check_meteoalarm

This is a Nagios plugin written in PHP to look for weather alerts on the site http://www.meteoalarm.eu. The plugin checks a specific region, which is entered as the full URL of the region as an argument to the script.

The script is released under GNU GPL and hence I can take no responsibility for the correctness of the script. It might not work as expected and should not be be used as a critical tool for weather alerts.

Requirements

PHP version 5 or higher with cURL. To install these packages on Debian/Ubuntu enter sudo apt-get install php5-cli php5-curl. That should be enough to get the script running.

Usage

./check_meteoalarm.php [FULL URL]

For example

./check_meteoalarm.php http://www.meteoalarm.eu/en_UK/0/0/SE002-Sk%E5ne.html

Note that the URL must be the english version (en_UK), otherwise the script can't regex for the correct strings. You can change language on the bottom of the site. Otherwise the direct URL for the english site is http://www.meteoalarm.eu/en_UK/0/0/EU-Europa:.html

Usage within Nagios (on Debian systems)

Step 1: Place the script in /usr/lib/nagios/plugins/

Step 2: Create the following snippet in /etc/nagios3/commands.cfg

define command{
    command_name	check_meteoalarm
	command_line	/usr/lib/nagios/plugins/check_meteoalarm.php $ARG1$
}

Step 3: Create a service definition for a region, for example in your localhost in /etc/nagios3/conf.d/localhost_nagios2.cfg

define service{
    use                             generic-service
    host_name                       localhost
    service_description             Meteoalarm Skane
    check_interval                  15
    retry_interval                  3
    check_command                   check_meteoalarm!'http://www.meteoalarm.eu/en_UK/0/0/SE002-Sk%E5ne.html'
    }
