View telemetry with Azure Monitor and third-party tools

Your app is collecting telemetry data, and you now need a more comprehensive way to view it. In this unit, you’ll see how to view telemetry data in many different tools.

Monitor and view telemetry data

A common way to view telemetry data is to use Prometheus and Grafana together. Prometheus is an open-source monitoring system that collects metrics from your cloud-native app. Grafana is an open-source visualization tool that you use to create dashboards to view the metrics collected by Prometheus.

Prometheus

The first step is to add a Prometheus container, and configure it to collect data from each microservice in your app. You then add the Prometheus .NET client library to collect metrics from the app.

OpenTelemetry provides an exporter for Prometheus. You can add this exporter to your app by including the OpenTelemetry.Exporter.Prometheus.AspNetCore NuGet package. This package exports metrics to Prometheus in a format that it can understand. You replace the current console exporter with the Prometheus exporter.

You add the endpoints for all the microservices in your app. For example:

ymlCopy

global:
  scrape_interval: 1s

scrape_configs:
  - job_name: 'products'
    static_configs:
      - targets: ['backend:8080']
  - job_name: 'store'
    static_configs:
      - targets: ['frontend:8080']
