New to Nagios - few questions?

[ericmachine]

Hi everyone,

I am new to Nagios. I have couple of questions.

a) I saw the sticky post on how to install - http://www.unixmen.com/install-nagios-i ... an-squeez/

well, can i used that to install on ubuntu 10.04 LTS 64 bits server?

b) Is there any updated tutorial which it shows how to install the web front end too? Any recommended a good and nice web interface for nagios?

c) Is there any nagios core distro that comes with ubuntu (iso format), so it is easier to install?

d) i have one question which like to confirm my understanding.

Now I have 1 virtualised server with 4 virtual machines as below:-

** all these virtual machines are installed with ubuntu 10.04 LTS 64 bits server and has individual IP itself which can be access via IP or subdomain e.g. erp.mydomain.com.

i. erp server
ii. doc server
iii. portal server
iv. website server

each virtual machine will have database, web server, etc.

I need to monitor my virtual machines performance, uptime, website (no hacking), etc.

I believe I need to create a new virtual machine with Nagios Core. But how can my new virtual machine able to pick up information from the existing virtual machines which the virtual machine has no access?

Any help? thanks in advance

Probably, give it a try and let us know ; )
Just know that a package-installed version of nagios will have different file locations than a source install.

b) Is there any updated tutorial which it shows how to install the web front end too? Any recommended a good and nice web interface for nagios?

Most of the front-ends listed have fairly straight-forward setups.

I always recommend V-Shell, but only because I wrote it ; ) Most of the themes are pretty nice too, and Exfoliation ships with the latest 3.3.1 source install.

For the VM's, I would just use the traditional nrpe-agent method. Nagios sends a request to the agent on the other machine, the agent runs the check and sends the results back to Nagios:
