Description:

This expands what is in the APM CE documentation on e-commerce mode and automatically assigning user groups to subnet user groups.

 

Issue:

In Automatically assigning new users to subnet user groups, the APM Configuration and Administration Guide states the following:

Important! If your installation is a large-scale e-commerce site (hundreds of thousands or millions of users), do not use this feature. The number of user groups created can become unmanageable.

However there are no details on the implications of doing this.

 

Solution:

The implications of having a user identifier for e-commerce mode includes the following:

  • A growing and bloated database due to large database partitions capturing login and session map information each hour.
  • An unresponsive APM CE MOM UI
  • A large number of active and inactive users (depending on data retention settings.)
  • Unusable reports
  • Filled EM logs showing session/log in activities including duplicate session ids
  • Filled Event tables of duplicate session ids.
  • Increased CPU utilization.

Removing the User/User Group identifier will take care of most of the above over time.
