How to use the queue.alertRepeatGap function in queue

.then(function(data) {
                       thisObj.vhostData = data[0];
                       util.flattenStatistics( thisObj.vhostData );
                       var connections = thisObj.vhostData[ "connections" ];
                       var queues = thisObj.vhostData[ "queues" ];
                       var exchanges = thisObj.vhostData[ "exchanges" ];

                       thisObj.updateHeader();


                       // update alerting info
                       var alertRepeatGap = formatter.formatTime( thisObj.vhostData["queue.alertRepeatGap"] );

                       thisObj.alertRepeatGap.innerHTML = alertRepeatGap.value;
                       thisObj.alertRepeatGapUnits.innerHTML = alertRepeatGap.units;


                       var alertMsgAge = formatter.formatTime( thisObj.vhostData["queue.alertThresholdMessageAge"] );

                       thisObj.alertThresholdMessageAge.innerHTML = alertMsgAge.value;
                       thisObj.alertThresholdMessageAgeUnits.innerHTML = alertMsgAge.units;

                       var alertMsgSize = formatter.formatBytes( thisObj.vhostData["queue.alertThresholdMessageSize"] );

                       thisObj.alertThresholdMessageSize.innerHTML = alertMsgSize.value;
                       thisObj.alertThresholdMessageSizeUnits.innerHTML = alertMsgSize.units;

                       var alertQueueDepth = formatter.formatBytes( thisObj.vhostData["queue.alertThresholdQueueDepthBytes"] );
