BIGIP DNS traffic flow

Hi

Like we can see 2 TCP connections( i.e. full proxy) on LTMs via show sys connections command; how can we see incoming DNS requests for Wide IPs (along with source IP details etc.) configured on BIGIP DNS systems which are in sync and hosted on different data centers.

 

Thanks

    Trying to workout what you're actually asking here. Do you mean there's no logging on the DNS queries that hit BigIP GTM? What I used to do was drop an iRule onto the VS and use it to log the requests and the responses.

      Precisely looking for BIGIP DNS command line options to look at these details ( incoming DNS requests to wide IPs, source IP etc. to which VS it was resolved )..Please advise.
