It’s done. There is a book about Icinga 2 available as hardcopy (right now) and e-book (coming soon). There is only one minor drawback: It’s entirely in German. Since Lennart and me are German native-speakers, we decided it would be best to write the book in German, too. (In fact I’m Austrian, but Austrian is so similar to German that linguists still argue if it’s the same language or not)
But don’t you despair, if you can’t read German and don’t have the time to learn how to. We are still negotiating whether there will be an English version of the book or not. We will keep you updated.
If you are able to read German, here’s what is in the book:
Installation of Icinga 2 including the ClassicUI and Icinga Web 2
Thorough introduction to the Icinga 2 configuration language
Monitoring with the Icinga 2 agent, NRPE and SSH
Distributed monitoring with satellites
Best Practices about how to plan and implement a monitoring setup
100 pages about monitoring plugins
Graphing with Graphite and PNP
Logmanagement with Logstash
Appendices with lots of extra code examples
The whole book uses a fictional company for examples which are backed with actual code. The examples were not only tested in a test environment but some are taken out of actual setups from customers (We are Icinga consultants for a living)
So, if you want to order one (or more) book you can do so via Amazon, directly from the publisher or many other sources. E-books are still in the pipeline but will be available via most stores, too. If you’re not sure if you want to buy one, the publisher has some samples on the website.
* The headline means “Book! Book! I’m going crazy!” in Austrian. It’s a reference to a commentary to the soccer game Germany-vs-Austria Córdoba 1978 (just replace Book with Tor, which means Goal) which is even famous outside of the soccer fanbase. In fact I don’t like soccer at all but I thought it would be a nice headline.
For your reference:
Icinga Classic UI users brace yourselves: clickable custom filters are on their way. If you really prefer to filter via URL, you are welcome to continue to do so, but the less swift of hand can look forward to:
Simply click on “Set Filters” and a pop up window with a range of options will appear. Click away and apply, to have your hosts or services filtered as you please.
From seeing which services are currently in WARNING or UNHANDLED states, to seeing which of them have notifications enabled or are flapping, the new filter ought to make Classic UI just that bit more intuitive and enjoyable to use.
Cheers to stku for the (longstanding) feature request, and my girlfriend for bearing with me while I cursed away at my computer upon discovering an annoying mistake in the source code. The curious will find my rants in the code on git.
We hope you look forward to Icinga 1.10 coming in 50 days as much as we do.
As you may have noticed, the web developers already released a bugfixed 1.5.1 Icinga Web version (and 1.5.2 is to be announced soon). Now it’s time to fix some Core, Classic UI and IDOUtils related issues – so the core team is releasing 1.5.1 too 🙂 Changelog

As usual, please download from sourceforge and report any bugs or features requests to our dev tracker and/or support channels.
Due to the recent fixes in 1.4.1 the XSS vulnerability caused the command expander in config.cgi not to work as expected. Alongside this bug, there were various other things to resolve while working on the 1.5 dev branches. All important fixes have been backported into 1.4 tree and can now be found in a revamped 1.4.2 release on Core, Classic UI and IDOUtils. Download 1.4.2 now or wait for your distribution to push updated packages 🙂 Special note: 1.4.2 does not require IDOUtils DB upgrading. Changelog
