Module Profiler_intf.Timer

A Timer contains only a time stamp and no extra information; however, it is useful because (in Offline) the current time is recorded when measurements are made.

type t
type probe = t
type 'a create_args

The *_args below are instantiated differently for Timers and Probes. See Profiler_intf below.

type 'a record_args
val create : name:string -> t create_args

Create a timer or probe that isn't in a group.

val record : t record_args

record a particular data sample.

module Group : sig ... end

A Group provides a way of grouping multiple probes (or timers). Once grouped, one can measure stats between members of a group -- i.e. the time it takes to get from one probe to the other in the group, or the change in a metric between two probes in a group.
