# Configure logging

Remote Execution Agents generate task logs in your Kubernetes cluster. By default, these logs remain in agent Pods and are lost when Pods terminate. Configure logging to preserve and access these logs.

<Note>
  **Airflow 3**

  This feature is only available for Airflow 3.x Deployments.
</Note>

## Logging approaches

### External logging provider (recommended)

Export logs to your logging platform (Splunk, Elasticsearch, CloudWatch, etc.) using a logging sidecar. Configure the Airflow UI to display links to external logs.

* See [Configure logging sidecar](/docs/astro/remote-agents-logging-sidecar)
* See [Export logs to external platforms](/docs/astro/remote-task-logs-external)

### Object storage (Airflow UI display)

Store logs in object storage (S3, GCS, Azure Blob) and configure the Astro API server to fetch and display them in the Airflow UI. Logs appear after task completion.

* See [Display logs in Airflow UI](/docs/astro/remote-task-logs-af-ui)

### Real-time streaming to object storage

Extend object storage logging with a Vector sidecar to stream partial logs while tasks run. Provides real-time log visibility in the Airflow UI.

* See [Display logs in Airflow UI](/docs/astro/remote-task-logs-af-ui#display-task-logs-during-task-execution)

## Comparison

| Feature              | External Logging          | Object Storage          | Real-Time Streaming       |
| -------------------- | ------------------------- | ----------------------- | ------------------------- |
| **Data location**    | Your logging platform     | Your object storage     | Your object storage       |
| **UI experience**    | Link to external platform | View in Airflow UI      | View in Airflow UI (live) |
| **Log availability** | Near real-time            | After task completion   | During task execution     |
| **Setup complexity** | Medium                    | Medium                  | High                      |
| **Storage costs**    | Platform-dependent        | Standard object storage | Higher (many small files) |

## Prerequisites

* Remote Execution Agent installed and registered
* Workload identity configured for your Kubernetes cluster
* One of the following:
  * **External logging**: Logging platform endpoint
  * **Object storage**: S3, GCS, or Azure Blob container
  * **Real-time streaming**: Object storage + Vector configuration
