i have just installed Nagious on gentoo using emerge command.
but i want to configure that so that i can monitor different services. as i am new to nagios so can any one help me by providing me information how to configure it.
Nagios, like linux, is a very powerful program. The only problem with 'powerful' programs, is they take a lot of dedication to setup the way you want them, but once they are, you don't have to touch it for a very long time.
Even Nagios says in it's documentation the following statement to beginners:
"Relax - its going to take some time. Don't expect to be able to compile Nagios and start it up right off the bat. Its not that easy. In fact, its pretty difficult. If you don't want to spend time learning how things work and getting things running smoothly, don't bother using this software. Instead, pay someone to monitor your network for you or hire someone to install Nagios for you. :-)"
