Published Works

This page contains some of the things I’ve published.


Three books currently bear my name. They look like this:

Nagios 1ed Nagios 2ed Ganglia

Evidently, I have a penchant for writing books with squiggly things on the cover.

Monitoring with Ganglia

The book on the far right, “Monitoring with Ganglia” was a not-for-profit cooperative effort by a group of Ganglia users and developers. I contributed Chapters 1, 2 and 7. I’m pretty happy with the result overall. If you’re on the fence, I can tell you, Chapter 5, which is about extending Ganglia’s metrics collection capabilities contains amazing documentation of gmond internals written by Brad Nicholes and is by itself worth the price of admission.

  • Chapter 1 is the only Chapter I wrote alone and is a pretty decent introduction to what Ganglia is and how it works.

  • Chapter 2 is boring installation and configuration stuff.

  • Chapter 7 is about integrating Ganglia with Nagios. Ganglia has pretty awesome Nagios integration, and this was a fun chapter to write.


The two Nagios books on the left are actually two editions of the same book, though the title, cover art, and ISBN have all changed. Quite a bit of new content and rewrite went into the second edition (they were published 6 years apart) including:

  • A new chapter on Scaling Nagios

  • A new Chapter on Nagios XI

  • A greatly expanded visualization chapter with case studies (of which I’m particularly proud)

  • Lots of updated info about plug-ins like Check_MK as well as integration info

  • A forward from Ethan Galstad. The man, myth, and legend.

I was particularly lucky in my technical reviewers this time around; they included Mike Guthrie who works for Nagios Enterprises, and wrote the Nagios XI PHP front-end, as well as Check_MK creator Mathias Kettner. So even if you already own the 1ed, the 2ed is probably worth your time if you happen to be a Nagios Admin who isn’t somehow trapped in the year 2004.

;login Magazine

I have, since around August of 2007, been writing a column for ;login magazine entitled iVoyer (yes the title was my idea, creepy right?). It’s mostly about systems monitoring but has a tendency to wander into other subjects like Greek mythology, cage fighting, grammer, science fiction, and home improvement. Eventually I’ll collect PDF’s of those articles here, but for now the link to the Usenix site above will have to do.
