      function zabbixGraph(): Response
      {
      $zabbixUrl = 'url';
      $zabbixUser = 'user';
      $zabbixPassword = 'passwd';
      $zabbixData = [$zabbixUrl,$zabbixUser, $zabbixPassword];
  
      try {
      $api = new ZabbixApi($zabbixData);
      } catch (Exception $e) {
      echo $e-&gt;getMessage();
      }
      $GetGraphId = $api-&gt;graphGet(array(
      'output' =&gt; 'extend',
      'filter' =&gt; array('host' =&gt;'abros'),
      'search' =&gt; array('name' =&gt; 'Network traffic on')
      ));
      echo($GetGraphId);
