quick upgrade questions

[sheetzdw]

I am planning to upgrade Nagios from Nagios Core Version 3.3.1 to the latest version and migrate to a physical box at the same time

Where can I see a list of ALL Nagios plugins currently installed on my server?
How can I move JUST the alerts / hosts configuration to the new version, is this possible?

I was hoping to install new versions of Nagios and Nconf ( and any other plug ins) on a new clean install of Ubuntu server then hoping I just needed to copy some config files


IS there a good document or forum thread on this issue?

This should cover backing up and restoring:

http://assets.nagios.com/downloads/nagi ... ing_XI.pdf

Plugins are located in:

Code: Select all

 /usr/local/nagios/libexec/

Keep in mind if you change IP addresses to make sure to also change it in the web interface at Admin > System Settings.

thanks thats a good start I will keep searching

I need to be fully aware of what I am getting into

dont want to blow up anything

[slansing]

Haha, as long as your backup does not fail, and you don't go removing the entire XI server before the other one is up and processing fine then you should be good! We're here for you to make sure everything goes as smooth as possible.

cool, I am trying to convince them to buy support and all useful options so we can get this moving quick as possible
I have no real view into network traffic and alerts are a full time job because not all are configured correct and I am new to Nagios
the sooner I can get this working right and mastered the better... hopefully before you get tired of my posts

Ahh, I just realized I posted my above responses thinking this was regarding Nagios XI not core, Core should be simpler to move in most cases.

[sheetzdw]

I was wondering about that

glad to hear it is easier

do I have to move any Apache components or MYSQL db's also? I would assume so

[sreinhardt]

Yep, Apache would likely come with a new nagios installation, unless you have unique additions. Mysql will definitely need to be duplicated.

[sheetzdw]

so is it safe to assume MYSQL holds all settings like hosts , services ,etc?

Can I edit that directly?

[slansing]

It will generally hold configuration information if you are using it, if you have just set up a standard nagios core installation and not added anything like NagiosQL you are probably not using Mysql. You are still manually adding and changing configurations from their flat files correct?
