Unusually high AVR CPU utilization occurs following an upgrade.
AVR CPU utilization can be unusually high for an unusually long period of time.
-- BIG-IP software upgrade to v13.0.x or later. -- Running AVR.
After upgrade manually edit /etc/avr/avrd.cfg to decrease AVR CPU usage is high by increasing the time period of real-time statistics collection. In order to do so: 1. Change value of RtIntervalSecs in /etc/avr/avrd.cfg file to 30 or 60 seconds. 2. Restart the system by running the following command at the command prompt: bigstart restart. When changing RtIntervalSecs please take into consideration two important limitations: -- Value of RtIntervalSecs cannot be less than 10. -- Value of RtIntervalSecs must be 10 on BIG-IP devices that are registered on BIG-IQ DCD nodes.
