The Datadog Agent collects many metrics from Airflow, including those for:
Metrics are collected through the Airflow StatsD plugin and sent to Datadog’s DogStatsD.
In addition to metrics, the Datadog Agent also sends service checks related to Airflow’s health.
All steps below are needed for the Airflow integration to work properly. Before you begin, install the Datadog Agent version >=6.17 or >=7.17, which includes the StatsD/DogStatsD mapping feature.
There are two forms of the Airflow integration. There is the Datadog Agent integration which will make requests to a provided endpoint for Airflow to report whether it can connect and is healthy. Then there is the Airflow StatsD portion where Airflow can be configured to send metrics to the Datadog Agent, which can remap the Airflow notation to a Datadog notation.
Configure the Airflow check included in the Datadog Agent package to collect health metrics and service checks. This can be done by editing the url within the airflow.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory, to start collecting your Airflow service checks. See the sample airflow.d/conf.yaml for all available configuration options.
Connect Airflow to DogStatsD (included in the Datadog Agent) by using the Airflow statsd feature to collect metrics. For more information about the metrics reported by the Airflow version used and the additional configuration options, see the Airflow documentation below:
Note: Presence or absence of StatsD metrics reported by Airflow might vary depending on the Airflow Executor used. For example: airflow.ti_failures/successes, airflow.operator_failures/successes, airflow.dag.task.duration are not reported for KubernetesExecutor.
Install the Airflow StatsD plugin.
pip install 'apache-airflow[statsd]'
Update the Airflow configuration file airflow.cfg by adding the following configs:
[scheduler]
statsd_on = True
statsd_host = localhost # Hostname or IP of server running the Datadog Agent
statsd_port = 8125 # DogStatsD port configured in the Datadog Agent
statsd_prefix = airflow
Update the Datadog Agent main configuration file datadog.yaml by adding the following configs:
# dogstatsd_mapper_cache_size: 1000 # default to 1000

Use the default configuration in your airflow.d/conf.yaml file to activate your Airflow service checks. See the sample airflow.d/conf.yaml for all available configuration options.
Available for Agent versions >6.0
Collecting logs is disabled by default in the Datadog Agent. Enable it in your datadog.yaml file:
logs_enabled: true
Uncomment and edit this configuration block at the bottom of your airflow.d/conf.yaml:
Change the path and service parameter values and configure them for your environment.
Configuration for DAG processor manager and Scheduler logs:
logs:
- type: file
path: "<PATH_TO_AIRFLOW>/logs/dag_processor_manager/dag_processor_manager.log"
source: airflow
service: "<SERVICE_NAME>"
log_processing_rules:
- type: multi_line
name: new_log_start_with_date
pattern: \[\d{4}\-\d{2}\-\d{2}
- type: file
path: "<PATH_TO_AIRFLOW>/logs/scheduler/*/*.log"
source: airflow
service: "<SERVICE_NAME>"
log_processing_rules:
- type: multi_line
name: new_log_start_with_date
pattern: \[\d{4}\-\d{2}\-\d{2}
Regular clean up is recommended for scheduler logs with daily log rotation.
Additional configuration for DAG tasks logs:
logs:
- type: file
path: "<PATH_TO_AIRFLOW>/logs/*/*/*/*.log"
source: airflow
service: "<SERVICE_NAME>"
log_processing_rules:
- type: multi_line
name: new_log_start_with_date
pattern: \[\d{4}\-\d{2}\-\d{2}
Caveat: By default Airflow uses this log file template for tasks: log_filename_template = {{ ti.dag_id }}/{{ ti.task_id }}/{{ ts }}/{{ try_number }}.log. The number of log files will grow quickly if not cleaned regularly. This pattern is used by Airflow UI to display logs individually for each executed task.
If you do not view logs in Airflow UI, Datadog recommends this configuration in airflow.cfg: log_filename_template = dag_tasks.log. Then log rotate this file and use this configuration:
logs:
- type: file
path: "<PATH_TO_AIRFLOW>/logs/dag_tasks.log"
source: airflow
service: "<SERVICE_NAME>"
log_processing_rules:
- type: multi_line
name: new_log_start_with_date
pattern: \[\d{4}\-\d{2}\-\d{2}

Connect Airflow to DogStatsD (included in the Datadog Agent) by using the Airflow statsd feature to collect metrics. For more information about the metrics reported by the Airflow version used and the additional configuration options, see the Airflow documentation below:
Note: Presence or absence of StatsD metrics reported by Airflow might vary depending on the Airflow Executor used. For example: airflow.ti_failures/successes, airflow.operator_failures/successes, airflow.dag.task.duration are not reported for KubernetesExecutor.
Note: The environment variables used for Airflow may differ between versions. For example in Airflow 2.0.0 this utilizes the environment variable AIRFLOW__METRICS__STATSD_HOST, whereas Airflow 1.10.15 utilizes AIRFLOW__SCHEDULER__STATSD_HOST.
The Airflow StatsD configuration can be enabled with the following environment variables in a Kubernetes Deployment:
env:
- name: AIRFLOW__SCHEDULER__STATSD_ON
value: "True"
- name: AIRFLOW__SCHEDULER__STATSD_PORT
value: "8125"
- name: AIRFLOW__SCHEDULER__STATSD_PREFIX
value: "airflow"
- name: AIRFLOW__SCHEDULER__STATSD_HOST
valueFrom:
fieldRef:
fieldPath: status.hostIP
The environment variable for the host endpoint AIRFLOW__SCHEDULER__STATSD_HOST is supplied with the node’s host IP address to route the StatsD data to the Datadog Agent pod on the same node as the Airflow pod. This setup also requires the Agent to have a hostPort open for this port 8125 and accepting non-local StatsD traffic. For more information, see DogStatsD on Kubernetes Setup here.
This should direct the StatsD traffic from the Airflow container to a Datadog Agent ready to accept the incoming data. The last portion is to update the Datadog Agent with the corresponding dogstatsd_mapper_profiles . This can be done by copying the dogstatsd_mapper_profiles provided in the Host installation into your datadog.yaml file. Or by deploying your Datadog Agent with the equivalent JSON configuration in the environment variable DD_DOGSTATSD_MAPPER_PROFILES. With respect to Kubernetes the equivalent environment variable notation is:
env:
- name: DD_DOGSTATSD_MAPPER_PROFILES
