[0] 7. [Question] Does the agent-less system use XML-APIs, SNMP, etc? how does it work? [Answer] 
The monitored virtual server or ESX server cluster must be directly accessible by the SiteScope server (no proxy involved). The virtual server or ESX server cluster provides connection either by HTTP or HTTPS (depending on the VI server configuration). If HTTPS is used, the server certificate must be imported to SiteScope.
