Documentation

data ServerMetricsSpec :: Symbol -> MetricType -> Type -> Type where Source #

A specification of the metrics tracked by the server.

The use of the "unit" type () for the "tag structure" type parameter of a metric indicates that we prohibit that metric from being annotated with tags.

Constructors
