The connection is established in two steps:
- The XenServer pool master (or the XS configured in the hypervisor connection) - defined as HTTPS and brings metadata such as the host names and VM names.
- Following that connection we connect directly to each XenServer which is part of the pool - this connection is established via HTTP. By connecting directly to the RRDs and we get performance metrics directly from each XenServer. (via this address : http://<HOST>/rrd_updates?start=<TIME>&host=true)
