Opened: Jun 16, 2021

Severity: 2-Critical

Symptoms

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.

Impact

Agent Manager process on the DCD gets "high water mark" at its source buffer, and new statistics are lost.

Conditions

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.

Workaround

None

Fix Information

The DCD can now receive almost twice the amount of statistics rate than before, reducing the likelihood of data loss.
