LSI MegaRaid monitoring

Hi,

I have added the below code to server/lib/classes/monitor_tools.inc.php to return the raid status for our LSI raid controllers.

PHP:

                /*
                * LSI MegaSAS Controller
                */

                if (file_exists('/usr/sbin/megacli')) {

                        $data['output'] = shell_exec('megacli -LDInfo -Lall -aAll');

                        $state = 'ok';

                        if (strpos($data['output'], 'Optimal') !== false) {
                                $this->_setState($state, 'ok');
                        }
                        else if (strpos($data['output'], 'Degraded') !== false) {
                                $this->_setState($state, 'critical');
                        }
                        else if (strpos($data['output'], 'Offline') !== false) {
                                $this->_setState($state, 'critical');
                        } else {
                                $this->_setState($state, 'critical');
                        }
                }
