# Telemetry.Poller

Allows to periodically collect measurements and dispatch them as Telemetry events.

Poller provides a convenient API for specifying functions called periodically to dispatch
measurements as Telemetry events. It also includes helpers for measuring Erlang virtual machine

# define custom function dispatching event with value you're interested in
defmodule ExampleApp.Measurements do
  def dispatch_session_count() do
    Telemetry.execute([:example_app, :session_count], ExampleApp.session_count())

  measurements: [
    # include custom measurement
    {ExampleApp.Measurements, :dispatch_session_count, []}
    # include default VM measurements
    | Telemetry.Poller.vm_measurements()
  period: 10_000 # configure sampling period
