Influxdb 如何查询所有XDB_内部数据库测量值？

我无法使用Influxql从InfluxDB的内部数据库查询以下测量值：

database
write
shard

请参见以下命令的结果：

> show databases
name: databases
name
----
_internal

>use _internal

> show measurements
name: measurements
name
----
cq
database
httpd
queryExecutor
runtime
shard
subscriber
tsm1_cache
tsm1_engine
tsm1_filestore
tsm1_wal
write

> select * from database limit 1;
ERR: error parsing query: found fron, expected FROM at line 1, char 10
> select * from write limit 1;
ERR: error parsing query: found WRITE, expected identifier at line 1, char 15
> select * from shard limit 1;
ERR: error parsing query: found SHARD, expected identifier at line 1, char 15

但我可以成功地查询其他一些度量

> select * from queryExecutor limit 1;
name: queryExecutor
time                hostname              queriesActive queriesExecuted queriesFinished queryDurationNs recoveredPanics

我如何在所有可用的测量数据中查询/提取流入数据库的数据？

嗯，，，，太晚了。。。但我正在想办法 在某些情况下，如果查询的标识符之一是InfluxQL关键字，则会发生扩展标识符错误。若要成功查询也是关键字的标识符，请将该标识符与大引号关联

select * from "database"
