Overview of this book

Grafana is a powerful open source software that helps you to visualize and analyze data gathered from various sources. It allows you to share valuable information through unclouded dashboards, run analytics, and send notifications. Building IoT Visualizations Using Grafana offers how-to procedures, useful resources, and advice that will help you to implement IoT solutions with confidence. You’ll begin by installing and configuring Grafana according to your needs. Next, you’ll acquire the skills needed to implement your own IoT system using communication brokers, databases, and metric management systems, as well as integrate everything with Grafana. You’ll learn to collect data from IoT devices and store it in databases, as well as discover how to connect databases to Grafana, make queries, and build insightful dashboards. Finally, the book will help you implement analytics for visualizing data, performing automation, and delivering notifications. By the end of this Grafana book, you’ll be able to build insightful dashboards, perform analytics, and deliver notifications that apply to IoT and IT systems.

Connecting alerts and notifications

So far, you have learned how to build alerts and manage them. Also, you have seen how to create contact points to deliver alert notifications to the users.

In this section, you will learn how to connect both parts. So, you will be able to send notifications of specific alerts, in a specific way, to specific users. You can do this in Grafana using notification policies.

By using notification policies, you can define how the alerts will be routed to the contact points. These policies are built on a tree structure, where each policy can have one or more child policies.

With the exception of the root policy, all the policies can match specific alert labels. Every time an alert occurs, it is evaluated by the root policy first, and then by each child policy. If you enable the Continue matching subsequent sibling nodes option for a policy, the evaluation will continue even after one or more matches.

Policies have a hierarchical behavior. Any...
