Bug Tracker

Affected Product:  See more info
BIG-IQ ADC(all modules)

Opened: Apr 19, 2022
Severity: 3-Major

Symptoms

A large number of LTM objects impacts the page load time for Device and Application statistics pages.

Impact

Page load time is high for the Device and Application pages.

Conditions

BIG-IQ is configured with a large number of LTM objects. This can include objects such as virtual servers, pools, nodes, and pool members.

Workaround

A property "dcdPollerVersion" has been added which has a value of 1 by default. 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) When implements, BIG-IQ uses the enhanced DCD stats-poller task, which improves the latency that impacts page load time.

Fix Information
