You can read more about Citrix and MCS here: docs.citrix.com/en-us/tech-zone/design/reference-architectures/image-management.html#machine-creation-services
But actually, you do not need to know any details about MCS.
Think about a cloned VMs. The Site24x7 Agent on these cloned VMs should be personalized (reregister all VM IDs an UUIDs you are talking about) so that all created VMs from Master-Image will have different, individual Identities.
So we need a personalization-process, to prepare these Master-Images, for Cloning.
- delete all Site24x7 Agent data
- delete all unique files, IDs, UUIDs, Tokens etc.
- prepare the system, to recreate all this stuff after reboot!
The first time the Site24x7 Agents starts on a cloned VM, it should register itself as a new Monitor in Site24x7 platform.
I hope, this was clear enough.
