Table of Contents

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
