1   Introduction¶

Puppet deployment consisting on monitoring system based on a master-client design, in which all puppet clients will automatically enroll to the icinga master, also being reflect in the Web Interface through IcingaWeb2, handled by Icinga Director and deploying graphs through PNP.

The taken approach allow us to have multiple master instances, and that every node response to their own master. For future developments, the idea is to join the masters into a replicate configuration to visualize all instances.

2   Requirements¶

In order to deploy Icinga2 and IcingaWeb2, there are several dependancies that have to be taken care off. The built code includes those references and is in a “ready to deploy” status

3   Code References¶

The configured code can be found in both the public and private repo:

• Icinga Master https://github.com/lsst-it/lsst-itconf/blob/master/site/profile/manifests/core/icinga_master.pp
• Icinga Agent https://github.com/lsst-it/lsst-itconf/blob/master/site/profile/manifests/core/icinga_agent.pp

4   Services, Hosts and Templates¶

There are 4 things (or objects) to take in consideration: Host templates, Service templates, Hosts and Services. Host Templates are responsable of providing the final host object an inheritad default configuration, as well as a default configuration. Service templates are the ones that have the “check_command” on them, which means, is the one that defines which operation is going to be perform in the remote host (without defining yet the host). Services per se, links or vinculates a Host Template with a Service Template, so all hosts that use the defined Host Template, will automatically inherit the previously linked Service Template. Finally, when you define a Host, you simply use the defined Host Template, and the host will add itself with the Service Template (check_command, monitoring operation that will be perform) into the icinga master.
