Nagios SMS notification with gammu smsd does not work

ubuntu nagios sms

7,105

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

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.
Greg Petersen almost 12 years

How about nagios.log?
Jerry almost 12 years

I haven't looked at nagios.log. Thank you....Now I am trying to fix it....
Jerry almost 12 years

i have added the output of grep notify-service-by-sms /path/to/nagios.log above.
Greg Petersen almost 12 years

set debug_level to 256, try again and post the nagios.debug here.

Greg Petersen almost 12 years

I take it from your above config port = /dev/rfcomm0.
Jerry almost 12 years

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)?
Greg Petersen almost 12 years

After plugging your phone, type dmesg to see which port it is using.
Jerry almost 12 years

I have copied output of dmesg to this file. I could not find out actual port from the output.

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.

when I Switch to nagios user, Should I be root to send SMS??
Jerry almost 12 years

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??
Greg Petersen almost 12 years

It depends on normal_check_interval, max_check_attempts, ...
Jerry almost 12 years

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 almost 12 years

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)???
Greg Petersen almost 12 years

It is possible. But are you sure you want to do this? Post another topic and insert link here.
