PHP通过Zabbix API获取服务器监控信息

Posted 2020-10-13 himismad

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     }
