perl program for clusters

[usaims]

Hello:

I'm in the process of writing a program that I can put on an apache
server which tells me which clusters are in or out of a load balancer.
I deal with 3 clusters all day long, which at all times, 2 clusters are
in the load balancer. I would like my boss to go to a web page and see
green for two clusters and a red for the one that is out. But I would
like to put this in a timetable graph so that they can see which
clusters were in at a certain time. Can somebody give some 'keywords'
to look for in google because I really don't have a clue on where to
start. My Perl skills are adequate but a little push in the right
direction will be greatly appreciated.

It's easy to create HTML that shows what you describe. For example with
tables inside tables, and a colored bar per invisible cell, created by
scaling up a single green or red pixel. Please consult an HTML group. Or
look into RRD or RRDtool, see also CPAN.

I'd look at nagios.

I'd use MRTG (or RRDTool).
