Metric Registries

A registry is a collection of one or more metrics. By default, metrics are added to the object returned by global_registry(), but new registries can also be created with registry(). Use collect_metrics() to return all metrics that a registry is aware of, or render_metrics() to render all of them in aggregate.

registry()

global_registry()

collect_metrics(registry = global_registry())

render_metrics(registry = global_registry())

Arguments

registry	A Registry object, defaulting to the shared global one.

Value

registry() and global_registry() return Registry objects (see Details), while collect_metrics() returns a list of metrics and render_metrics() returns a string.

Details

Registry objects have methods, but they are not intended to be called by users and have no stable API.
