Understanding AEM Logs

AEM logs record various events that occur within the AEM system. These events can include system errors, user actions, system processes, and more. By examining these logs, you can gain insights into the system’s behavior, identify issues, and make necessary improvements.

Importance of AEM Logs

AEM logs are critical for several reasons:

  • Troubleshooting: Logs can help identify errors and issues in the system.
  • Performance Tuning: By examining logs, you can identify performance bottlenecks and optimize the system accordingly.
  • Security Audits: Logs can provide information about user actions, which can be useful for security audits.

Accessing AEM Logs through the File System

One way to access AEM logs is directly through the file system where your AEM instance is installed. Here’s how:

  1. Navigate to the AEM Installation Directory: The AEM logs are located within the AEM installation directory. The exact path can vary depending on your setup, but it typically looks like this: <AEM installation directory>/crx-quickstart/logs.
  2. Open the Log File: Within the logs directory, you will find several log files. The error.log file is the primary log file that records most of the system events.

Accessing AEM Logs through the AEM Web Console

Another way to access AEM logs is through the AEM web console. Here’s how:

  1. Open AEM: Launch your AEM instance.
  2. Navigate to the Web Console: In your web browser, navigate to the AEM web console. The URL typically looks like this: http://<your server>:<your port>/system/console/slinglog.
  3. Select the Log File: In the web console, you can select the log file you want to view.

Understanding Log Levels

AEM uses different log levels to categorize the severity of events. These levels, in order of increasing severity, are:

Log LevelDescription
DEBUGDetailed information for diagnosing problems.
INFOGeneral operational information about the system.
WARNPotentially harmful situations that are not yet errors.
ERRORIssues that have caused errors in the system.

Interpreting AEM Logs

When you open an AEM log, you’ll see lines of text detailing various events. Each line typically includes the date and time of the event, the log level, the name of the logger that recorded the event, and a message describing the event.

Working with AEM Logs

After accessing and understanding the AEM logs, you can use them to troubleshoot issues, optimize system performance, and conduct security audits. Remember to check the logs regularly to stay informed about your AEM system’s health.


AEM logs provide valuable insights into the functioning of your AEM system. By knowing how to access and interpret these logs, you can keep your AEM instance running smoothly and efficiently. Whether you’re troubleshooting an issue or looking to optimize performance, the AEM logs are a critical resource.
