Sentinel: Icinga / Server & Services Monitoring

introduction

note: base directory will be /etc/icinga/ unless stated otherwise

Access

Our Icinga installation is named 'Sentinel' which means "a soldier or guard whose job is to stand and keep watch", you can find Sentinel here and login with your Keberos username and password.

Kerberized SSH connections

We use AutoSSH to allow Icinga to connect to other nodes to execute commands and get services information back.

Internally, we can use Kerberos to jump from one host to another our Icinga installation requires HTTP Kerberos auth (via https) but we've also set up AutoSSH which allows our Icinga instance to connect to other nodes passwordless & ssh key-less to fetch information.

more information, show how we've setup the connections, etc
