Settings - System

General
Default user ID	Specifies the user that serves as the system’s default global administrator. For example when indexing content for page crawler smart search indexes that are not configured to work under a specific user account. Enter the user ID of the given user. If empty, the system uses the default administrator user account.
Object code name prefix	A default prefix added to all object code names in the system. The prefix is added upon object creation.
Event log
Event log size	Limits the maximum number of events stored in the Event log. When exceeded by 10% (or a different percentage set by means of the CMSLogKeepPercent web.config key), the percentage of the oldest events is deleted from the log in a batch. Old events that exceed the limit are not deleted immediately, but only after a new event is logged. Applies separately to site-specific events for each site and global events. For example, if you set the limit to 100, the log may contain 110 site-specific events for each site in the system, and 110 global events. Set to 0 if you do not want the system to log any events.
Log metadata changes	Indicates if changes of object and page metadata (i.e. when an object or page is created, edited or deleted) are logged in the Event log.
Log to database	Indicates if events are logged to the database. Doesn’t overwrite Event log size set to 0.
Log to filesystem	If enabled, the system writes the event log into the *CMS\App_Data\logEvents.log* file on the server’s file system. Doesn’t override Event log size set to 0.
Log to trace	Indicates if events are logged to trace. Doesn’t overwrite Event log size set to 0.
Use EventLog trace listener	Indicates if the system logs events in your Windows Event Viewer. Use the Modify feature of the Kentico installer, if you haven’t turned on the Registration of Kentico in Windows Event Log option when installing Kentico.
Emails
No-reply email address	Various types of automated emails will be sent from the email address that is specified here.
Error notification email address	Email notifications about errors logged in the event log will be sent to the specified addresses. It is possible to enter multiple addresses separated by semicolons.
Send email notifications from	Email address used as the sender for email notifications.
Scheduler
Application scheduler interval	Determines how often the application checks if there are any tasks ready to be executed (in seconds). By default, the scheduler is configured to check tasks only on page requests. You can set the minimum time between the checks to any interval. If it is configured to check automatically, you can set an interval of 1 to 30 seconds. Setting 0 stops the scheduling of tasks.
Use external service	Indicates if scheduled tasks that have the Use external service option enabled are processed by the Kentico Scheduler Windows service. Note: for this to work, the service must be installed and running. If enabled and the service is not running, these tasks are not processed at all. If disabled, all scheduled tasks are processed by the application itself. You can install the service using Kentico Service Manager.
Service scheduler interval	Determines how often the external Windows service checks if there are any tasks ready to be executed (in seconds). You can set an interval of 1 to 30 seconds. Setting 0 stops the scheduling of tasks.
Scheduled tasks enabled	Scheduled tasks will only be executed if this setting is enabled.
Time zones
Enable time zones	Indicates if time zone support is enabled.
Server time zone	Specifies the time zone of the physical location of the server.
Site time zone	Specifies the time zone for the selected site.
User interface
Hide unavailable user interface	Indicates if the user interface is hidden for features unavailable due to license restrictions.
Max UI tree nodes	Maximum number of nodes displayed under one parent node in the administration UI trees. Any additional tree nodes will be accessible via the click here for more… option, which automatically selects appropriate parent category.
Remember listing, filter and state	If enabled, listing pages in the user interface remember the preferences set by individual users, including: filtering options sorting order the number of the selected page page size
Kentico improvement program
Send anonymous usage records to Kentico	By default, the application periodically sends data about the system’s usage to Kentico. The data helps Kentico analyze which parts of the system need improvement and allows us to better focus our development efforts. All of the data is strictly anonymous and for internal use only. See the Kentico improvement program page for more information. You can disable the setting to opt out of the Kentico improvement program and stop the sending of data.
