Monitoring system Icinga 2

The Monitoring system Icinga 2 course is suitable for infrastructure and system administrators who are considering to deploy the system to supervise the applications. It is suitable for administrators who want to migrate from Nagios or an older version of Icinga 1.x to the new version. The course is practically focused. After the introduction to the basic concepts, we try to add our own systems and services to the surveillance together. We take advantage of the new features of Icinga (templates, etc.) so we could keep the configuration as small and arranged as possible. The second day we install and configure Icinga to an empty operation system, and join with two machines. Finally, we talk about other available modules, features and add-on tools that can extend Icinga. We also look into the Icinga cluster. By the end of the training, participants will be able to deploy and configure Icinga, and be able to consider whether it is suitable for deployment in a given scenario.
