Icinga 2 Agents

Working with Icinga 2 Agents can be quite tricky, as each Agent needs its own Endpoint and Zone definition, correct parent, peering host and log settings. There may always be reasons for a completely custom-made configuration. However, I’d strongly suggest using the Director- assisted variant. It will save you a lot of headaches.

Note

In order to use all the functionalities of NetEye 4, use our Icinga2 Packages userguide to get icinga2 packages for different OS/distributions via the NetEye repositories for Icinga2 agent installation.

Preparation

Agent settings are not available for modification directly on a host object. This requires you to create an “Icinga Agent” template. You could name it exactly like that; it’s important to use meaningful names for your templates.

Create an Agent template

As long as you’re not using Satellite nodes, a single Agent zone is all you need. Otherwise, you should create one Agent template per satellite zone. If you want to move an Agent to a specific zone, just assign it the correct template and you’re all done.

Usage

Well, create a host, choose an Agent template, that’s it:

Create an Agent-based host

Once you import the “Icinga Agent” template, you’ll see a new “Agent” tab. It tries to assist you with the initial Agent setup by showing a sample config:

The preview shows that the Icinga Director would deploy multiple objects for your newly created host:

Create Agent-based services

Similar game for services that should run on your Agents. First, create a template with a meaningful name. Then, define that Services inheriting from this template should run on your Agents.

Please do not set a cluster zone, as this would rarely be necessary. Agent-based services will always be deployed to their Agent’s zone by default. All you need to do now for services that should be executed on your Agents is importing that template:

Config preview shows that everything works as expected:
