Here, "metric" is a noun that means a standard of measurement. It can also be an adjective referring to or relating to the "metric system," a specific way of measuring things. Ex: The most effective metric we have is being able to count the click rates on the adverts. Ex: We're trying out new metrics to see how many people sign up within a week. Ex: I prefer the metric system as opposed to the imperial system.
