To send push notifications to the Android App you need to apply these changes. Example using PHP but you can also use a shell script etc. In this tutorial i use Debian Squeeze so path and files could be different to your Linux distribution
1) Edit /etc/nagios3/comands.cfg and insert the following code under the "NOTIFICATION COMMANDS" section
# 'server-push-notifications' comannd definition
define command{
command_name server-push-notifications
command_line php /etc/nagios3/send.php $NOTIFICATIONTYPE$ $SERVICEDESC$ "***** Nagios *****nnHost: $HOSTALIAS$nAddress: $HOSTADDRESS$nState: $SERVICESTATE$nnDate/Time: $LONGDATETIME$nnAdditional Info:nn$SERVICEOUTPUT$"
}
2) Create a new file /etc/nagios3/send.php with the following content
class notify_obj {
public $notification = array();
public function __construct() {
$this->notification = array(
"username"=>"",
"password"=>"",
"category"=>"",
"encrypted"=>"",
"flags"=>"",
"service"=>"",
"title"=>"",
"message"=>""
);
}
}
$pushmsg = new notify_obj();
$pushmsg->notification["username"] = "YOUR USERNAME"; // Change this to the username in your app
$pushmsg->notification["password"] = "YOUR PASSWORD"; // Change this to the password set in your app
$pushmsg->notification["category"] = "1";
$pushmsg->notification["encrypted"] = "0";
$pushmsg->notification["flags"] = "0";
$pushmsg->notification["service"] = htmlentities($argv[2], ENT_QUOTES, "UTF-8");
$pushmsg->notification["title"] = htmlentities($argv[1], ENT_QUOTES, "UTF-8");
$pushmsg->notification["message"] = htmlentities($argv[3], ENT_QUOTES, "UTF-8");
$jsonString = json_encode($pushmsg);
// Send JSON Object to Push Server via Curl
$ch = curl_init();
// Replace SERVERNAME with the one mentioned in the settings of the APP.
curl_setopt($ch, CURLOPT_URL, "https://SERVERNAME/pushjson.php");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // See API docs in forum to activate!
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonString);
curl_setopt($ch, CURLOPT_TIMEOUT, '10'); // wait max 10s to complete
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, '8' ); // wait max 8s to connect
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json'
)
);
$result = curl_exec($ch);
curl_close($ch);
// Check $result for any status codes coming back from the server if you need
?>
3) Save the file and assign correct permissions so Nagios can execute it later
chown nagios:nagios /etc/nagios3/send.php
chmod 755 /etc/nagios3/send.php
4) Edit /etc/nagios3/conf.d/contacts_nagios2.cfg and configure the default contact like below. Please take note for this example I removed any email notification from the default contact for better readability. For more options see the Nagios Manual.
define contact{
contact_name root
alias Root
service_notification_period 24x7
service_notification_options w,u,c,r,f
service_notification_commands server-push-notifications
host_notification_period 24x7
host_notification_options d,u,f,r,s
host_notification_commands server-push-notifications
}
5) Save the file and restart Nagios
/etc/init.d/nagios3 restart
