Learn about the C Sharp Integration.

C Sharp Integration

This Wavefront C# integration explains how to send C# application metrics to Wavefront.

Wavefront provides several C# SDKs for different purposes on Github:

In the Setup tab, the integration includes sample code based on wavefront-appmetrics-sdk-csharp for sending metrics to a Wavefront proxy or using direct ingestion.

This is a custom integration. You can send your own metrics and create your own dashboards.

C# Setup

The Wavefront plugin for AppMetrics adds Wavefront reporters and an abstraction that supports tagging at the reporter level. The reporters support sending metrics to Wavefront using the Wavefront proxy or using direct ingestion.

Install NuGet package

Using Package Manager Console

PM> Install-Package Wavefront.AppMetrics.SDK.CSharp

Using .NET CLI Console

> dotnet add package Wavefront.AppMetrics.SDK.CSharp

Option 1. Create a Wavefront Proxy Reporter and Register Metrics

Follow these steps for sending metrics to a Wavefront proxy. See Option 2 for sending metrics directly to a Wavefront service.

Step 1. Set up Wavefront Proxy

If you do not have a Wavefront proxy installed on your network and reachable from your C# application, install a proxy. You configure the Wavefront proxy hostname and port (by default 2878) when you create the reporter.

Step 2. Create a Wavefront Proxy Reporter and Register Metrics

To create a reporter which will emit data to a Wavefront proxy every 5 seconds:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using App.Metrics;
using App.Metrics.Counter;
using App.Metrics.Reporting.Wavefront.Builder;
using App.Metrics.Scheduling;
using Wavefront.SDK.CSharp.Common;
using Wavefront.SDK.CSharp.Proxy;

string proxyHost = "wavefront.proxy.hostname";
int metricsPort = 2878;

IWavefrontSender wavefrontProxyClient = new WavefrontProxyClient.Builder(proxyHost)
    .MetricsPort(metricsPort)
    .Build();

IMetricsRoot metrics = new MetricsBuilder()
    .Configuration.Configure(options =>
    {
        options.DefaultContextLabel = "service";
        options.GlobalTags = new GlobalMetricTags(new Dictionary<string, string>
        {
                        { "dc", "us-west-2" },
                        { "env", "staging" }
        });
    })
    .Report.ToWavefront(options =>
    {
        options.WavefrontSender = wavefrontProxyClient;
        options.Source = "app-1.company.com";
    })
    .Build();

CounterOptions evictions = new CounterOptions
{
    Name = "cache-evictions"
};
metrics.Measure.Counter.Increment(evictions);

var scheduler = new AppMetricsTaskScheduler(TimeSpan.FromSeconds(5), async () =>
{
    await Task.WhenAll(metrics.ReportRunner.RunAllAsync());
});
scheduler.Start();

Option 2. Create a Wavefront Direct Reporter and Register Metrics

You can send metrics directly to a Wavefront service, discussed next. Option 1 above explains how to send metrics to a Wavefront proxy.

To create a reporter which will emit data to a Wavefront service every 5 seconds:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using App.Metrics;
using App.Metrics.Counter;
using App.Metrics.Reporting.Wavefront.Builder;
using App.Metrics.Scheduling;
using Wavefront.SDK.CSharp.Common;
using Wavefront.SDK.CSharp.DirectIngestion;

string wavefrontServer = "https://YOUR_CLUSTER.wavefront.com";
string token = "YOUR_API_TOKEN";

IWavefrontSender wavefrontDirectIngestionClient =
    new WavefrontDirectIngestionClient.Builder(wavefrontServer, token).Build();

IMetricsRoot metrics = new MetricsBuilder()
    .Configuration.Configure(options =>
    {
        options.DefaultContextLabel = "service";
        options.GlobalTags = new GlobalMetricTags(new Dictionary<string, string>
        {
                        { "dc", "us-west-2" },
                        { "env", "staging" }
        });
    })
    .Report.ToWavefront(options =>
    {
        options.WavefrontSender = wavefrontDirectIngestionClient;
        options.Source = "app-1.company.com";
    })
    .Build();

CounterOptions evictions = new CounterOptions
{
    Name = "cache-evictions"
};
metrics.Measure.Counter.Increment(evictions);

var scheduler = new AppMetricsTaskScheduler(TimeSpan.FromSeconds(5), async () =>
{
    await Task.WhenAll(metrics.ReportRunner.RunAllAsync());
});
scheduler.Start();
