I have configured sms with gammu-smsd. gammu-smsd configuration has been given below:

#vi /etc/gammu-smsdrc

 # Configuration file for Gammu SMS Daemon

 # Gammu library configuration, see gammurc(5)
[gammu]
 # Please configure this!
port = /dev/ttyACM0
connection = bluephonet
 # Debugging
logformat = textall

 # SMSD configuration, see gammu-smsdrc(5)
[smsd]
service = files
 #logfile = syslog
logfile = /var/log/gammu-smsd

 # Increase for debugging information
debuglevel = 0

 # Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/

`1s`, I set it to just `1` but it takes more time than `1s`. Its default value was `60` and I also tried it. — Jerry, Aug 29 '12 at 08:13
"more time" is how many? Did you restart Nagios after chaning? What about `retry_interval`? — quanta, Aug 29 '12 at 08:42
"more time" means about 2 minutes. yes, I restart Nagios. I set `retry_interval=1` but did not find any change in notification time. — Jerry, Aug 29 '12 at 09:24
You haven't even told us the mechanism used to send the SMS messages. Do you have an internal system? Do you send via an external provider, in which case the delay may be through them? etc. You really need to give us something to work with. — John Gardeniers, Aug 29 '12 at 09:34
Did you really google that before, just did it and came with a lot of answer! — Anarko_Bizounours, Aug 29 '12 at 09:40
Also post the `nagios.log` to prove that it takes 2 minutes between detecting the host down and sending the first alert. — quanta, Aug 29 '12 at 09:51

Convert nagios.log timestamp to a human-readable format:

perl -pe 's/(\d+)/localtime($1)/e' nagios.log

[Wed Aug 29 16:58:30 2012] SERVICE ALERT: localhost;SSH;CRITICAL;HARD;4;Connection refused
[Wed Aug 29 16:58:30 2012] SERVICE NOTIFICATION: localhost;localhost;SSH;CRITICAL;notify-service-by-email;Connection refused
[Wed Aug 29 16:58:38 2012] SERVICE NOTIFICATION: localhost;localhost;SSH;CRITICAL;notify-service-by-sms;Connection refused

You can see that it send an email notification immediately and takes only... 8 seconds to send a SMS. The delay (as @John Gardeniers pointed out) is in your SMS system, not Nagios.

With gammu-smsd running you cant use "gammu --sendsms" you need to use gammu-smsd-inject. You need something like this

define command{
        command_name    notify-host-by-sms
        command_line    /usr/bin/gammu-smsd-inject TEXT $CONTACTPAGER$ -text "Alert $HOSTNAME$ is $HOSTSTATE$"
        }

define command{
        command_name    notify-service-by-sms
        command_line    /usr/bin/gammu-smsd-inject TEXT $CONTACTPAGER$ -text "Alert service $SERVICEDESC$ on $HOSTNAME$ is $SERVICESTATE$"
        }
