Nagios 2.5
First let me start off by saying Nagios is not for the timid. But once configured correctly is very powerful monitor tool, both for the small company and the large enterprise as well.
Nagios is not all that easy to configure. However, I must say that the manual in PDF format has come a long way to try and document such a very versatile program.
Installation will take time be patient. There are several steps in which to do so. If your installing nagios on a REDHAT linux server you need to make sure that your pre-requistes are installed first. I know that the manual does not outline these very well. In Fedora Core 6 you need to install the following rpm’s first so that all of the components are compiled correctly. I would recommend installing nagios from the tar.gz and compiling the rpm version which I know probably has taken some very hard hours of work just does not install everything you need.
Install rpm from yum install
gd
openssl
php-gd
php-devel
These are necessary components that you are going to need before you start compiling nagios from source. The directions in the manual from that will work just follow them step by step closely and all should come together nicely.
I welcome any additional comments or experiences you may have had during the installation process. Post your questions as well. I will do what I can you help
