General questions about nagios

[benilzha3]

Hello everyone,

I've recently been promoted to our nagios admin! (yay for promotions!!! sarcasm)

I've done some basic searching but I thought this would be a good place to get clarification on a few things.

Environment consists of centos 6 and centos 7 systems.



A lot of guides give examples of installing nagios core via source code + compiling. I see there is a nagios version 4.4.3 rpm package available via epel repo. is there any reason I would want to compile it instead of just using the rpm?

should i be using nrpe or xinetd?

should the plugins be installed on any/all targets (system i'm monitoring) or only the source (nagios server)

if I wanted to acknowledge an alert via email/sms, is there a plugin I need or is this an "out of the box" feature?

I personally use xinetd
