[plug] ups driven automatic server shutdown

Hi All,

I am currently trying to find a good solution for the above problem. So far
all the options I have are either a lot of development or dont go far enough
into what I need.

What I am really after is something that can login to around 140 servers and
shut them down based on certain criteria, ie. applications and/or services
on a single machine need to come down in a specific order, check to make
sure they are down, if they aren't try bringing them down two more times
before forcefully killing the app/service. Once the server is brought down
the shutdown controller needs to check that it is uncontactable before
moving onto the next server. The servers need to have dependencies put next
to them in order for the controller to shut them down in a specific order.

I know I can do this on a linux server getting the results via snmp from the
UPS (as well as environmental alarms and or serial access to a power circuit
relay) and then use perl scripts to do the actual shutdown, however its more
work than I wanted to do and I was kind of hoping for a commercial solution
that can do the same thing using shutdown clients on each machine [ or
similar ]. I would really like the server to run on linux as we all know
Windows shouldn't be trusted to conduct such a sensitive task.

Anyone have any ideas?
