Module Core_profiler.Online.Probe

A Probe records some integer value that is passed to at along with a timestamp.

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.
