Added

  • Support for OpenMetrics and Exemplars

Breaking

Changed

  • Refactor histogram internals and provide a fast path for rendering metrics to Prometheus strings when there are many labels shared across different values.
  • Disable custom content encoding for pushgateway delete requests in order to avoid failures from the server when using Content-Encoding: gzip header.
  • Refactor escapeString helper in lib/registry.js to improve performance and avoid an unnecessarily complex regex.
  • Cleanup code and refactor to be more efficient
  • Correct TS types for working with OpenMetrics
  • Updated Typescript and Readme docs for setToCurrentTime() to reflect units as seconds.
  • Do not ignore error if request to pushgateway fails
  • Make sure to reject the request to pushgateway if it times out

Changed

  • Refactor getMetricAsPrometheusString method in the Registry class to use Array.prototype.join
    instead of loop of string concatenations.
  • Also use Array.prototype.map, and object spread instead of an explicit for loop
  • changed: updated the sample output in example/default-metrics.js
  • summary metrics now has a pruneAgedBuckets config parameter
    to remove entries without any new values in the last maxAgeSeconds.
    Default is false (old behavior)

Added

  • Add get method to type definitions of metric classes

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
