Use apcupsd. Included with most distros. http://www.apcupsd.com/
I have configured it on several sites. It does just what you want - runs
a self test every so often, warns when the system goes on to battery and
performs a proper shutdown when there is only (say) five minutes power
left. And passes the 'yank out the mains cable and see what happens'
test with flying colours.

In a rack mount, go for PDUs with IEC connectors. Olsen are good.
Don't string up domestic power cable extensions.
