F5 BIG-IP v13.1.1 AVR log

Hi all, I am not sure it is right place to put my question or not but any way I have an issue related to the AVR log add will be appropriate if somebody can help me.

 

In the new F5 BIG-IP version 13.1.1 logs there are filed that value have N/A value like ServerLatencyMax="N/A" so I would like to understated is it expected or it is result of configuration issue.

 

Another problems that the field in the logs separated by coma are different the in versions 12. So can somebody confirm the AVR log format does not changed from version 12 to version 13

 

Thanks, Andranik H.
