We were updating BIG-IQ from 5.4 to 7.1 via 6.1 (direct update was not possible due to timeout issue with the DCDs). All our BIG-IP devices are running on 184.108.40.206. We have a single BIG-IQ CM and a two node DCD-cluster.
The "Stats Last Collection Date" on BIQ-IQ shows "Jan 01, 1970 01:00:00(CET)" for all BIG-IP devices.
AVR module is provisioned on the devices and we also tried to fully remove the device and add with rediscover/reimport, but still the same behavior.
Any idea how to further troubleshot this or what's the reason for this?
Ciao Stefan 🙂
Have you checked and followed this as there is only info how to migrate statistics ?:
thanks for the link, but there they referring to a minimum of a three-node DCD-cluster.
We just have two DCD-nodes.
Do you have any experiences, if we missed the "Prepare statistics for upgrade" script?
From what I found out so far, it looks like, that since 13.1 BIG-IQ is not polling the statistics anymore, but the BIG-IP will push it via the AVR-module. Might this be a problem for FW-rules as the direction changes? I can't remember correctly anymore, but last Friday it looks like that there are just SYN-pakets on the BIG-IP devices towards the DCDs, which would confirm the FW-topic.
Or do you have maybe any other ideas, which logs I can check or which commands might provide useful output?
Ciao Stefan 😉
For the BIg-IQ and the AVR module check :
The BIG-IP system now pushes statistics data to BIG-IQ DCD (f5.com)
For the missing statistics check the article below (wait for 4 days before again triggering the script):
Also check if DCD is also on version 7.1 as they may not have been upgraded automatically:
It looks like we have the following two issues:
We are currently adjusting these issues and will report back once implemented.
