How to connect to the Icinga 2 API via the Icinga Console

Today I will show you a couple of small functions you can use with the Icinga Console. Using the Icinga Console can help with scripting in general and provides a quick and easy-to-use way of extracting information from your Icinga environment. We will take a look at extracting information belonging to the service objects in Icinga. Obviously, you can pinpoint different objects, like host objects, with which you can work via the Icinga 2 API and Console.

Creating dashboards based on custom filters

In this blogpost, I explain how to create dashlets using custom filters. This way you can create dashlets of your own which you find is necessary. Having dashboards in fact improves monitoring. Dashlets are the different sections under the given dashboard, which are the snapshots of some monitoring views and are defined by a name. Requirements: Icinga 2 and Icinga Web 2 installed.

Icinga 2 Config Sync: DIY Edition

Two weeks ago, Icinga 2 Config Sync: Behind the Scenes explained how the config sync in Icinga 2 works and how you can look behind the scenes.

Icinga 2 Config Language (DSL): Advanced Apply Rules

As many users of Icinga don’t know what the DSL has to offer, I’m going to show you how to use custom variables and apply for rules to make your life easier when writing configuration for your Icinga environment. In this example we will use custom variables on a host to configure a dynamic set of services to monitor multiple web services behind a reverse proxy. On the host we define a custom dictionary called http_vhosts and assign our virtual hosts to it.

Icinga 2 Config Sync: Behind the Scenes

Today’s blog post dives into the internals of Icinga 2 and will give you an overview how the config synchronization works internally. We will take a small cluster as an example and follow the configuration files through the synchronization mechanism. We assume some familiarity with distributed Icinga 2 setups as this post will not go into details on how to set up an Icinga 2 cluster.

One aspect that got attention is the display of downtimes, using their time based nature and putting the resulting data into context and visualizing it. Here are some of the details.
