Icinga 2 can generate its own alerts when a host or service has reached a certain state (hosts: UP, DOWN, or UNREACHABLE, services: OK, WARNING, CRITICAL, or UNKNOWN). With the right configuration the monitoring software sends out emails, text or instant messages, etc. to users or user groups. (Check out our documentation to learn more about Notification objects.) As soon as you want to organise notifications for more than a few people or several teams with different on-call duties, things can become a bit uncomfortable in Icinga 2. (more…)
Most of us use Icinga 2 to monitor network services, host resources or server components – but wait, there is more! Why not ask Icinga 2 to watch items in your favourite online shop and send out notifications as soon as the price has dropped below a certain amount? Antony Stone has written a slightly unusual check to track the price of Amazon items with Icinga 2. (more…)
Like many other Open Source projects, the Icinga team uses GitHub as its hosting service. Over 25 different repositories contain our monitoring software Icinga 2, the web interface Icinga Web 2, Docker containers and Vagrant boxes, various modules, etc. Some of the repositories offer simple installation instructions and configuration examples (README.md), others contain a subdirectory called doc with more detailed instructions and several files.
To create a handbook for offline viewing, you don’t need to copy & paste the content of all the files into your favourite text editor or word processor and start from scratch. All of the guides are written in Markdown, a lightweight markup language with plain text formatting syntax, and it is quite easy to convert them to other formats like plain or rich text, HTML, HTML5, Wiki markup (MediaWiki), LaTeX, PDF, ODT, or EPUB. All you need is a little commandline tool called Pandoc .
