Track Spotify Metrics: Use Docker with Prometheus and Grafana

After adding .Net Aspire Service Defaults and .Net Aspire AppHost to WinampToSpotify project I have added following code to run Prometheus and Grafana on local with Docker Desktop. Docker Desktop is required to run to start code below. // Prometheus container scraping the app // Grafana container using Prometheus as data source prometheus.yml is the default prometheus configuration I created OpenTelemetryLib project and created ServiceCollection extension method which configures OTEL export endpoints. OpenTelemetry, OpenTelemetry.Exporter.Console, OpenTelemetry.Exporter.OpenTelemetryProtocol, OpenTelemetry.Exporter.Prometheus.HttpListener, OpenTelemetry.Instrumentation.Process nuget packages installed. Spotify metrics class created to register spotify service related metrics. I started to keep track number of total tracks added by each folder. WinamptoSpotifyMetricsManager class helps to register metrics which uses IMeterFactory to register. winamptospotifyweb.spotifyservice.totaltracksadded metric exported to Aspire Dashboard, Prometheus and Grafana. Code changes can be found dotnet aspire added and opentelemetry and metrics added commits. Templates let you quickly answer FAQs or store snippets for re-use.
