Overview of this book

Grafana is an open-source analytical platform used to analyze and monitoring time-series data. This beginner's guide will help you get to grips with Grafana's new features for querying, visualizing, and exploring metrics and logs no matter where they are stored. The book begins by showing you how to install and set up the Grafana server. You'll explore the working mechanism of various components of the Grafana interface along with its security features, and learn how to visualize and monitor data using, InfluxDB, Prometheus, Logstash, and Elasticsearch. This Grafana book covers the advanced features of the Graph panel and shows you how Stat, Table, Bar Gauge, and Text are used. You'll build dynamic dashboards to perform end-to-end analytics and label and organize dashboards into folders to make them easier to find. As you progress, the book delves into the administrative aspects of Grafana by creating alerts, setting permissions for teams, and implementing user authentication. Along with exploring Grafana's multi-cloud monitoring support, you'll also learn about Grafana Loki, which is a backend logger for users running Prometheus and Kubernetes. By the end of this book, you'll have gained all the knowledge you need to start building interactive dashboards.

Configuring a Microsoft Azure Monitor data source

The next stop in our tour of the big cloud providers takes us to Microsoft Azure. The Azure Monitor data source supports four different services:

  • Azure Monitor
  • Azure Log Analytics
  • Application Insights
  • Application Insights Analytics

Fortunately, you can configure Azure to allow the data source to access all four services.

As you may recall from Chapter 13,Authentication with External Services, in order to generate OAuth2 Client IDs and Secrets, we needed to register our Grafana server as an application with the cloud service. The process is very similar for Microsoft Azure:

  1. Copy the Tenant ID from Active Directory.
  2. Register our Grafana application and copy the Client ID and Secret.
  3. Associate the application with a Subscription ID.
  4. Generate an API key for Applications Insights.
  5. Create...
