DC Scope is installed in less than 15 minutes (the time of deploying the OVA). After that, it automatically starts collecting information from your datacenter.
DC Scope connects via API to the vCenter and ESX to collect the information of your datacenter. You don't need to install any agents on the VMs.
DC Scope is an on-premise solution. All the information, metrics, and analysis are stored and processed locally.
DC Scope does not make any changes to the infrastructure as it only requires Read-Only permissions from your vCenter.
