Get a logger pre-configured with a fixed set of attributes added to every log record it emits, forwarding to the current global logger. Intended to be called once at the top of a library module.

parameter name
instrumentation scope name (recorded as otel.scope.name)

parameter version
instrumentation scope version (recorded as otel.scope.version)

parameter __MODULE__
the OCaml module name, typically the __MODULE__ literal (recorded as code.namespace)

parameter attrs
additional fixed attributes

val default_logger : Logger.t

A Logger.t that lazily reads the global at emit time

val emit : Opentelemetry_core.Log_record.t -> unit

Emit log with current logger

val log : 
  ?logger:Logger.t ->
  ?attrs:Opentelemetry_core.Key_value.t list ->
  ?trace_id:Opentelemetry_core.Trace_id.t ->
  ?span_id:Opentelemetry_core.Span_id.t ->
  ?severity:Opentelemetry_core.Log_record.severity ->
  string ->
  unit

Create log record and emit it on logger

val logf : 
  ?logger:Logger.t ->
  ?attrs:Opentelemetry_core.Key_value.t list ->
  ?trace_id:Opentelemetry_core.Trace_id.t ->
  ?span_id:Opentelemetry_core.Span_id.t ->
  ?severity:Opentelemetry_core.Log_record.severity ->
  ((('a, Stdlib.Format.formatter, unit, unit) format4 -> 'a) -> unit) ->
  unit

Helper to create a log record, with a suspension, like in Logs.

Example usage: logf ~severity:Severity_number_warn (fun k->k"oh no!! %s it's bad: %b" "help" true)
