Module Opentelemetry.TraceSource

Traces.

See the spec

Sourcetype span = Span.t
Sourceval make_resource_spans : ?service_name:??? -> ?attrs:??? -> Proto.Trace.span list -> Proto.Trace.resource_spans
Sourceval emit : ?service_name:??? -> ?attrs:??? -> span list -> unit

Sync emitter.

This instructs the collector to forward the spans to some backend at a later point.

NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.

Sourcetype scope = Scope.t = {
  1. trace_id : Trace_id.t;
  2. span_id : Span_id.t;
  3. mutable events : Event.t list;
  4. mutable attrs : Span.key_value list;
}
  • deprecated use Scope.t
Sourceval add_event : Scope.t -> (unit -> Event.t) -> unit
  • deprecated use Scope.add_event
Sourceval add_attrs : Scope.t -> (unit -> key_value list) -> unit
  • deprecated use Scope.add_attrs
Sourceval with_ : ?force_new_trace_id:??? -> ?trace_state:??? -> ?service_name:??? -> ?attrs:??? -> ?kind:??? -> ?trace_id:??? -> ?parent:??? -> ?scope:??? -> ?links:??? -> string -> (Scope.t -> 'a) -> 'a

Sync span guard.

  • parameter force_new_trace_id

    if true (default false), the span will not use a surrounding context, or scope, or trace_id, but will always create a fresh new trace ID.
