Icinga 2 DSL Feature: Namespaces coming in v2.10

Under the hood, Icinga 2 uses many constants and reserved keywords, e.g. “Critical” or “Zone” which are respected by the config parser and compiler. This sometimes leads to errors when users accidentally override such things, or re-define their own global constants. v2.10 introduces namespaces for this purpose, and ensures that such accidents won’t happen anymore.

 

What exactly is a namespace?

Think of a defined “room” for variables, functions, etc. which can be defined similar to constants. They are isolated from other namespaces and must be loaded by the user/developer. Namespaces need a defined name – we prefer to use a capitalized string, e.g. “MyNamespace”. This helps to immediately qualify this as customization when reading the configuration.

Icinga 2 v2.10 uses namespaces which are registered and loaded by default. In order to test this, open the debug console on a test VM which has the snapshot packages installed. Fetch the keys in global namespace “globals” first.

Monthly Snap August: Icinga Camp Tel Aviv, OSMC Schedule, Icinga 2 Book & Releases

Our first Icinga Camp Tel Aviv happens on December 17th, 2018, the fourth edition in Berlin takes place on March 14th, 2019 again :)

The first Icinga meetup in Salzburg, Austria happens on Oct 12th, 2018 – join for more #icingalove. The Berlin meetup was a great success, Carsten and Lennart joined there too. Watch their meetup group for future dates.

The OSMC 2018 schedule is online, with so many interesting talks in two days on three tracks. The hackathon on the last day is also back for more #icingalove.

Watch out for future Icinga trainings by our partners. There’s a new workshop available by NETWAYS which practices automated setups with Puppet and Icinga.

This month brought many releasesIcinga Web 2.6.1 as bugfix release, Graphite module 1.1 and Director 1.5. Icinga joined the OpenAPM initiative in August, you can learn more about it at OSMC later this year. We’ve also learned that Icinga is now an official input for InfluxDB’s Telegraf.

Carsten released v1.3.0 of the Grafana module for Icinga Web 2. Claudio shared insights into pinning checks in HA enabled cluster zones. Our partner NETWAYS has uploaded their webinar on building an Icinga 2 environment. Bernd updated his blog post series on monitoring tools which includes Icinga (obviously ^_^).

When the Icinga 2 book v2.0 got released, you are doing crazy things …. you’ll pause your vacation and drive 140 km … or you’ll wait and take it with you … sit at home and wait like xmas … compare the size, it is huge … feel motivated in a new week … and just love it.

Nagstamon turned 10 this month, cheerio 🎂 Gunnar provided a patch for Icinga 2 which adds references, crazy shit. The monitoring plugins team and community members are working on check_curl replacing check_http at some point. Why would time be wrong, monitored with Icinga? ;)

Thank you Sascha for the nice view with the Icinga 2 book!

Icinga on OpenAPM

Building your monitoring landscape can be a hard task. The main reason for this is the sheer amount of available solutions. Even though, each of them has their own reason for existence. One challenge during the discovery phase is to find out if the tools you selected can work together. If they have integrations for each other or if they can use the same storage backend. OpenAPM aims to help you find out which parts can work together and how you may use them in combination. Further, it gives you some inspiration on what you can change to get your perfect monitoring stack. read more…

Icinga joins HashiCorp Technology Partner Program

One of the biggest advantages of Icinga is its capability to interact with other tools. Integrations of Icinga cover notification mechanisms, visualisations or automatic deployment. Especially our REST API allows users to easily connect with Icinga, be it for read access or the creation of new objects.The possibility to automate allows Icinga users to monitor highly dynamical infrastructure in private and public clouds. read more…
