Event log

The event log stores information about all significant events that occur in the system. It is useful to view logged information if unwanted behavior occurs in the system and you want to find out where the problem originates or get additional details.

To view the event log, open the Event log application.

Event log overview

Find relevant events

When investigating issues or errors in the system, try to examine the Source and Event code of logged events. These two properties uniquely describe the nature of the event in most cases. For more information, select specific events in the log and view their full Description or other relevant properties.

The search bar allows you to find items with a source or event code matching the entered text. You can also Filter the list of events.

Configure the event log

You can configure the functionality of the event log in the Settings application. The following settings are available in the System → Event log category.



Event log size

Limits the maximum number of events stored in the Event log.

  • When exceeded by 10%, this percentage of the oldest events is deleted from the log in a batch. You can adjust the percentage using the CMSLogKeepPercent configuration key (via the project’s appsettings.json file).
  • Old events that exceed the limit are not deleted immediately but only after a new event is logged.
  • Set the value to 0 if you do not want the system to log any events.

Log object and page actions

If enabled, basic create, edit, and delete actions for Xperience objects and pages are logged in the Event log.

Log to database

Does not apply if the Event log size setting is 0.

Log to file system

Indicates if events are logged to an App_Data\logEvents.log file in the project directory.

Does not apply if the Event log size setting is 0.
