Symptoms

When managed BIG-IP devices are configured in a DSC group, BIG-IQ does not collect statistics from all managed devices.

Impact

Statistics are not collected for all the managed BIG-IP devices. In addition, the managed BIG-IP devices get into an out-of-sync config state that is reported as a state that needs attention. -- A common symptom is the 'Stats Last Collection Date' shows up as Dec 31, 1969 or Jan 01, 1970, depending the timezone configuration of the device. -- The 'Stats Last Collection Date' shows up as '--'. -- The BIG-IP systems incorrectly identify themselves to BIG-IQ. -- The BIG-IP systems do not report at all, even if they are configured to report.
