External URL monitoring with GTM

i want to monitor our externally hosted websites http://abc.com and http://xyz.com with GTMs in our environment. How can we do that ?

We have 2 datecenters already created and few servers configured under those Dc's. Now i want to create another server as generic host and allign to anyone of datacenter. IS IT RIGHT ?
