$SERVICEOUTPUT$ empty

#1

I am using version 2.0 last modified 2-7-2006.

The notification by e-mail doesn’t have the $SERVICEOUTPUT$. Here is my misccommands.cf entry:

‘notify-by-email’ command definition

define command{
command_name notify-by-email
command_line /usr/bin/printf “%b” “***** Nagios ***\n\nNotificat
ion Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAdd
ress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdd
itional Info:\n\n$SERVICEOUTPUT$" | /usr/bin/mail -s " $NOTIFICATIONTYPE$ al
ert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **” $CONTACTEMAIL$
}

(The above is one continuous line.)

How do I troubleshoot this? I know the service commands are producing output because I see it on the web pages.

Thanks for any direction on how to solve this.

some interesting information…

I changed the command to say:
define command{
command_name test-notify-by-email
command_line /usr/bin/printf “%b” “***** TEST *****\n\nAdditional
Info: $SERVICESTATE$\n\n$SERVICEOUTPUT$ \n\nafter: $SERVICESTATE$” | /usr/bi
n/mail -s " $SERVICESTATE$ " $CONTACTEMAIL$

}

and now the SERVICEOUTPUT variable is shown, but the after part does not…what would be causing that?

SOLVED!

It looks like you just need to ensure that the varialbe $SERVICEOUTPUT$ has a space, newline, or other text. For example:

BAD FORMAT

define command{
command_name test-notify-by-email
command_line /usr/bin/printf “%b” “***** TEST *****\n\nAdditional
Info: $SERVICESTATE$\n\n$SERVICEOUTPUT$” | /usr/bin/mail -s " $SERVICESTATE$ "
$CONTACTEMAIL$

}

GOOD FORMAT

define command{
command_name test-notify-by-email
command_line /usr/bin/printf “%b” “***** TEST *****\n\nAdditional
Info: $SERVICESTATE$\n\n$SERVICEOUTPUT$\n” | /usr/bin/mail -s " $SERVICESTATE$ "
$CONTACTEMAIL$

}

Notice the newline after $SERVICEOUTPUT$.

Maybe that’s a bug?

Also, it means the misccommands.cfg-sample notify-by-email is broken.

Thanks for listening! :slight_smile:

It’s not a bug, it’s how you send mail when using the “mail” command.
If doing it by hand, you send mail with a CTRL-D at the end of a “NEW LINE”. So, that’s why you need the \n

Thanks. That makes sense.

Interestingly, adding a space after $SERVICEOUTPUT$ also worked even though there weren’t any new lines.

I see, I was wondering about that, since my command only had a space.
