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.
