- INPUT SQL: Enter the desired query (the results being two columns and multiple rows), such as `select _wstart, avg(mem_system) from log.dnodes_info where ts >= $from and ts < $to interval($interval)`. In this statement, $from, $to, and $interval are variables that Grafana replaces with the query time range and interval. In addition to the built-in variables, custom template variables are also supported.
- ALIAS BY: This allows you to set the current query alias.
- GENERATE SQL: Clicking this button will automatically replace the corresponding variables and generate the final executed statement.
- Group by column name(s): `group by` or `partition by` columns name split by comma. By setting `Group by column name(s)`, it can show multi-dimension data if Sql is `group by` or `partition by`. Such as, it can show data by `dnode_ep` if sql is `select _wstart as ts, avg(mem_system), dnode_ep from log.dnodes_info where ts>=$from and ts<=$to partition by dnode_ep interval($interval)` and `Group by column name(s)` is `dnode_ep`.
- Format to: format legend for `group by` or `partition by`. Such as it can display series data by `dnode_ep` if sql is `select _wstart as ts, avg(mem_system), dnode_ep from log.dnodes_info where ts>=$from and ts<=$to partition by dnode_ep interval($interval)` and `Group by column name(s)` is `dnode_ep` and `Format to` is `mem_system_{{dnode_ep}}`.
Follow the default prompt to query the average system memory usage for the specified interval on the server where the current TDengine deployment is located as follows.

- INPUT SQL：输入要查询的语句（该 SQL 语句的结果集应为两列多行），例如：`select _wstart, avg(mem_system) from log.dnodes_info where ts >= $from and ts < $to interval($interval)` ，其中，from、to 和 interval 为 TDengine 插件的内置变量，表示从 Grafana 插件面板获取的查询范围和时间间隔。除了内置变量外，`也支持可以使用自定义模板变量`。
- ALIAS BY：可设置当前查询别名。
- GENERATE SQL： 点击该按钮会自动替换相应变量，并生成最终执行的语句。
- Group by column name(s)： **半角**逗号分隔的 `group by` 或 `partition by` 列名。如果是 `group by` or `partition by` 查询语句，设置 `Group by` 列，可以展示多维数据。例如：INPUT SQL 为 `select _wstart as ts, avg(mem_system), dnode_ep from log.dnodes_info where ts>=$from and ts<=$to partition by dnode_ep interval($interval)`，设置 Group by 列名为 `dnode_ep`，可以按 `dnode_ep` 展示数据。
- Format to： Group by 或 Partition by 场景下多维数据 legend 格式化格式。例如上述 INPUT SQL，将 Format to 设置为 `mem_system_{{dnode_ep}}`，展示的 legend 名字为格式化的列名。
