prometheus-net 3.1.4-pre-000016-95d0170

* 3.1.4 - Fix timezone mismatch in Summary that led to unintended delays in buffer flushing. #149 * 3.1.3 - Fix regression introduced in 3.1.0 where MetricPusher does not always flush metrics before stopping. * 3.1.2 - Fix defect where Histogram batch observations only incremented sum by one value, instead of entire batch. #147 * 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. - Metric export is now asynchronous internally to be compatible with ASP.NET Core 3.0 default configuration. - Added CollectorRegistry.CollectAndExportAsTextAsync() to support metric data export via arbitrary custom endpoints. * 3.0.3 - Now backward compatible with ASP.NET Core 2.1 (was 2.2+) * 3.0.2 - Fix defect where histogram sum failed to increment. * 3.0.1 - Fix ObjectDisposedException in MetricPusher. * 3.0.0 - Added HTTP request metrics for ASP.NET Core. - Somewhat more realistic examples in readme. - Metrics exporter is now significantly more CPU and memory-efficient. - Added Observe(value, count) to histogram metric, enabling multiple observations with the same value to be counted. - Added CountExceptions() and MeasureInProgress() helper extensions. - Adjusted API to better conform to Prometheus client library guidelines in terms of default values. - Breaking change: assemblies are now strong-named. - Breaking change: removed "windows" from built-in metric names as they are not Windows-specific. - Breaking change: removed support for protobuf export format (it is no longer used by Prometheus). - Breaking change: API surface cleaned up, removed some legacy methods, made many internal types actually internal. - Breaking change: "on demand collectors" concept replaced with simpler "before collect callbacks". Works the same, just less code needed to use it and fewer possible error conditions. - Breaking change: removed support for "custom collectors", as this was a very special use case that did not benefit at all from the main functionality of the library. Just generate a Prometheus exporter output document yourself if you need to export arbitrary data. * 2.1.3 - Fixed wrong case used for metric type in the export data format. Should always be lowercase. #96 * 2.1.2 - Fixed potential conflict when using pushgateway and also other exporter libraries (see #89) * 2.1.1 - Various minor fixes (see issues on GitHub for details). * 2.1.0 - Add MetricOptions and subclasses for more extensible API (old API surface remains available) - Add SuppressInitialValue to metric configuration (ref https://www.robustperception.io/existential-issues-with-metrics/) - Add .WithLabels() as alternative to .Labels() for fewer annoying Intellisense conflicts. * 2.0.0 - Targeting .NET Standard 2.0 as minimum version (.NET Framework 4.6.1, .NET Core 2.0 and Mono 5.4) - Added ASP.NET Core middlware - Added possibility to signal a failed scrape from on-demand collectors - Removed dependency on Reactive Extensions - Minor breaking changes to API - Performance improvements for hot-path code - Removed mostly obsolete PerfCounterCollector class - Fixed NuGet package contents to remove assemblies from dependencies - Various minor fixes (see issues on GitHub for details) * 1.3.4 - Added support for .NET 4.5 using System.Reactive 3.1.1. - .NET 4.0 support continues to target Rx 2.5 * 1.2.4: - Fixed MetricPusher not flushing metrics when stopped * 1.2.3: - Fixed label values escaping for ASCII formatter * 1.2.2: - PushGateway support - Various internal improvements (replaced locks with Interlocked operations) * 1.1.4: - Fixed some metrics not updating, added process ID metric - Replaced lock statements in Counter and Gauge with CAS * 1.1.3: - optionally use https in MetricServer * 1.1.2: - using UTF-8 in text formatter - catching exceptions in MetricServer http loop * 1.1.1: - disposing of MetricServer loop on Stop() * 1.1.0: - Renamed some metric names to be in-line with prometheus guidelines (breaking change as far as the exported metrics are concerned) * 1.0.0: - Add CPU, num handles, start time, num threads metrics to dot net stats collector - Made DotNetStatsCollector default (previously it was PerfCounterCollector) * 0.0.11: - Summary metric ported from go * 0.0.10: - Fix header writing order * 0.0.9: - Generalise scraping so it can be called externally without using the embedded http handler * 0.0.8: - Introduced interfaces for all the metrics to make unlabelled collectors and their children polymorph * 0.0.7: - Added the notion of OnDemandCollectors + a DotNetStatsCollector to avoid having to use .net perf counters * 0.0.6: - Do not create unlabelled metric if label names are specified * 0.0.5: - Allow specifying hostname in URL - Fix null ref exception if 'Accept' header is not specified * 0.0.3 - initial version
