What you expected to happen
在ClickHouse Query Analysis dashboard展示数据的时候存在有两个问题：
Q1: 数据查询慢，默认查询最近12h，数据加载很慢，调整成6h、3h、30m、15m、5m间隔数据加载还是慢
Q2：数据加载成功后面板突然变no data， 数据加载好过几秒，面板上面展示的都是no data，点击右上角 Refresh Dashboard按钮并不生效。

@chrisdamon ，前往这个 dashboard 评估下 clickhouse 的性能表现是否正常，以及 clickhouse 所在节点的负载是否很高。
另外能否提供一些规模信息：
- agent 数量
- server 数量
- server cpu/mem 配置
