How to send Mail Notification

[Dragon]

Hi, i'm a new on this forum
I request a configuring Nagios to send a mail these problems CRITICAL and WARNING.
Example:
On the web i read the results of one or multiple commands.
One command resulted a 3 Critical, 5 warning and 10 OK.
The information of the message results and detailed problems should be sent via mail me@test.com
Thanks

Hello,

1. Configure your contacts.cfg file in nagios /etc/objects/ directory
2. Configure your notification options in templates.cfg or host/service definition to set when nagios should send information
3. Configure your notification message in commands.cfg file
3. Install MTA (i.e Postfix) and configure it to send e-mails

that's it.

Thank HanzKlotz
I have configured three points, but not the four.
Where can I download the file MTA?
Thank's very much

Where can I download the file MTA?

MTA is a mail transport agent. Look at http://en.wikipedia.org/wiki/Mail_transfer_agent
Try to understand before you install it.

I hope to run this application
Thank HanzKlotz

MTA is a category of programs, not the name of anything specific. Examples of specific tools you could use for this purpose include: postfix, sendmail, exim, and msmtp. Configuring these is outside the scope of this forum, but I think most server Linux distributions come with one preconfigured. So if you correctly did steps 1-3 that HanzKlotz mentioned, you should probably be getting email alerts already.

Getting so little information from you, though, makes it hard to know what to suggest to you. Since you seem new to Nagios I'd recommend finding a good book to guide you through setting it up, like Learning Nagios 3.0.

Riddler, what is the issue you are having? Can you clarify this for us?

[eltrasimaco]

Is the daemon running? did the telnet thing work?
What does /var/log/maillog say?
And /var/log/messages?
