As an intern I am tasked with migrating a Nagios server from a defective Ubuntu 14.04 VM to a new one, presumably a Debian 9.
I chose icinga since I had no previous knowledge of monitoring, and since Icinga has debian repositories.
My boss validated the idea, and I clumsied around long enough to have a working (though minimal) Icinga2 & IcingaWeb2 VM.
Today my boss' boss came to visit and said that at his level, they use Open Monitoring Distribution and that it seems powerful.
Asking further on the Net, I was proposed too Eyes of Network (a full distribution based on CentOS - I'm not used to RedHat or rpm but I'm not sectarian).
So, any advice on the pros and cons of each solution?
