Severity level of a log event

type flags = Opentelemetry_proto.Logs.log_record_flags =
  1. | Log_record_flags_do_not_use
  2. | Log_record_flags_trace_flags_mask
val make : ?time:Timestamp_ns.t -> ?observed_time_unix_nano:Timestamp_ns.t -> ?severity:Opentelemetry_proto.Logs.severity_number -> ?log_level:string -> ?flags:int32 -> ?trace_id:Trace_id.t -> ?span_id:Span_id.t -> value -> t

Make a single log entry

val make_str : ?time:Timestamp_ns.t -> ?observed_time_unix_nano:Timestamp_ns.t -> ?severity:Opentelemetry_proto.Logs.severity_number -> ?log_level:string -> ?flags:int32 -> ?trace_id:Trace_id.t -> ?span_id:Span_id.t -> string -> t

Make a log entry whose body is a string

val make_strf : ?time:Timestamp_ns.t -> ?observed_time_unix_nano:Timestamp_ns.t -> ?severity:Opentelemetry_proto.Logs.severity_number -> ?log_level:string -> ?flags:int32 -> ?trace_id:Trace_id.t -> ?span_id:Span_id.t -> ('a, Format.formatter, unit, t) format4 -> 'b

Make a log entry with format

val emit : ?service_name:string -> ?attrs: (string * [< `Bool of bool | `Float of float | `Int of int | `None | `String of string ]) list -> t list -> unit

Emit logs.

This instructs the collector to send the logs to some backend at a later date. NOTE be careful not to call this inside a Gc alarm, as it can cause deadlocks.
