# Activating AEL logging

AEL logging is installed and activated by default. To deactivate AEL logging, you will need to modify the `application.properties` file as described in the following instructions. Verify that you have the appropriate permissions to read, write, and execute commands in the following directories in the instructions.

1. Log on to the cluster and stop the AEL daemon.
2. Navigate to the `design-tools/data-integration/adaptive-execution/config` directory and open the `application.properties` file.
3. Locate the following line of code: `logging.config=./config/logback.xml`
4. Add comment tags for this line of code.
5. Save and close the file.
6. Restart the AEL daemon.

See the **Administer Pentaho Data Integration and Analytics** document for more information about the AEL daemon.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/advanced-topics-pentaho-data-integration-overview/adaptive-execution-layer-cp-landing-page/ael-logging-cp/activating-ael-logging.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
