Practical Microservices with Dapr and .NET - Second Edition

By: Davide Bedin

Overview of this book

This second edition will help you get to grips with microservice architectures and how to manage application complexities with Dapr in no time. You'll understand how Dapr simplifies development while allowing you to work with multiple languages and platforms. Following a C# sample, you'll understand how Dapr's runtime, building blocks, and software development kits (SDKs) help you to simplify the creation of resilient and portable microservices. Dapr provides an event-driven runtime that supports the essential features you need for building microservices, including service invocation, state management, and publish/subscribe messaging. You'll explore all of those in addition to various other advanced features with this practical guide to learning Dapr. With a focus on deploying the Dapr sample application to an Azure Kubernetes Service cluster and to the Azure Container Apps serverless platform, you’ll see how to expose the Dapr application with NGINX, YARP, and Azure API Management. By the end of this book, you'll be able to write microservices easily by implementing industry best practices to solve problems related to distributed systems.

Analyzing metrics with Prometheus and Grafana

Prometheus is an open source system and monitoring toolkit, a project with a long history that started in 2012 and is now part of the CNCF.

In our scenario, we will use Prometheus to scrape the metrics exposed by all Dapr Pods and store them as time series. This will act as the data source for the Grafana dashboards.

Grafana is an open source visualization and analytics tool. We will use it to examine the Dapr metrics by importing the dashboard templates released by the Dapr project as assets from https://github.com/dapr/dapr/releases/.

These are the steps we will follow:

  1. Installing Prometheus
  2. Installing Grafana
  3. Importing dashboards

Let’s start by installing the Prometheus service components.

Installing Prometheus

As described in the Dapr documentation, available at https://docs.dapr.io/operations/monitoring/metrics/prometheus/, we should first create a namespace to be used by Prometheus and...
