Normal virtual server vs subserver

Hello, little question: if i use the subserver feature, can i monitor each single subserver?

Example: one of the subserver go hacked and start consuming 100% cpu. Is it easy for me see which subserver is? or it show the entire account?
I want see which subserver consume the most bandwitch… can i?

all statistic are for subserevr or for account?

so… final question: if the owner is the same person is better do 10 virtual server account or 1 account with 9 subserver?

p.s. sorry for my english :slight_smile:
