The DCD can not handle the amount of statistic records sent by a single BIG-IP's avrd, if the amount of statistics exceeds system limit.
Agent Manager process on the DCD gets "high water mark" at its source buffer, and new statistics are lost.
A single BIG-IP produces a high volume of statistic records by the avrd module. Adding more DCDs will not help as single BIG-IP can only be connected to single DCD.
None
The DCD can now receive almost twice the amount of statistics rate than before, reducing the likelihood of data loss.
