Apache Airflow is an open-source platform used to programmatically author, schedule, and monitor workflows. It is designed to orchestrate complex computational workflows and data processing pipelines. Airflow allows users to define tasks and their dependencies as code, ensuring that workflows are dynamic and can be easily maintained and monitored.
The AirflowWebserverHighLatency alert indicates that the Airflow webserver is experiencing high latency. This can affect the responsiveness of the Airflow UI and may lead to delays in accessing task logs, DAGs, and other critical information.
The Airflow webserver is a crucial component that serves the web UI, allowing users to interact with their DAGs and monitor task execution. High latency in the webserver can be caused by several factors, including network issues, server overload, or inefficient configurations. This alert is triggered when the response time of the webserver exceeds a predefined threshold, indicating potential performance bottlenecks.
To resolve the AirflowWebserverHighLatency alert, follow these steps:
Check for any network-related issues that might be causing latency:
Examine the server's resource utilization:
top
or htop
to monitor CPU and memory usage.iostat
or vmstat
.Review and adjust the webserver configurations:
airflow.cfg
file:[webserver]
workers = 4
worker_timeout
is set appropriately to prevent workers from timing out prematurely.Limit the number of concurrent requests to the webserver:
By following these steps, you can address the AirflowWebserverHighLatency alert and improve the performance of your Airflow webserver. Regular monitoring and optimization are key to maintaining a responsive and efficient Airflow environment. For more information on configuring Airflow, visit the official Airflow documentation.
