Nagios SMS notification with gammu smsd does not work

Question

gammu-smsd configuration:

#vi /etc/gammu-smsdrc

 # Configuration file for Gammu SMS Daemon

 # Gammu library configuration, see gammurc(5)
[gammu]
 # Please configure this!
port = /dev/rfcomm0
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/

It works and I can send SMS from terminal.

Once you get the problem, you should take a look at the logs to see what happens. If it doesn't help, increase the debug level. — quanta, Aug 12 '12 at 17:15
I haven't looked at nagios.log. Thank you....Now I am trying to fix it.... — Jerry, Aug 12 '12 at 17:38
i have added the output of `grep notify-service-by-sms /path/to/nagios.log` above. — Jerry, Aug 12 '12 at 17:51
set `debug_level` to 256, try again and post the `nagios.debug` here. — quanta, Aug 12 '12 at 23:41

It works and I can send SMS from terminal.

Have you tested as root?

output=Error opening device, it doesn't exist.

Make sure that nagios (and apache if you want) has write permission on /dev/rfcomm0.

Check this first:

# ls -l /dev/rfcomm0

Assumming you get:

crw-rw---- 1 root dialout 216, 0 2012-08-10 23:15 /dev/rfcomm0

then add the nagios user to the dialout group:

$ sudo usermod -a -G dialout nagios

and try again.

UPDATE Mon Aug 13 17:57:59 ICT 2012

Set the SUID bit on the command to allow nagios execute gammu on behalf of the root:

# chmod 4755 /usr/bin/gammu

and try again:

# su - nagios -s /bin/bash
$ echo "test" | gammu –sendsms TEXT 0123456789

`# ls -l /dev/rfcomm0` `ls: cannot access /dev/rfcomm0: No such file or directory` – Jerry Aug 13 '12 at 04:40
I take it from your above config `port = /dev/rfcomm0`. – quanta Aug 13 '12 at 04:41
I have connected my phone using blue-tooth and assigned `port = /dev/rfcomm0`. It works and I can send SMS from terminal. I executed `root@khalid:/dev# ls -l` but `rfcomm0` was not found. How SMS is being sent using `/dev/rfcomm0` port(actually it does not exist in `dev` directory)? – Jerry Aug 13 '12 at 05:49
After plugging your phone, type `dmesg` to see which port it is using. – quanta Aug 13 '12 at 05:53
I have copied output of `dmesg` to this [file](http://www.mediafire.com/?owukq71hzg4j1rf). I could not find out actual port from the output. – Jerry Aug 13 '12 at 06:48
Use a pastebin client tool (fpaste, wgetpaste, ...) to paste some ending lines. Dont't upload to mediafire. Switch to `nagios` user (`su - nagios -s /bin/bash`) and send a testing sms with gammu to see what does it say. – quanta Aug 13 '12 at 07:08
when I Switch to nagios user, Should I be root to send SMS?? – Jerry Aug 13 '12 at 11:29
I connected my mobile phone through USB cable and now nagios sends SMS alert. Problem is that it is not real-time. If any service is down, It takes around two minutes to send SMS alert. What should I do?? – Jerry Aug 29 '12 at 05:01
It depends on normal_check_interval, max_check_attempts, ... – quanta Aug 29 '12 at 05:04
I have changed `interval_length=1` (in nagios.cfg file), `normal_check_interval=1` and `max_check_attempts=1` in host definition. Still it takes around one minute. – Jerry Aug 29 '12 at 06:14
http://nagios.sourceforge.net/docs/3_0/configmain.html#interval_length – quanta Aug 29 '12 at 06:22
I have read above link and they have not tested other values for `interval_length` variable. I set it to `1s` that reduced alert time to around one minute. I could not find any way to send sms alert in a second. Is it possible to send SMS alert in one/two second(s)??? – Jerry Aug 29 '12 at 07:12
It is possible. But are you sure you want to do this? Post another topic and insert link here. – quanta Aug 29 '12 at 07:33
