Hello everybody. I'm trying to configure SMS alerting for Nagios Core and I've almost succeeded, however, I can't for my life figure out how to start a new line when sending a text message via smssend. Here is an example of a command I'm using to send an SMS alert, how can I eg. divide "Host" and "State" on different lines?

define command { command_name notify-host-by-sms command_line /usr/bin/printf "%b" "Notification Type: $NOTIFICATIONTYPE$ Host: $HOSTNAME$ State: $HOSTSTATE$ Address: $HOSTADDRESS$ Info: $HOSTOUTPUT$ Date/Time: $LONGDATETIME$ Additional Info: $SERVICEOUTPUT$ " | smssend $CONTACTPAGER$ }

The script sendsms supports single line only. I assume that smssend in CentOS is the same.

You could create a message file directly. There are several possibilities for that. I have used this:

define command{ command_name notify-service-by-sms command_line /bin/bash -c 'F1=`mktemp /tmp/nagios_XXXXXX` && \ /usr/bin/printf "%b" "To: $CONTACTPAGER$\n\n$LONGDATETIME$\n** $NOTIFICATIONTYPE$ $HOSTALIAS$ Service Alert: $SERVICEDESC$ is $SERVICESTATE$ **" > $F1 && \ F2=`mktemp /var/spool/sms/outgoing/send_XXXXXX` && \ rm $F2 && \ mv $F1 $F2' }

\n starts a new line, as you likely knew, but it did not work with smssend.
