 As you can see all the recorded metrics start with the `operator.sdk` prefix. `<resource metadata>`, in the table above,
 refers to resource-specific metadata and depends on the considered metric and how the implementation is configured and
 could be summed up as follows: `group?, version, kind, [name, namespace?], scope` where the tags in square
 brackets (`[]`) won't be present when per-resource collection is disabled and tags followed by a question mark are
 omitted if the associated value is empty. Of note, when in the context of controllers' execution metrics, these tag
-names are prefixed with `resource.`. This prefix might be removed in a future version for greater consistency. 
+names are prefixed with `resource.`. This prefix might be removed in a future version for greater consistency.
