Imagine you have one more special thing to monitor. While our Icinga 2 can observe infrastructure of almost any size, it still needs a plugin for each kind of check. Unfortunately not every command...
Turns any command into a plugin: check_rungrep

Monitoring domains and DNSSEC properly
First of all, if you own a domain, the following text is for you. In production you obviously want to reduce outages. And an outage of a DNS domain as such takes down all services under that domain, no matter whether your LAMP components are all up and running. At...
Icinga for Windows without an Icinga 2 agent
I've already dropped a hint at this topic in a previous post of mine which reflected the history of Icinga on Windows: Icinga 2.14 will be able to directly speak to the PowerShell daemon REST API without even fork(2) or exec(3) for a subprocess (...). In fact this...

Critical hotfix releases: Icinga 2.14.1 and 2.13.9
Imagine you've installed Icinga 2.0.0 on 2014-06-06, the day it was released. You've tested its features, over the time we've added more of them and by now your test cluster went in production. An Icinga cluster operates on TLS which involves a root CA, typically...

In our community forum Michael already outlined the possibility to operate Icinga 2 with an external certification authority, not the one Icinga 2 generates by itself. Thomas, one of our NETWAYS colleagues, reported his experience in that field: in short, it's easy to...

The future of Icinga + Windows: Schrödinger’s agent?
I remember as if it was yesterday. I participated at the OSMC 2014 and watched Bernd's talk "Current state of Icinga". In the live demo Bernd has showed some of the new things we've built. One of them he introduced somewhat hesitantly IMHO: Now there is... not only...
Security releases: Icinga 2.13.7 and 2.12.10
Recently the OpenSSL project released OpenSSL v1.1.1t and advised its users to upgrade due to several CVEs that release has fixed. We're not certified security experts, but we know that a redundant update is better than a missing update. While on Linux the OpenSSL...

Resolving Git merge conflicts – easily and accurately
Nobody likes resolving merge/rebase/cherry-pick conflicts. I also don't, but I've found a scheme how to reduce the built-in headache. In this post I'm going to share my findings as well as practical examples. Warming up First let's brush up on merge conflicts with...
