PHP通过Zabbix API获取服务器监控信息
开源监控系统Zabbix提供了丰富的API,供第三方系统调用。
基本步骤如下:
1、获取合法认证;连接对应Zabbix URL,并提供用户名和密码,HTTP方法为“POST”,HTTP头部类型为“application/json”
1 public function zabbixJsonRequest($uri, $data) { 2 try{$json_data = json_encode($data); 3 $c = curl_init(); 4 curl_setopt($c, CURLOPT_URL, $uri); 5 curl_setopt($c, CURLOPT_CUSTOMREQUEST, "POST"); 6 curl_setopt($c, CURLOPT_RETURNTRANSFER, true); 7 curl_setopt($c, CURLOPT_POST, $json_data); 8 curl_setopt($c, CURLOPT_POSTFIELDS, $json_data); 9 curl_setopt($c, CURLOPT_HTTPHEADER, array( 10 'Content-Type: application/json', 11 'Content-Length: ' . strlen($json_data)) 12 ); 13 curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false); 14 $result = curl_exec($c); 15 16 return json_decode($result, true); 17 }catch(Exception $e) { 18 CCLog::LogErr('ZabbixInfoLogic: zabbixJsonRequest Err ->' . $e->getMessage()); 19 return array(); 20 } 21 }
1 /** 2 * @Zabbix鉴权 3 * @param $uri Zabbix地址 4 * @param $username Zabbix用户名 5 * @param $password Zabbix密码 6 * @return 权限 7 */ 8 public function zabbixAuth($uri, $username, $password) { 9 try{$data = array( 10 'jsonrpc' => "2.0", 11 'method' => "user.login", 12 'params' => array( 13 'user' => $username, 14 'password' => $password 15 ), 16 'id' => "1" 17 ); 18 $response = $this->zabbixJsonRequest($uri, $data); 19 return $response['result']; 20 }catch(Exception $e) { 21 CCLog::LogErr('ZabbixInfoLogic: zabbixAuth Err ->' . $e->getMessage()); 22 return array(); 23 } 24 }
2、调用API获取数据;取得认证后,根据需要POST封装好的data,格式为json,配置不同的方法获取需要的数据。方法列表可在官方网站(https://www.zabbix.com/documentation/3.0/manual/api/reference)查阅。以下实例根据主机IP地址获取主机ID
1 /** 2 * @根据IP获取hostid 3 * @param $uri Zabbix地址 4 * @param $authtoken 认证信息 可通过上述zabbixAuth方法获取 5 * @param $ip 主机IP地址 6 * @return hostid 获取主机ID 7 */ 8 public function zabbixGetHostIdByIp($uri, $authtoken,$ip) { 9 try{$data = array( 10 'jsonrpc' => "2.0", 11 'method' => "host.get", 12 'params' => array( 13 "output"=>[ "host" ], 14 "filter" => array( 15 "ip" => $ip, 16 17 ) 18 ), 19 'id' => "1", 20 'auth' => $authtoken 21 ); 22 $response = $this->zabbixJsonRequest($uri, $data); 23 return $response['result'][0]['hostid']; 24 }catch(Exception $e) { 25 CCLog::LogErr('ZabbixInfoLogic: zabbixGetHostIdByIp Err ->' . $e->getMessage()); 26 return array(); 27 } 28 }
