Show tag value for a specific measure

Hi guys, simple yet complicated question, how can i get all the values of a tag? sample here ->

i know i can use SHOW TAG VALUES WITH KEY = “type_instance” but i would want only the cpu_value measurement ones.
I know i can also use “select type_instance,value from cpu_value” but i don’t want on the results to have the value.

is there any way to acomplish this?

solved it myself:

SHOW TAG VALUES FROM “cpu_value” WITH KEY IN (“type_instance”)
