You generally want all GTMs communicating with each other and all LTMs (not just local) via iquery. The GTM will delegate monitoring of virtual servers to the device that it thinks is best - in the case of virtual servers, it will delegate monitoring to the LTM on which they are configured.

From my experience, it is best to allow all GTMs to talk to all LTMs in order to have resilient monitoring. If my GTM in DC1 fails, I don't necessarily want all applications to fail to DC2.
