So you've got some high end servers running with some dual power supplies for ultra high availability. Great! Now here is the thing, when one of them fails, how will you know? Maybe it makes a beeping sound, but is that good enough?

It's not good enough for Tummy, we are all about proactive monitoring the health of our servers, from the power supply all the way up to the application (Plus I'm half-deaf and can't hear those beeps). I wrote an article on the technical aspects of how we do this, and shared the Nagios plugin I wrote for other sysadmins with similar hardware to use. Read the Article.

Ever fumbled around your house looking for a Linux CD, but you can't find it? Ever suspected that your ram was going bad, but you didn't have a way to test it? Ever needed to backup files on a computer that had a dead and broken operating system? A solution to all these problems is a super cool tool called PXE booting. PXE booting allows you to load alternative operating systems over the network, without the need for cds, cdroms, etc!

Sound like something that you could benefit from? Setting up your own PXE boot environment is easy and Fun! Check out my Journal entry and then later my wiki page for notes, commands, and configuration snippets to get your own setup going.
