[SOLVED] Re: nagios not sending mail (nagios -> postfix connection problem?)

[Jim Nachlin]

Patrick,

You were correct!

I have overwritten my original command, but the essence of the
solution was to run the command_line of the notify-by-email command.
This immediately showed me that there was no "/usr/bin/mail" on my
server.

So here is the command that works:

define command{
        command_name    notify-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios
*****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost:
$HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo:
$HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "**
$NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **"
$CONTACTEMAIL$
        }


If anyone reading this is having a problem with Nagios not sending
mail, and there's nothing wrong with your MTA or email account, then
check that the command you are piping to actually works!

Simplifying the above command_line:

$ echo "this is the body of a test message"  | /bin/mail -s "this is a
subject" your_email at example.com

All the data continuously generated in your IT infrastructure contains a
definitive record of customers, application performance, security
threats, fraudulent activity and more. Splunk takes this data and makes
sense of it. Business sense. IT sense. Common sense.
