### 3.14.1 Managing Log Intervals

Use the Manage Log Interval page to set the minimum number of days to retain log information for log files.

To manage the log interval:

1. Sign in to Administration Services.
2. Click Manage Instance.
3. Under Manage Logs and Files, click Manage Log Interval.

   The Manage Log Interval page appears displaying the following logs:

   - Access Log - Records authentication events by developers and administrators accessing the APEX environment and by end users of APEX applications that use the built-in login APIs available to developers.
   - Activity Log - Records application page views including page submit actions and partial page refreshes. Application logging must be enabled.
   - Automation - Records execution of automations defined in applications.
   - Debug Messages Records - Debug messages emitted by applications while debugging is enabled.
   - Events - Records operational events performed by instance administrators. You can view these events in the Administrator Digest or by querying `APEX_EVENTS_LOG` dictionary view.
   - External Click Count Log - Counts clicks from an application to an external site. You can implement this functionality using the `APEX_UTIL.COUNT_CLICK` procedure.
   - REST Synchronization - Records details of previously executed REST synchronizations.
   - Web Service - Records all web service requests initiated from the APEX instance if web service activity logging is enabled.
4. For each log, enter the duration of the interval in days.

   The maximum value that can be specified is 180 days, with a default value of 14 days. Keeping log information for longer periods can degrade runtime performance.

5. Click Apply Changes.

### 3.14.4 Deleting Page View Activity Log Entries

Delete Page View Activity log entries. Page View Activity Logs track user activity for an application.

The APEX engine uses two logs to track user activity. At any given time, one log is designated as current. For each rendered page view, the APEX engine inserts one row into the log file. A log switch occurs at the interval listed on the Page View Activity Logs page. At that point, the APEX engine removes all entries in the noncurrent log and designates it as current.

Tip:

Developers enable logging within their application using the Logging attribute on the Edit Application Definition page. See Editing the Application Definition in Oracle APEX App Builder User’s Guide.

To delete Page View Activity log entries:

1. Sign in to Administration Services.
2. Click Manage Instance.
3. Under Manage Logs and Files, click Page View Activity Log.
