Using SMS gateway with Nagios
Sending notifications from Nagios using SMS gateway HWg-SMS-GW.
A plug-in for HWg-SMS-GW, created in cooperation with Netways, allows sendong
SMS messages from Nagios system.
Nagios plug-in notify-poseidon-sms.pl takes notifications about changes on the monitored devices
and transfers them via HTTP protocol to HWg-SMS-GW, which then sends an SMS message.
Installation
The following steps are based on standard Ubuntu server installation process Some folders
or commands can vary due to different Linux distribution used.
2.1) Download the notify-poseidon-sms.pl plug-in from https://www.netways.org/projects/plugins/files
do adresáře /usr/lib/nagios and set the setup rights.
nagios-server:~# cd /usr/lib/nagios
nagios-server:~# wget https://www.netways.org/attachments/download/262/notify-poseidon-sms.pl
nagios-server:~# chmod a+x notify-poseidon-sms.pl

2.2) Send a test SMS to verify the functions of the plug-in and HWg-SMS-GW. Parametr -H specifies
an IP addresuś of the HWg-SMS-GW device designated for sending the SMS messages. Enter the
recipients phone number for receiving the message using the -D parameter.
In case the plug-in start fails and an error message shows Can't locate LWP.pm, it is necessary to
install a Perl module LWP for HTTP protocol support. This can be done on Ubuntu or Debian by a
command:
Nagios settings
Document recommended for basic Nagios setup:
http://www.hw-group.com/support/an38/index_cz.html
3.1) A support for sending SMS messages with the notify-poseidon-sms.pl plug-in can be added by
creating a file /etc/nagios3/notify-poseidon-sms.cfg:
Note: The whole command_line definition text has to be in one line in order to work correctly.
Note, do not forget to change the -H parameter to an actual IP address (eventually to a DNS
name) of your HWg-SMS-GW device.
SMS text is assembled by the -M parameter. A list of supported variables (macros) can be found on
http://nagios.sourceforge.net/docs/3_0/macrolist.html
nagios-server:~# cd /usr/lib/nagios
nagios-server:~# ./notify-poseidon-sms.pl -M "Test message" -H 192.168.1.1 -D [phone]

3.2) Define contacts and contact groups for SMS messaging in a file
/etc/nagios3/conf.d/contacts_nagios.cfg.
Note: In case you want to send notifications to multiple phone numbers, create a contact for every
phone number and enter each contact into a memebers parameters in a contactgroup (divided with ,
).
In case you are using a standard Nagios configuration and want to add SMS sending for all devices
and services, do not create a contactgroup and add only peter-gsm to the admins group. The setup is
then complete and the notifications will be sent also via SMS after restarting the Nagios service
(points 3 and 4).
3.3) Adding SMS notification options to selected sevices and services can be done in their definition,
by adding a contact_groups parameter, for example:
Note: Contacts are usually defined in the device's or service's templates, adding contact_groups
parameters will rewrite the pre-set template. This example is based in a standard settings of an
admins contact group, which uses e-mails for sending notifications. Only SMS messages will be sent
after adding "contact_groups sms" parameter.
3.4) A restart of Nagios needed to activate the changes.
define contact {
contact_name peter-gsm
alias Peters GSM phone

host_notification_period 24x7
service_notification_options w,u,c,r
