Module `Opentelemetry_cohttp_lwt.Server`Source

Source

val trace : 
  ?service_name:string ->
  ?attrs:Otel.Span.key_value list ->
  ('conn ->
    Cohttp_lwt.Request.t ->
    'body ->
    (Cohttp_lwt.Response.t * 'body) Lwt.t) ->
  'conn ->
  Cohttp_lwt.Request.t ->
  'body ->
  (Cohttp_lwt.Response.t * 'body) Lwt.t

Trace requests to a Cohttp server.

Use it like this:

let my_server callback =
  let callback_traced =
    Opentelemetry_cohttp_lwt.Server.trace
      ~service_name:"my-service"
      (fun _scope -> callback)
  in
  Cohttp_lwt_unix.Server.create
    ~mode:(`TCP (`Port 8080))
    (Server.make () ~callback:callback_traced)

val with_ : 
  ?trace_state:string ->
  ?service_name:string ->
  ?attrs:Otel.Span.key_value list ->
  ?kind:Otel.Span.kind ->
  ?links:Otel.Span_link.t list ->
  string ->
  Cohttp_lwt.Request.t ->
  (Cohttp_lwt.Request.t -> 'a Lwt.t) ->
  'a Lwt.t

Trace a new internal span.

Identical to Opentelemetry_lwt.Trace.with_, but fetches/stores the trace scope in the x-ocaml-otel-traceparent header in the request for convenience.

Source

val get_trace_context : 
  ?from:[ `Internal | `External ] ->
  Cohttp_lwt.Request.t ->
  Otel.Scope.t option

Get the tracing scope from the custom x-ocaml-otel-traceparent header added by trace and with_.

Source

val set_trace_context : 
  Otel.Scope.t ->
  Cohttp_lwt.Request.t ->
  Cohttp_lwt.Request.t

Set the tracing scope in the custom x-ocaml-otel-traceparent header used by trace and with_.

Sourceval remove_trace_context : Cohttp_lwt.Request.t -> Cohttp_lwt.Request.t

Strip the custom x-ocaml-otel-traceparent header added by trace and with_.
