NimbostratusGTM Monitoring pool from different DC
Hi I have two BIG-IP DNS in Active-Active, and when I make some captures the those big-ip only the probes comes out from the big-ip that it is in that DC to the services in that datacenter.
For examble DC A have (big-ip A and server A(Generic Host))
DC B have (big-ip B and server B(Generic Host))
The question is will big-ip B monitor services in server A ? because the only monitors that I get is from big-ip A to vs server A(Generic Host) and big-ip B to vs server B(Generic Host)
it is that normal?

it depends on your DNS service design objective.
As far as the DNS service itself is concerned, the DNS server does not need to monitor services in other DCs, as it only provides a DNS service from the DC it is located in. If it is down/unavailable, the downstream DNS servers and/or clients will notice and mark it down, and then goes on to use the DNS service provided from other DC.
