TelemetrySrcGen 1.1.2

TelemetrySrcGen

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

The aim of the thing is to let you define what you need in the form of some fields and let the source generator create the methods to drive 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.
