v14.1.0

Changed

• types: converted all the generic Metric types to be optional

• The done() functions returned by gauge.startTimer() and
  summary.startTimer() now return the timed duration. Histograms already had
  this behavior.

• types: fixed type for registry.getMetricsAsArray()

• Improve performance of gague.inc() and gauge.dec() by calling hashObject() once.

Added

• The processResources metric was added, which keeps a track of all sorts of
  active resources. It consists of the following gauges:

  • nodejs_active_resources - Number of active resources that are currently
    keeping the event loop alive, grouped by async resource type.
  • nodejs_active_resources_total - Total number of active resources.
    It is supposed to provide the combined result of the processHandles and
    processRequests metrics along with information about any other types of
    async resources that these metrics do not keep a track of (like timers).

• Support gzipped pushgateway requests
