Azure Monitor

This section describes how to export monitoring data to Azure Monitor. It will show both how to export metrics, and also health check data.

Metrics export

To export metrics information, you need to install the following nuget packages:

• OpenTelemetry.Extensions.Hosting
• Azure.Monitor.OpenTelemetry.Exporter

Next in your Program.cs add the following code:

builder.Services.AddOpenTelemetry()
    .WithMetrics(builder =>
    {
        builder.AddAzureMonitorMetricExporter(o =>
        {
            o.ConnectionString = "{your connection string}";
        });
        builder.AddView((instrument) =>
        {
            return new MetricStreamConfiguration()
            {
                Name = $"{instrument.Meter.Name}.{instrument.Name}"
            };
        });
        builder.AddMeter("flowtide.*");
    });

Replace {your connection string} with your application insights connection string. This will then start uploading custom metrics to your Application Insights in Azure Monitor.

Health check export

If you want to publish/export health check information, install the following nuget package:

• AspNetCore.HealthChecks.Publisher.ApplicationInsights

Add the following to your Program.cs:

builder.Services.AddHealthChecks()
    .AddFlowtideCheck()
    .AddApplicationInsightsPublisher("{your connection string}");

Replace {your connection string} with your application insights connection string. You should now see custom events being published to Application Insights with health check information.

Sample

A sample application exist for both setups in github.
