown below.

By default, Airflow supports logging into the local file system. These include logs from the Web server, the Scheduler, and the Workers running tasks. This is suitable for development environments and for quick debugging.

For cloud deployments, Airflow also has handlers contributed by the Community for logging to cloud storage such as AWS, Google Cloud, and Azure.

The logging settings and options can be specified in the Airflow Configuration file, which as usual needs to be available to all the Airflow process: Web server, Scheduler, and Workers.

For production deployments, we recommend using FluentD to capture logs and send it to destinations such as ElasticSearch or Splunk.

Similarly, we recommend using StatsD for gathering metrics from Airflow and send them to destinations such as Prometheus.
