> Input statement: 
>  * set storage group to root.lnset storage group to root.ln               
>  * create timeseries root.ln.dev.ch(status) with datatype=FLOAT, encoding=RLE, compression=SNAPPY tags(tag1=v1) attributes(attr1=v1);               
>  * COUNT NODES root.ln.* LEVEL=2
> It shows:
>  * Msg: 500: ln does not have the child node *
> If I change the count nodes command to:
>  * COUNT NODES root.ln LEVEL=2
> the result is:
> |count|
> |1|
>  Total line number = 1
> That is expected. "COUNT NODES root.ln.* LEVEL=2 " and "COUNT NODES root.ln LEVEL=2 " are equivalent. So, the former command should lead to the same result.
