I am a consultant for a large company with over 1000 servers. Recently, a server hung on a reboot from a patch exercise. The problem is, we didn't know about it. Nothing reported it as not being available for client access. We could ping it. Our patching software and our Tivoli (of which I know NOTHING about) didn't report it either.
Our boss asked if there was a simple way to access the servers after a reboot to make sure that they were available. I thought about other programs and utilities, but I could not come up with any way to GUARANTEE that the server was available outside of mapping a drive on each one which is unrealistic and too time consuming.
I got to thinking that the PERFECT tool would also be able to report if the server has frozen, and we could tell the users before they found out (good P.R. right??)
So, Experts, what is the best way to report TRUE avialability of a server?
