### 17.3.3. Debug Logging by Service

OpenAM lets you capture debug log messages selectively for a specific service. This can be useful when you must turn on debugging in a production system where you want to avoid excessive logging, but must gather messages when you reproduce a problem.

Perform these steps to capture debug messages for a specific service.

1. Login to OpenAM console as administrator, `amadmin`.

2. Browse to `Debug.jsp`, for example `http://openam.example.com:8080/openam/Debug.jsp`.

   No links to this page are provided in the console.

3. Select the service to debug and also the level required given the hints provided in the `Debug.jsp` page.

   The change takes effect immediately.

4. Promptly reproduce the problem you are investigating.

5. After reproducing the problem, immediately return to the `Debug.jsp` page, and revert to normal log levels to avoid filling up the disk where debug logs are stored.
