Hi all ; I followed this tutorial <a href="http://www.nagiosexchange.org/cgi-bin/pages/Detailed/1855.html" target="_blank">http://www.nagiosexchange.org/cgi-bin/pages/Detailed/1855.html</a> I would like to test the sms alert system from a GSM SMS gateway , I have added these lines in commands.cfg define command{ command_name service_notify_with_sms command_line $USER1$/notify_sms -a MY_MOBILE_NUMBER -u MY_USER_NAME -p MY_PASSWORD -m \ '$NOTIFICATIONTYPE$:$HOSTNAME$ is $SERVICESTATE$ ($SERVICEOUTPUT$)\' -t $CONTACTPAGER$ } I have 3 doubts doubt 1) is the above configuration correct ? where MY_MOBILE_NUMBER = my cell phone number and MY_USER_NAME = sms gateway user account and MY_PASSWORD = sms gateway user password doubt 2 ) why I have to add again the following config section ? i mean the purpose of the following lines ? define command{ <pre><code> command_name host_notify_with_sms command_line /usr/lib/nagios/plugins/notify_sms -a 1012345 -u myusername_for_gw -p mypassword_for_gw -m \'$NOTIFICATIONTYPE$: $HOSTNAME$ is $HOSTSTATE$ ($HOSTOUTPUT$)\' -t $CONTACTPAGER$ </code></pre> } doubt 3) if I added the 2 define command sections in commands.cfg as in the website , can I get an sms alert ?anything else I have to add in localhost.cfg ? (where I have services to check ssh,ping,http in the localhost . ) These are the Nagios packages I have in my box nagios-2.9_1 nagios-plugins-1.4.9_1,1 <a href="http://www.nagiosexchange.org/cgi-bin/jump.cgi?ID=1855&view=File2;d=1" target="_blank">notify_sms-1.1.tar.gz</a> I untared this notify_sms-1.1.tar.gz package and copied it to /usr/local/libexec/nagios/ (in this directory I hvae all the check_ssh check_ping etc etc comamnds by default) Let me request you to clarify my doubts , sorry for my ignorance , NOTE : The SMS gateway is in another PC , but I configured Nagios in a localbox ,but both machines in the same network . so can I use this SMS gateway ? how to make this sms gateway service available for nagios box ? Thanks in Advance kkchn
