Dotnet Runtime Metrics

Runtime metrics for .NET

.NET Runtime Dashboard

This Grafana dashboard provides comprehensive monitoring of .NET Core runtime metrics, giving you deep insights into your application’s performance, memory management, threading, and exception handling.

Source Code

Source code for this dashboard is available at: https://github.com/petabridge/dotnet-grafana-dashboards/blob/master/runtime/README.md

Features

Exception Monitoring: Track both handled and unhandled exceptions
Garbage Collection: Monitor GC performance, heap sizes, and collection frequencies
JIT Compilation: Track JIT compilation times and methods
ThreadPool: Monitor thread pool utilization and CPU usage
Assembly Loading: Track loaded assemblies and loading times
Memory Usage: Monitor detailed memory metrics across different generations

Prerequisites

To use this dashboard, you need to have the following OpenTelemetry.Instrumentation.Runtime package installed in your .NET application:

<ItemGroup>
    <PackageReference Include="OpenTelemetry.Instrumentation.Runtime" Version="{version}" />
</ItemGroup>

This dashboard is designed to work with Prometheus and the OTLP Exporter.

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddOpenTelemetry()
    .WithMetrics(metrics =>
    {
        metrics
            // OTHER METRICS SOURCES
            .AddRuntimeInstrumentation();
            
    })
    // traces, et al
    .UseOtlpExporter();

var app = builder.Build();
