OpenTelemetryUsing

Sample application showing how to write up ASP.NET Core REST API application with OpenTelemetry and export:

• metrics to the Prometheus;
• logs to the Grafana Loki;
• traces to the Grafana Tempo.
• all telemetry to the Azure Application Insights

Three architectural solutions are used:

Solution #1

• The Prometheus scrapes metrics from the application.
• The application pushes logs to Loki.
• The application pushes traces to Tempo.

Solution #2

• The application pushes logs, traces, and metrics to the OpenTelemetry Collector.
• The Prometheus scrapes metrics from the Collector. The collector pushes logs to the Loki and traces to the Tempo.

Solution #3

• The application pushes logs, traces, and metrics to the Azure Application Insights.

The solution was based on an article.
