By: Eric Salituro

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.

Structuring data fields in the Table panel

Our last panel is one of the least graphically visual options of the panels you will encounter in Grafana. The Table panel provides a spreadsheet-like data grid that is useful if you want to see the rows of actual data, along with any aggregations. When rolling up your data series into an aggregation, the Table panel is much more useful than the Graph panel legend. It also gives you the capability to sort any of its columns with a single click. The number of rows can be set to give you either a fixed window of data or a scrolling list.

Comparing aggregations

To give you an idea of how the Table panel compares to the Graph panel legend, let's create a panel and have it display a set of common aggregations. Create a new panel and select a table from Choose Visualization. Enter these parameters for the Query tab:

  • Query: InfluxDB Weather
  • SELECT: default temperature
  • FROM: field ...
