There are a bunch of custom metrics that looks like:
metric.name.key1
metric.name.key2
...
There is a template variables dropdown (https://docs.datadoghq.com/dashboards/template_variables/) on the dashboard that contains all keys. (Name of the variable is $key and values key1, key2..)
The metrics query like this works fine:
avg:metric.name.key1{*}.as_count()
But is it possible to parametrize the query with the $key variable by concatenation with the part of the name of metric? So it would look like this:
avg:metric.name.$key{*}.as_count()
As I know, it is possible to something like that by using tags but unfortunately, there are no any metrics with the tag "key".
