Nagios is installed - Just three things we need it to do



I installed Nagios successfully on a Linux server.
My boss wants Nagios to do just three things.
1.) Monitor disk free space on the local server.
2:) Monitor any disk drive failures on the local server.
3.) Send a warning/alert email to our I.T. Support if anything goes wrong.

How I configure Nagios to do this if it can?

Thank you


It can do those things, and a good place to start would be the documentation that comes with nagios, which is linked to in the web gui. There is even a quick start guide. After you read that, come back with more specific questions, if needed.
