trait MetricNamespace extends AnyRef

A MetricNamespace is essentially just an address prefix and set of tags. It is needed when getting or creating collectors. The namespace address is prefixed onto the given address for the collector to create the full address. Tags are added to each collector under under this context.

    Retrieve a Collector of a specific type by address, creating a new one if it does not exist.

    Retrieve a Collector of a specific type by address, creating a new one if it does not exist. If an existing collector of a different type already exists, a DuplicateMetricException will be thrown.

    T

    The Collector to be retrieved.

    address

    Address meant to be relative to this MetricNamespace's namespace

    f

    Function which takes in an absolutely pathed MetricAddress, and a CollectorConfig and returns an instance of a Collector

    returns

    A newly created instance of Collector, created by f or an existing Collector if one already exists with the same MetricAddress
