Hi SynACk,
the sync group implements a concept of delegating monitoring / health checking (and config distribution).
This way a GTM typically monitors resources in the "local" data center and shares results with the other sync group members.
That´s why you can expect a failing monitor to be propagated to the whole sync group in real-time.
Just watch /var/log/gtm on all GTMs (
tail -f /var/log/ltm
) to verify it.
Btw, it is necessary that all GTMs are theoretically able to monitor all resources in your infrastructure. In case a "local" GTM becomes unavailable, another GTM takes the responsibility to monitor the related resources.
Thanks, Stephan
