January 27, 2026 - When running in production, you'll likely want to collect your metrics using an OpenTelemetry exporter integration or another solution (e.g. Datadog can collect these metrics without requiring application changes), but for local testing dotnet-counters is a very convenient tool. dotnet-counters is a .NET tool shipped by Microsoft that you can install by running: ... Alternatively, you can specify a command to run when starting the tool, and it will monitor the target process:

You can also see the metrics collection tutorial for other alternatives. If the dotnet-counters tool is not already installed, use the SDK to install it: > dotnet tool update -g dotnet-counters You can invoke the tool using the following command: dotnet-counters Tool 'dotnet-counters' (version '7.0.430602') was successfully installed. While the example app is still running, use dotnet-counters to monitor the new counter:

The dotnet-monitor global tool is a way to monitor .NET applications in production environments and to collect diagnostic artifacts (for example, dumps, traces, logs, and metrics) on-demand or using automated rules for collecting under specified conditions.

This tutorial shows several examples of collecting and displaying metrics: Populating metrics in Grafana with OpenTelemetry and Prometheus. ... Measurements can also be associated with key-value pairs called tags that allow data to be categorized for analysis. For more information, see Multi-dimensional metrics. Create a new ASP.NET Core app with the following command: dotnet new web -o WebMetric cd WebMetric dotnet add package OpenTelemetry.Exporter.Prometheus.AspNetCore --prerelease dotnet add package OpenTelemetry.Extensions.Hosting

dotnet monitor may fail to collect System.Diagnostics.Metrics if it begins collecting the metric before the target app creates the Meter (note that this is fixed for .NET 8+ apps). Specifying a Meter is done differently than for EventCounter providers. The following example uses MyCounter1 and MyCounter2 on an EventCounter named MyProvider, as well as the MyInstrument instrument on MyCustomMeter and all instruments on the AnotherMeter meter:

.NET supports using any managed object as a lock, either with APIs such as Monitor.Enter or with the lock statement. If one thread already holds a lock while a second thread tries to acquire it, this is called lock contention. Available starting in: .NET 9. This metric reports the same values as calling Timer.ActiveCount.

var odataFilterMetricDef = new ODataQuery<MetricDefinition>("name.value eq 'CpuPercentage'"); metricDefinitions = await readOnlyClient.MetricDefinitions.ListAsync(resourceUri: resourceUri, odataQuery: odataFilterMetricDef, cancellationToken: new CancellationToken());

There are two properties that can be set that will instruct the library to report a metric every minute even if you do not report any values. Applying these properties is done by changing the default settings in the API to AutoReportZero or AutoReportLastValue. Below will describe what these settings mean and when they may be useful. Example of using MetricSetting for advanced options.
