StatsLogging (infer.IBase.StatsLogging)

val log_many : LogEntry.t list -> unit

Log several events in one go. Useful when you do custom aggregations and have a place to log all aggregated results at once.

val log_count : label:string -> value:int -> unit

Log anything that can be counted. Events will be prefixed with "count."

val log_duration : label:string -> duration_us:int -> unit

Log elapsed time. Events will be prefixed with "time."

val log_message : label:string -> message:string -> unit

Log a string. Event is prefixed with "msg."

val log_message_sampled : 
  label:string IStdlib.IStd.Lazy.t ->
  message:string IStdlib.IStd.Lazy.t ->
  sample_rate:int ->
  unit

val log_message_with_location : 
  label:string ->
  loc:string ->
  message:string ->
  unit

val log_message_with_location_sampled : 
  label:string IStdlib.IStd.Lazy.t ->
  loc:string IStdlib.IStd.Lazy.t ->
  message:string IStdlib.IStd.Lazy.t ->
  sample_rate:int ->
  unit

val execute_with_time_logging : string -> (unit -> 'a) -> 'a

A helper to log execution time of a particular function. Use this to measure a performance of a given function. Example:

let f a b = <some code>
let f a b = StatsLogging.execute_with_time_logging "f" (fun () -> f a b)
