Everyone here is going to tell you that a human needs to be there because that is their livelihood. Any task can be automated at a cost. I am guessing that it is not your current task to automate maintenance tasks otherwise you wouldn't be asking. Somewhere up your chain they decided that for the uptime / quality of service it is more cost effective to have a human do it. That does not mean that you can not present a case showing otherwise. I highly suggest that you win approval and backing before taking time to try to automate anything.
Out of curiosity, are they VMs?
