Practical Microservices with Dapr and .NET

By: Davide Bedin

Overview of this book

Over the last decade, there has been a huge shift from heavily coded monolithic applications to finer, self-contained microservices. Dapr is a new, open source project by Microsoft that provides proven techniques and best practices for developing modern applications. It offers platform-agnostic features for running your applications on public cloud, on-premises, and even on edge devices. This book 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 offers ease of implementation while allowing you to work with multiple languages and platforms. You'll also understand how Dapr's runtime, services, 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 to build 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. By the end of this book, you'll be able to write microservices easily using your choice of language or framework 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 Grafana...
