If you’re like me and most humans, the Nagios logfile timestamp (a unix timestamp) isn’t terribly useful when trying to grep through the logs and correlate events:

# head -2 nagios.log
[1350360000] LOG ROTATION: DAILY
[1350360000] LOG VERSION: 2.0

Here’s a nifty Perl one-liner that you …

In a previous post, I described how I do Secure rsnapshot backups over the WAN via SSH. While my layout of rsnapshot configuration files, data, and log files is a bit esoteric, I monitor all this with a Nagios check plugin that runs on my backup host. It Assumes that …

My wife Jackie (Syrilia) is an avid World of Warcraft player (it’s a MMORPG with over 10 million players). They have weekly server maintenance/update windows every Tuesday morning - total downtime. The length is never really fixed, so I looked around to see if there was a logical way …

Since I have most of my public-facing stuff hosted with Linode, and I have a monthly bandwidth cap (albeit one that I’ll probably never come close to), I decided that it would be a good idea to add my monthly bandwidth usage to my monitoring system. Luckily, Linode offers …

As you may know from former posts, this blog (WordPress-powered) and a few MediaWiki sites that I have use the excellent PHP-based GeSHi syntax highlighter. Today I was writing a post that includes some Icinga (Nagios) configuration snippets. After a quick search, I found a Nagios language file …

I’ve been doing some work on icinga (a Nagios fork) and wanted to implement notification via AOL Instant Messenger (AIM), since I’m almost always signed on when I’m at a computer. Unfortunately, most of the scripts that I could find use Net::AIM::TOC which implements a …

Last week I added some of my Nagios check scripts to my nagios-scripts GitHub repository. Perhaps they’ll be of some use to some other people…

• check_1wire_temps.php
  • quick and dirty, built for one specific application, but a good starting place for checking Dallas 1-wire temperatures via OWFS.
• check_802dot11.php …

A while ago (back in late 2008), I wrote a PHP script that parses the Nagios status.dat file into an associative array. My original use was to output …

No matter how much we may not like it, and no matter how insecure it can potentially be, we occasionally have to run Nagios check scripts (written in scripting languages) as root. (On a side note, this method is also used for my MultiBindAdmin project’s DNS file push). Here …
