+Audit Logs in Airflow
+========================
+
+
+Overview
+---------
+
+Audit logs are a critical component of any system that needs to maintain a high level of security and compliance.
+They provide a way to track user actions and system events, which can be used to troubleshoot issues, detect security breaches, and ensure regulatory compliance.
+
+In Airflow, audit logs are used to track user actions and system events that occur during the execution of DAGs and tasks.
+They are stored in a database and can be accessed through the Airflow UI.
+
+
+Level of Audit Logs
+--------------------
+
+Audit logs exist at the task level and the user level.
+
+- Task Level: At the task level, audit logs capture information related to the execution of a task, such as the start time, end time, and status of the task.
+
+- User Level: At the user level, audit logs capture information related to user actions, such as creating, modifying, or deleting a DAG or task.
+
+
+Location of Audit Logs
+----------------------
+
+Audit logs can be accessed through the Airflow UI. They are located under the "Admin" tab, and can be viewed by selecting "Audit Logs" from the dropdown menu.
+
+
+Types of Events
+---------------
+
+Airflow provides a set of predefined events that can be tracked in audit logs. These events include:
+
+- ``action_trigger_dag``: Triggering a DAG
+- ``action_create``: Creating a DAG or task
+- ``action_edit``: Modifying a DAG or task
+- ``action_delete``: Deleting a DAG or task
+- ``action_failed``: Setting a task as failed
+- ``action_success``: Setting a task as successful
+- ``action_retry``: Retrying a failed task
+- ``action_clear``: Clearing a task's state
+
+
+In addition to these predefined events, Airflow allows you to define custom events that can be tracked in audit logs.
+This can be done by calling the ``log`` method of the ``TaskInstance`` object.
