Overview

The sensu-airflow-check is a Sensu Check that provides monitoring for airflow and DAGs.

Checks

This collection contains the following checks:

• airflow-check - for checking the health of the airflow metadatabase and scheduler.
• airflow-import-check - for checking DAG import errors.
• airflow-dag-check - for checking DAG runs for all or a specific list of DAGs.

Usage examples

airflow-check --url http://localhost:8080/

# Will check all loaded DAGs
airflow-dag-check --url http://localhost:8080/ --username admin --password admin

# Will check specific DAGs and will fail if one of the DAGs does not exist
airflow-dag-check --url http://localhost:8080/ --username admin --password admin --dag my_dag_id --dag my_other_dag_id

Configuration

The airflow API must be configured.
Typically, this means setting the following line in the [api] section:

auth_backend = airflow.api.auth.backend.basic_auth

Asset registration

Sensu Assets are the best way to make use of this plugin. If you're not using an asset, please
consider doing so! If you're using sensuctl 5.13 with Sensu Backend 5.13 or later, you can use the
following command to add the asset:

sensuctl asset add alasconnect/sensu-airflow-check

If you're using an earlier version of sensuctl, you can find the asset on the [Bonsai Asset Index][https://bonsai.sensu.io/assets/alasconnect/sensu-airflow-check].
