How to configure the site to automatically create user device affinities

 

Configuration Manager reads data about user logons from the Windows Event log. To be able to automatically create user device affinities, you must enable the following two settings from the local security policy on client computers to store logon events in the Windows Event log.

  • Audit account logon events
  • Audit logon events

 

Make sure that these events are logged in the security event logs.

https://technet.microsoft.com/en-in/library/cc787567(v=ws.10).aspx

 

To allow sufficient data for user device affinity, also set the policy Maximum security log size to a reasonable value such as 5-20 MB.

 

If we don’t have events in security events (log on events )the feature will not work

 

Once you have the UDA settings set in the client settings the same flows to the client as policy.

 

When the client goes through a log off or log on events  you would see  the following in the useraffinity.log

 

UserAffinity.log

Later when the affinity agent will run the affinity usage Task . This happens once in a day  or if we restart the ccmexec service

 

UserAffinity.log

3/5/2015 7:40:43 AM UserAffinity 3304 (0x0CE8) Auto affinity threshold settings Days = '1', User minutes threshold = '360', Auto approve affinity = '1'.

UserAffinityProvider.log

====================

3/5/2015 7:40:43 AM UserAffinityProvider 3972 (0x0F84) The state message store path is: 'C:\Windows\CCM\UserAffinityStore.sdf'

3/5/2015 7:40:44 AM UserAffinityProvider 3972 (0x0F84) GetAllInstances - 13 instance(s) of 'CCM_UserLogonEvents' found

3/5/2015 7:40:44 AM UserAffinityProvider 3216 (0x0C90) GetAllInstances - 13 instance(s) of 'CCM_UserLogonEvents' found

 

Once done it will create a state message which will send to the serve which will update the information ion the database

 

State message with TopicType 1600 and TopicId contoso/administrator_Auto and State 1 has been updated        StateMessage        3/5/2015 1:45:12 PM        4068 (0x0FE4)

 

State 1 means SET affinity

Sate 2 means REMOVE affinity

 

Now this state message flows as usual state message and insert in to the database

 

Hope this would be helpful.

    Let's say we change our UDA settings from 2880 minutes over 30 days to 1440 minutes over 15 days. Does UDA then look retroactively at the security event log to recalculate whether a user is primary or not?

    Hello.

    Similar to the above question, does UDA look at event logs retrospectively?

    Say we are migrating agents from 2007 to 2012, if UDA is enabled in 2012, and logon events are captured, will UDA be populated for 2012 immediately?

    additionally, just to confirm, Top Console User has no bearing on UDA?
