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" myemail@mywork.sch.uk

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??

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.
