Release Notes

siimon/prom-client

v14.1.0

Compare Source

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

v14.0.1

Compare Source

Changed

• changed: typedef for pushgateway to reflect js implementation.

v14.0.0

Compare Source

Breaking

• changed: linearBuckets does not propagate rounding errors anymore.

  Fewer bucket bounds will be affected by rounding errors. Histogram bucket
  labels may change. 6f1f3b2

• changed: The push gateway methods pushAdd(), push() and delete() now
  return Promises instead of accepting a callback:

  // Old:
  gateway.pushAdd({ jobName: 'test' }, (err, resp, body) => {});
  // New:
  gateway
    .pushAdd({ jobName: 'test' })
    .then(({ resp, body }) => {})
    .catch(err => {});
  // or
  const { resp, body } = await gateway.pushAdd({ jobName: 'test' });

• changed: The default nodejs_eventloop_lag_* metrics are now reset every time
  they are observed. This prevents these metrics from "stabilizing" over a long
  period of time and becoming insensitive to small changes. For more info, see
  #​370. 0f444cd

Changed

• Add missing await/thens to examples. 074f339
• Add missing type declaration for client.contentType. 3b66641
• Modernize some label processing code. c9bf1d8

v13.2.0

Compare Source

Changed

• Don't add event listener to process if cluster module is not used.
• fix: set labels for default memory metrics on linux.
• fix: fix DEP0152 deprecation warning in Node.js v16+.
• fix: Set aggregation mode for newer event loop metrics. (Fixes #​418)
• Improve performance of/reduce memory allocations in Gauge.

Added

• feat: added zero() to Histogram for setting the metrics for a given label combination to zero
• fix: allow Gauge.inc/dec(0) without defaulting to 1

v13.1.0

Compare Source

Changed

• fix: push client attempting to write Promise (fixes #​390)
• types: improve type checking of labels
• fix: Summary#observe should throw when adding additional labels to labelset (fixes #​262)

Added

• feat: added the ability to pass labels as an object to labels() and remove()
• Added: More examples with commented output

v13.0.0

Compare Source

Breaking

• changed: The following functions are now async (return a promise):
  registry.metrics()
registry.getMetricsAsJSON()
registry.getMetricsAsArray()
registry.getSingleMetricAsString()

  If your metrics server has a line like res.send(register.metrics()), you
  should change it to res.send(await register.metrics()).

  Additionally, all metric types now accept an optional collect function,
  which is called when the metric's value should be collected and within which
  you should set the metric's value. You should provide a collect function for
  point-in-time metrics (e.g. current memory usage, as opposed to HTTP request
  durations that are continuously logged in a histogram).

• changed: register.clusterMetrics() no longer accepts a callback; it only
  returns a promise.

• removed: v12.0.0 added the undocumented functions registry.registerCollector
  and registry.collectors(). These have been removed. If you were using them,
  you should instead provide a collect function as described above.

Changed

• fix: provide nodejs_version_info metric value after calling registry.resetMetrics() (#​238)
• fix: provide process_max_fds metric value after calling registry.resetMetrics()
• fix: provide process_start_time_seconds metric value after calling registry.resetMetrics()
• chore: improve performance of registry.getMetricAsPrometheusString
• chore: refactor metrics to reduce code duplication
• chore: replace utils.getPropertiesFromObj with Object.values
• chore: remove unused catch bindings
• chore: upgrade Prettier to 2.x
• fix: startTimer returns number in typescript instead of void
• fix: incorrect typings of `registry.getSingleMetric' (#​388)
• chore: stop testing node v13 on CI

Added

• feat: exposed registry.registerCollector() and registry.collectors() methods in TypeScript declaration
• Added: complete working example of a pushgateway push in example/pushgateway.js
• feat: added support for adding labels to default metrics (#​374)
• Added CHANGELOG reminder

v12.0.0

Compare Source

Breaking

• Dropped support for end-of-life Node.js versions 6.x and 8.x
• Dropped the previously deprecated support for positional parameters in
  constructors, only the config object forms remain.
• Default metrics are collected on scrape of metrics endpoint, not on an
  interval. The timeout option to collectDefaultMetrics(conf) is no longer
  supported or needed, and the function no longer returns a Timeout object.

Changed

• chore: remove ignored package-lock.json
• fix: process_max_fds is process limit, not OS (#​314)
• Changed Metric labelNames & labelValues in TypeScript declaration to a generic type T extends string, instead of string
• Lazy-load Node.js Cluster module to fix Passenger support (#​293)
• fix: avoid mutation bug in registry.getMetricsAsJSON()
• fix: improve performance of registry.getMetrics*
• End function of histogram startTimer, when invoked returns the number of seconds
• chore: reindent package.json
• chore: correct var name in processStartTime
• chore: add test for process_start_time_seconds
• chore: spelling corrections in README

Added

• feat: implement GC metrics collection without native(C++) modules.
• feat: implement advanced event loop monitoring
