user account

Hello, I am a user of version 7.4.4 and I am populating the users in my cluster, and I would like to know how do I know which users are online?

Hi All, I have a 3 hosts cluster setup. I wanted to create a new user account "pveuser1" and give permissions similar to or almost similar to root user account. 1. Do i need to create pveuser1 in all 3 hosts? 2. How to give root permission to the user? Hope you get some replies.
