I've follow the document to scan the virtual center "https://www.lansweeper.com/knowledgebase/how-to-scan-a-vcenter-server/", but I'm stock in the last step when you had to assign the credential to the IP range. It just not apparear as an option in the pop menu, onlu Linux and windows ones.
You can add a vCenter scanning credential by going to the Scanning\Scanning Credentials tab and clicking the Add new Credential button.
For more information on creating and mapping scanning credentials, you can refer to the below article. https://www.lansweeper.com/knowledgebase/creating-and-mapping-scanning-credentials/
