Hi,
it looks that you have configured a rule to get infos about your vSphere environment with the special agent vSphere but the configured rule is also matching the windows host, where you want to get the checkmk agent data.
Take a look at that rule " Setup - Agents - VM, Cloud, Container - VMWare ESX via vSphere" and fix it to only match your vCenter and/or ESXi Hosts, depending on what you are trying to achieve.
