Hello all,

I have successfully installed nagios on my fedora box and i wish to monitor the following services.

-> Networking performance
-> Disk usage and performance
-> HDD and system temperature

Can any one give me some guidance regarding that?After setting up the nagios how should i enable monitoring of services?

The simple answer is that when you installed Nagios you also installed its documentation and maybe even some rudimentary examples in /etc/nagios. Reading the documentation and examples will provide you with an idea on how to set up checks. Note this is not a "RTF(ine)M" answer but a known stumbling block for most new Nagios users as they won't do that (see it as part of your Nagios initiation) or expect a point-and-click experience (that is not what Nagios is about). Searching LQ for Nagios-related threads will yield results but you have to be willing to invest time. Also see the "Similar Threads" at the bottom of your thread as it mentions a frontend for Nagios if you are absolutely allergic to the commandline. We wouldn't want you to convulse and collapse ;-p

Since it might not be easy if you're new to Nagios I suggest you pick one service or check (say diskspace), read the docs, whip up an example config, try to run it, and post it here (preferably in BB code tags for readability) and ask for corrections.

Thanks unspawn,i'm pretty new ( well totally a noob) to nagios and to linux as well.The only monitoring tool that i installed successfully was rrd with ntop graphs ,well wanted to try nagios now.It seems pretty tough me and your true about the fact that it requires considerable amount of time.Well ill try looking at those examples and start with basic services like ,monitoring ping and disk space e.t.c Will post it here if i get something wrong,thanks again for your guidance. :-)
