Nagios Support Forum

Hi,

i'm new in nagios and i'd like to know whether the source code is totally free. can i download it and modify it for my personnal utilisation?
this seems to be possible with Nagios Core doesn't it?

is there a correlation engine in Nagios?

best regards
C

Yes, Nagios Core is GPL: https://github.com/NagiosEnterprises/na ... er/LICENSE

Many plugins are also open source, but you'll have to look at each plugin individually to see the license. For example, this one is also GPL: https://github.com/nagios-plugins/nagio ... heck_apt.c

You are going to have to be a little more specific. Are you talking about root cause analysis? If so, there's nothing built in, but there are a ton of add-ons at https://exchange.nagios.org/

i mean that i don't want necessarly to see all alerts if any are dependant from others.
exemple:
i have a LAN with 25 computers hen the router downs, i don't want to see all hosts down
i want to be able to launch scripts or others commands on receiving some kind of alert

When you have different questions like this, you should generally post them as separate threads.

That said, I think these a pretty simple:
router down: https://assets.nagios.com/downloads/nag ... ncies.html
scripts: https://assets.nagios.com/downloads/nag ... dlers.html

If you have specific questions about both of those, please post one of them as a new thread.
