Configure User Service communication
Click the User Service Connection button, then use the User and group update interval field to indicate how often Log Server connects to User Service to retrieve full user name and group assignment information (ever 12 hours, by default).
Activity for a user whose user name or group information has changed continues to be reported with the original user name or group assignment until the next update occurs.
Organizations that update their directory service frequently or have a large number of users should consider updating the user/group information more frequently.
