How to use one matric in another matric usinginfluxdb

I have to use one of the matric, which return the count of the one field in another matric.

Could you please help to find out the solution for this

InfluxDB does not have support for subqueries so #A*100 won’t work. But you can do that in one query using InfluxdB math operators or the Math function if not using raw mode for your query.
