Symptoms

There is some performance issue between BIG-IQ and DCDs.

Impact

BIG-IQ is very slow to load the Device and Application pages.

Conditions

This happens when there is a large number of LTM objects (like thousands of VS, Pool, Node, pool-members).

Workaround

None

Fix Information

A property "dcdPollerVersion" has been added which has a value of 1 by default. To adopt this change, you must change the property from 1 to 2 by performing the following steps: 1. Get the stats-refresh config (GET https://your-big-iq/mgmt/cm/adc-core/current-config/stats-refresh) 2. Copy the JSON except "generation" and "lastUpdateMicros" 3. Create a PUT query with "dcdPollerVersion" value as 2 (in the JSON saved in step 2) (PUT https://your-big-iq/mgmt/cm/adc-core/current-config/stats-refresh) BIG-IQ will now use the enhanced DCD stats-poller task.
