GTM - debug topology load balancing

Hi Guys.

 

I have setup some Wide IPs and am using Topology load balancing.

 

I have noticed that sometimes DNS requests don't hit the topology load balancing. Just wondering if there is any way to 'debug' topology load balancing so I can see whats really happening?

    write an irule to make the selected region and log the info, either use an if or switch with an else/default to log catch data

    There's not a lot available with regards to topology debugging that I'm aware of. I had similar issues, and the problem was the topology records themselves.

     

     

    If you're attempting to do topology selection at the WideIP level, the target for the topology rule MUST be a Pool.
