+     - A timestamp: the day and time (server time, not browser time) the system event or the user action occurred                            
+     - A message: type of the occurred event or user action.
+     - The user that triggered the event or performed the action. User system is used for events triggered by the system itself.</para>
+    <para>The right chevron icon in the activity log entry opens a modal with the activity metadata.</para>
+     <para>The Activity Log allows to filter by the type of event or user action, commonly refered to as resource type, and by the user that triggered the event or performed the action. Only active users are available for filtering.
+      The Activity Log also allows to filter out entries that are newer and/or older than an specific date and time. When setting time based entries, keep in mind the time difference with the server time.   -

+     <para>The pagination features at the bottom of the Activity Log allow the user to specify the number of entries to display in a page, scroll back and forth through the different pages of the view, and jump directly to the last 
+      page and back to first one.</para>
+     <para>The default retention time for entries in the Activity Log is one month. This can be changed in the Activity Log section under Settings. Changing the retention time requires the all:settings permissions. Entries expired after the specified retention time are deleted every day at midnight (server time).</para>
