Nagios -> Email Arghhhh!

[ICTNUT]

Hi All,

 

I have done a clean vanilla LAMP install (Ubuntu 7.10 Server) and then install Nagios 3.03 with the plugins.

 

Now all is working fine aprt from emails are not getting sent.

 

This is what I have done;

 

1. Change the email address in contacts.cfg to mine
   
2. install mailx as per nagios instructions
   
3. changed email config in commands.cfg to show /usr/bin/mail and not /bin/mail
   

 

Now when I bring a host down I get no email, I have always used nagios without email notification, more of a visual thing but Iwould like to get this sorted now.

 

Any ideas of what I need to look for??

Forgetting nagios for a second, can you send mail from the terminal using the mail command?

[ICTNUT]

hmm good point have not tried that, don't have remote server access to this server so i'lltryit in the morning....

 

To be continued

Ok from the command line i did the following:

 

mail -s "this is a test" [email protected]

 

then it just sits there doing nothing until I escape out, so it would look like email is not setup correctly on the box.

 

Any ideas anyone??

[kmount]

It will sit there as that's expected behaviour for the command you entered.

 

If you put a single period . and press enter and enter again it should exit cleanly.

OK did it agin and got:

 

.

Cc:

Null message body; hope that's ok

 

this then returned me back to the command prompt and as yet no email

Unsure about ubuntu but look in /var/log/mail.log for your email to see what it says.

Install the 'ssmtp' package and configure /etc/ssmtp/ssmtp.conf to suit your network enviroment.

[kmount]

It suggests you don't have an MTA.

 

Do the nagios instructions tell you to use apt-get/aptitude or install from a deb?

[ICTNUT]

Install the 'ssmtp' package and configure /etc/ssmtp/ssmtp.conf to suit your network enviroment.

 

Spot on Geoff: We now have mail from the command line

 

Will now go and trip up nagios to see if mail comes from there also, I may return......

[kmount]

Woo

[ICTNUT]

We have email from nagios YEY!

 

Many thanks guys.

[kmount]

Now all we need is for Nagios to make coffee and cookies.

EDIT: Came back and posted this far too late.

Are email notifications enabled by default? Is there any configuration you have to do?

 

I have followed the instructions in this thread and I am able to send emails using the command line but Nagios is not sending any emails when services go critical.
