JRahm, The end goal is to take action on the content of a DNS Express zone. We have anycast listeners that are up no matter the zone content. The desired behaviour is for the listeners to remain down (no tmm route) until the zone has managed a successful XFR.

 

The problem with iRules is that I'd like the code to run periodically, instead of traffic based. Icall can run periodically. Rather than looking at exact DNS queries I've explored the possibility of retrieving the number of records in a zone via tmsh::get_field, this works reliably and removes external triggers.
