Need some Information/Guidance regarding Nagios installation

[Siddharth Hegde]

Hi,

I have to install nagios on server which is behind layer of DMZ and private network and also have couple of modules already installed and running in that particular server, i.e, MongoDB and RabbitMQ.

Is it a good practice?

And also server won't be exposed to public, how will email notifications work as couple of contacts are not in that private network?

Thanks in advance for any advice and suggestions

Personally I always recommend installing Nagios on its own server, but it should play nice with other modules.

And also server won't be exposed to public, how will email notifications work as couple of contacts are not in that private network?

This would be up to you. My guess is you would have to configure the server to send mail to a mailserver on your network, and hopefully that mail server knows how to reach out to the public.

Hi,

I tried installing Nagios, but I'm getting the following error

Code: Select all

apt-get install php libapache2-mod-php php-mcrypt php-mysql

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgd-dev : Depends: libfontconfig-dev
E: Unable to correct problems, you have held broken packages.

What does this do? Is it necessary for me to install this? I don't want web access, just email notifications will do

Code: Select all

sudo apt-get install build-essential libgd2-xpm-dev openssl libssl-dev unzip

And I'm not allowed to create a new server. I have to somehow install Nagios in this one

Is there another way?

This server has a bunch of broken packages. This will need to be resolved before you can even start the actual nagios installations.

This is just installing a few of the dependent packages. Just like the other apt-get commands.
