Hi , Since it is very difficult to have look on all the servers u can have nagios setup through which u can monitor all the running services and u can also get notified by an email in case any service goes down. It is a very professional way to monitor your all your servers at once. I can also help u create custom nagios bash plugins for ur setups if u need.
