that's it if your mail program is /usr/bin/mail

2006/1/27, Nicola Agnelli <nicola.agnelli at spiderwall.com>:

Thank you very mach,

so for "notify-by-email" I sould add

 

|  /usr/bin/mail -s "Service $HOSTALIAS$ alert for $SERVICEDESC$!"
$CONTACTEMAIL$

 

Right ?

 

Tnx

You should use the variables to get more info :
# 'host-notify-by-email' command definition
define command{
        command_name    host-notify-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios
*****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState:
$HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $OUTPUT$\n\nDate/Time:
$DATETIME$\n" | /usr/bin/mail -s "Host $HOSTSTATE$ alert for $HOSTNAME$!"
$CONTACTEMAIL$
        }

Thank you for answer,
so the correct command should be: 

define command{
>         command_name    notify-by-email
>         command_line    /usr/bin/printf "%b" "***** Nagios
> *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService:
> $SERVICEDESC$\nHost: $HOSTALIAS$\nAdd$ | mail -s Notification
>         }

And

define command{
>         command_name    host-notify-by-email
>         command_line    /usr/bin/printf "%b" "***** Nagios 
> *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState:
> $HOSTSTATE$\nAddress: $$ | mail -s Notification
>         }


?

Sorry for my questions but I'm new to nagios ..

The first step could be to modify your command_line to actually send a
message. Usually, you use printf to create and format the output AND
THEN pipe that output to your mail program.

Like 'printf "somethning" | mail -s Notification ...
