type t = {

}

val dummy : t

Dummy meter, always disabled

val enabled : t -> bool

val of_exporter : Opentelemetry_core.Exporter.t -> t

Create a meter from an exporter

val emit : t -> Opentelemetry_core.Metrics.t list -> unit

Emit metrics directly, bypassing the instrument registry

val emit1 : t -> Opentelemetry_core.Metrics.t -> unit

Emit a single metric directly, bypassing the instrument registry

val add_cb : 
  (clock:Opentelemetry_core.Clock.t ->
    unit ->
    Opentelemetry_core.Metrics.t list) ->
  unit

Register a raw global metrics callback. Called alongside all instruments when collect runs. Use this for ad-hoc metrics that don't fit the structured instrument API.

val collect : t -> Opentelemetry_core.Metrics.t list

Collect metrics from all registered instruments (Instrument.all) and raw callbacks (add_cb), using this meter's clock.

module Instrument = Opentelemetry_core.Instrument

Global registry of metric instruments. Re-exported from Opentelemetry_core.Instrument for convenience.

Convenience aliases for the instrument submodules in Instrument.
