TelemetrySrcGen 1.1.4

TelemetrySrcGen

A simple source generator to create the boilerplate code needed to report performance metrics via App Insights.

TelemetrySrcGen lets you define telemetry metrics in the form of simple fields and the source generator creates the methods to send metrics to app insights for you.

Usage

using Microsoft.ApplicationInsights;

[TelemetrySource]
public partial class MyIngestionTelemetry
{
    private TelemetryClient telemetryClient;
    public MyIngestionTelemetry(TelemetryClient telemetryClient)
    {
        this.telemetryClient = telemetryClient;
    }

    [Measurement(MetricKind.Duration)]
    public bool IngestionProcess ;

    [Measurement(MetricKind.Duration)]
    public bool DeliveryTime;

    [Measurement(MetricKind.Counter)]
    public double DataPointsReceived;

    [Measurement(MetricKind.Operation)]
    public bool CallAPI;
    
    [Measurement(MetricKind.Event)]
    public partial void OnPollingSucceeded(IDictionary<string, string> properties = null, IDictionary<string, double> metrics = null); 
}

Will Augment your class with some extra methods to drive App Insights.
