配置MySQL数据源

增加DashBoard 选择metric

SELECT
  UNIX_TIMESTAMP(time) as time_sec,
  sum(selectnum)/60 as value,
  'TotalQps' as metric
FROM _status_statistic
WHERE $__timeFilter(time)
group by  time
ORDER BY time ASC

实际下发的SQL
select UNIX_TIMESTAMP(`_status_statistic`.`time`) as `time_sec`,(SUM(`_status_statistic`.`selectnum`) / 60) as `value`,('TotalQps') as `metric` from `_status_statistic_20171121_0` `_status_statistic` where ((`_status_statistic`.`time` >= '2017-11-21 10:03:29') AND (`_status_statistic`.`time` <= '2017-11-21 10:18:29')) group by `_status_statistic`.`time` order by `_status_statistic`.`time` asc


 CREATE TABLE `_status_statistic` (
  `time` datetime DEFAULT NULL,
  `serverip` varchar(32) DEFAULT NULL COMMENT 'ip',
  `selectNum` bigint(20) DEFAULT NULL,
  `loadNum` bigint(20) DEFAULT NULL,
  `insertNum` bigint(20) DEFAULT NULL,
  `failedInsertNum` bigint(20) DEFAULT NULL
) ENGINE= DEFAULT CHARSET=utf8mb4
