Re: Nagios HTML mail

Post by ericosman »

I'm "logged in" as nagios
bash-4.1$ nagios-html-email service http://nagios.example.com | mailx -t
env NAGIOS_CONTACTEMAIL or `-a <address>` must be supplied!

Usage: nagios-html-email [options] <service|host> [arg1] [arg2] ...

This command is meant to be run from nagios when a service or host
experiences problems. The output will be suitable for passing to
a mail program that takes raw email data like `mailx -t`

Options
-a, --address <email> the email address to send mail to, defaults to env NAGIOS_CONTACTEMAIL
-h, --help print this message and exit
-s, --subject <subject> the email subject to use, defaults to _subject for the host/service, or default nagios subject
-t, --template-dir <dir> dir to find ejs template files, defaults to builtin templates
-u, --updates check for available updates on npm
-v, --version print the version number and exit
No message, no subject; hope that's ok
No recipients specified

To correct rhassing a wee bit, I would highly suggest against setting nagios user to have a valid shell by default. "su nagios -s /bin/bash" should always be used instead to specify the shell for this user session. Regardless, it looks like the script is giving you errors not because of who you are running as, but because you are not providing a sending address, recipient, subject, or message.

Try something like, this is only going to output the message to screen, but let's make sure its formatted correctly first before trying to send it off:

Code: Select all

nagios-html-email-service -a youraddress@yourdomain.com -s "this is a test" mailserver.yourdomain.com

What is the output of:

Code: Select all

nagios-html-email service http://nagios.wetron.intra
If it is empty, then there is an issue with the script or the service passed to it.
It it outputs data, then the issues is with mailx or the pipe.

We actually do not want to send an email, so sans the | mailx -t would be ideal. We purely want to make sure that the output from your nagios-html-email is correctly formatting output prior to piping to mailx. It sounds like some or most of it is right, but clearly parts of it are not.

Methinks your script no-worky.
By the way, it has not been updated in three years

Were you running it as user nagios?
Can you post the command definitions you are using?
