Hi Marc,

Thanks for the update. Actually all the macros seem to be quoted in
the command definitions. Check the below mentioned command
definitions. Nagios was supposed to use them for the service I
mentioned.

define command{        command_name    notify-by-email
        command_line    /usr/bin/printf "%b" "***** Nagios
*****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService:
$SERVICEDESC$\nHost: $HOSTALIAS$\nURL:
https://some-url/hosts/show/$HOSTADDRESS$\nState:
$SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional
Info:\n\n$SERVICEOUTPUT$" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$
alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
        }

# 'notify-by-pager' command definition
define command{
        command_name    notify-by-pager
  command_line  /usr/bin/printf "%b" "$NOTIFICATIONTYPE$:
$HOSTALIAS$/$SERVICEDESC$ is
$SERVICESTATE$\n$SHORTDATETIME$\n$SERVICEOUTPUT$" | /usr/bin/mail -s
"$NOTIFICATI
ONTYPE$: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" $CONTACTPAGER$
        }

But one more quick question: If the issue were related to "not quoting
the macros in command definition", Nagios should have logged something
regarding the "SERVICE NOTIFICATION" right (though whether we received
the notification or not). Correct me if I am wrong. Looking at the
logs, I am guessing that due to some reason, Nagios didn't initiate a
notification at all.

Thanks,
Satish
