- 7.0.0
- .NET Core specific functionality now targeting .NET 6.0 or greater (all previous versions will be end of life by December 2022).
- Relaxed the API restriction that forbade you to create multiple metrics with the same name but different label names. While this is a Prometheus anti-pattern, it is a standard pattern in other metrics technologies and we will allow it in the name of interoperability.
- Added IMetricFactory.WithLabels() to define static labels per-factory and reduce the effort needed by users when defining static labels in specific scopes.
- Added automatic metric expiration feature, to remove timeseries when they are no longer used after a while. This improves interoperability with other metrics technologies such as .NET Meters.
- (Breaking change) Rewrite of the MeterAdapter functionality to bridge .NET 6 metrics to Prometheus. API remains equivalent, though options class changed. Output format (what metrics are published) is completely different. Now it translates metric names (instead of putting them in labels) and preserves tags (labels) provided via the .NET Meters API. Added sample project to demonstrate functionality. Ref #359
- (Breaking change) Dropped support for .NET Standard 2.0 - now will target specifically .NET 6.0 and .NET Framework 4.6.2. This was already documented before but there was "unofficial" support also for .NET Standard remaining. This is now removed.
- (Breaking change) EventCounterAdapter output format changed to translate counters to Prometheus metrics and to improve usability by publishing both counters and gauges from ambiguous event counters.
- EventCounterAdapter and MeterAdapter are now enabled on startup by default.
- Added some debug metrics to indicate the number of metric families, instances and timeseries being exported by prometheus-net.
- Added typical benchmark results to readme for easy reference, and to show relative speed of the simple versus complex instruments.
- Removed MetricConfiguration.StaticLabels because it had negative performance impact on many code paths that did not use it. The same functionality can be manually implemented in user code. Static labels remain available on registry and factory level.
- When a before-collection metrics update callback throws an exception, it is now logged and ignored instead of breaking all metrics collection.
- EventCounterAdapter now defaults to Informational events only, for reduced performance overhead. Can be configured via callback.
- 6.0.0
- Dropped library support for unsupported .NET runtime versions (.NET 2.1).
- If Razor Pages is enabled, the "page" label is now automatically added to the default HTTP server metrics, unless there is a user-defined label already present with this name.
- The "endpoint" label is now automatically added to the default HTTP server metrics, containing this endpoint routing route pattern of the request, unless there is a user-defined label already present with this name.
- Added integration with .NET EventCounters, which can now be easily exposed as Promtheus metrics (see EventCounterAdapter class).
- Added integration with .NET Meters, which can now be easily exposed as Promtheus metrics (see MeterAdapter class).
- Added ReplaceOnPush option to MetricPusher #305 #322.
- Minimum .NET Framework version is now 4.6.2.
- 5.1.0
- Add support for adding custom label value providers to HTTP server metrics. #347
- 5.0.2
- Bugfix: HttpClientMetrics under concurrent load with long-running requests were leading to broken response streams. #336
- 5.0.1
- Bugfix: PowersOfTenDividedBuckets did not work with >= 10 buckets due to overlap. Now skips overlapping region of generated series.
- 5.0.0
- Added HTTP client metric that measures the response duration (time until response content reading is finished).
- Added "client" label containing the name of HTTP client to HTTP client metrics.
- Added "code" label with HTTP response code to HTTP client metrics. #299
- HTTP client metrics now count responses when they are completed, not when started, to match with HTTP server metrics. Also renamed metric to httpclient_requests_sent_total since it said "received" previously (due to copy-paste error from HTTP server metrics).
- HTTP client metrics are now published via the netstandard package, without requiring ASP.NET Core. #314
- Added Counter.IncTo[Current]TimeUtc().
- 4.2.0
- Added Histogram.PowersOfTenDividedBuckets()
- Improved accuracy of histogram bucket calculations to reduce the likelyhood of seeing 0.00000000000000000001 offsets from expected value due to floating point math.
- Added ConfigureAwait(false) to MetricHandler to help avoid deadlocks in some rare scenarios. #308
- Fix defect where MetricPusher terminated when HttpClient signaled timeout. #302, #293
- No longer need to manually reference ASP.NET Core SDK in csproj file when installing prometheus-net.AspNetCore library. It gets automatically referenced now. #267
- 4.1.1
- Bugfix: HTTP request metrics in 4.1.0 got broken due to typo in middleware helper.
- 4.1.0
- Fixed HttpClient metrics duration that was incorrectly measured. #265

- Added support for defining static labels on registry or metric level. #256
- Added ICollectorRegistry and IMetricFactory for mocking in test code. #268
- Ignore /metrics URL by default in HTTP request metrics.
- Fix overflow in Summary after observing more than uint.MaxValue events. #277

- Added request filtering (authorization) support to standalone MetricServer. #261
- 4.0.0
- Allow arbitrary ASP.NET Core route parameters to be exposed as HTTP metric labels. #225
- Breaking change: some HTTP metrics implementation classes were changed from public to internal. They were never supposed to be public and hopefully nobody ever used them directly. Public documented API did not change.

- Improved wording of some error messages. #169
- Added Counter.IncTo(), Gauge.IncTo(), Gauge.DecTo(). #181
- Added Gauge.Set(DateTimeOffset) and Gauge.IncTo(DateTimeOffset). #181
- Improve .NET Framework 4.6.1 packaging to include the ValueTuple reference automatically. #179
- ASP.NET Core HTTP metrics now capture route data before it is overwritten by an exception handler. #177
- ASP.NET Core HTTP "in progress" metrics now include controller/action labels (ASP.NET Core 3 only).
- Fixed concurrently defect in HTTP metrics that may have caused label values from wrong request to apply. #182
- The HttpListener based MetricServer can now handle more than one concurrent request.
- Added asynchronous "before collect" callbacks, giving user code more flexibility in metric updates.
- Added .Remove() to labeled metric instances for more convenient removal API (previously had to call method on parent instance).
- Added .Unpublish() to labeled metric instances to support temporary unpublishing of a metric, without discarding collected data (e.g. histogram buckets), during periods of data unavailability.
- 3.3.0

- 3.1.1
- Added missing UTF-8 charset to Content-Type header, so non-ASCII characters are interpreted correctly by browsers.
- 3.1.0
- Added ICounter.NewTimer() (adds the value to the counter)
- Eliminated some needless allocations when trying to register a metric that is already registered. #134
- Added IHistogram.Count and IHistogram.Sum to expose aspects of collected data for inspection.
- Added Collector.GetAllLabelValues() to expose the list of child metrics by all their known label values.
