This is an example script to show how to use OSS_SNMP. It requires two arguments:
- the IP address of hostname of a SNMP capable host (with Asterisk SNMP enabled)
- the SNMP v2 community string for that host
For example:
{$argv[0]} 192.168.10.20 public
HELPTEXT;
exit(1);
}
require_once dirname(__FILE__) . '/../OSS_SNMP/SNMP.php';
$host = new \OSS_SNMP\SNMP($argv[1], $argv[2]);
echo "\nSystem information for {$argv[1]}:\n\n";
print_r($host->useSystem()->getAll());
echo "\n\n";
echo "\n\nPlatform details for {$argv[1]}:\n" . "\nVendor: " . $host->getPlatform()->getVendor() . "\nModel: " . $host->getPlatform()->getModel() . "\nOS: " . $host->getPlatform()->getOs() . "\nOS Version: " . $host->getPlatform()->getOsVersion();
echo "\n\n";
echo "Temperature alarm: " . ($host->useExtreme_System_Common()->overTemperatureAlarm() ? 'YES' : 'NO') . "\n";
echo "Temperature : " . $host->useExtreme_System_Common()->currentTemperature() . "C\n";
echo "\n\n";
print_r($host->useExtreme_SwMonitor_Memory()->percentUsage());
echo "\n\n";
exit(0);
