Grafana Tutorial

Grafana is an open-source data visualization and analysis tool which allows us to view our data in the form of beautiful graphs.

What is Grafana?

  • Grafana is an open-source data visualization and analysis tool designed by Torkel Odegaard in January 2014.
  • It enables us to create a dashboard for collecting, processing, storing, and analyzing data from various different sources.
  • It allows us to query, visualize, alert on, and understand our metrics without worrying about the location where it is stored on the memory.
  • It includes a variety of visualization option that helps us to understand our data, beautifully.
  • Grafana is written in Go and Node.js LTS language with a strong API (Application Programming Interface).

What is Grafana Dashboard?

Grafana Dashboard is used to pull data from various data sources such as Prometheus, Influx DB, Graphite, ElasticSearch, MySQL, PostgreSQL, CloudWatch, Microsoft SQL Server, and many more.

A Grafana Dashboard contains various visualization options such as heat maps, geo maps, histograms, tables, free text panels, and different types of charts & graphs to study and understand business data easily.

In Grafana, we create the following types of Grafana Dashboard:

  • Dynamic Dashboard
  • Production Dashboard
  • VMware VMs
  • Cisco switch RV 325 Dashboard
  • MariaDB Dashboard
  • Testing dynamic Dashboard

Why Grafana?

There are the following reasons to use Grafana –

1. Easy virtualization

Grafana provides the best virtualization technique by adding multiple graphs to a single visualization panel.

2. Drag and drop panels

Grafana uses drag and drop panels to insert images, videos, tables, and graphs on the Grafana dashboard.

3. Flexible to use               

Grafana is flexible to use because it can combine with influx Data.

4. Support 30+ Data Sources

Grafana supports more than 30 data sources to bring our data together for a better context. Grafana mainly uses various databases like Azure Monitor, Elasticsearch, Loki, Microsoft SQL Server (MSSQL), OpenTSDB, and PostgreSQL. Grafana provides a customized query editor and specifies a syntax for each data source.

5. Open-source

Grafana is an open-source platform because we don’t need any license and pay any charge to use the Grafana platform.

6. Multi-platform support

Grafana supports multi-platform so that we can install Grafana in any platform like Windows, Linux, Mac, Docker container, and ARM.

History of Grafana

Before Grafana, most of the companies use the Kibana. Kibana helps us to build a dashboard by writing the JSON documents. The disadvantage of Kibana is that the editing panel was a little tricky.

To remove the issues related to Kibana, Grafana was introduced.

Grafana v1 (2014)

  • Grafana v1 helps us to make editing easier.
  • It provides a full-screen edit mode with the visible panel taking views and options.
  • It also helps us to make queries easier and more understandable.

Grafana v2 (2015)

  • Grafana v2 introduced the backend application, which was written in the Go programming language.
  • It helps us to save the dashboard without using ElasticSearch.
  • It contains a side menu with data source that we can add through the UI.
  • It also allows us to go into a separate server admin section.

Grafana v3 & v4 (2016)

  • Grafana v3 introduced the plugin system and also add official support for panel plugins.
  • grafana.net was launched, which had a plugin and dashboard repository.
  • Grafana v4 made some small style changes.

Grafana v5 (2018)

  • Grafana v5 solves the problem related to rows (add and edit rows), by switching to a new grid system.
  • It strongly focused on backward compatibility when we move to the dashboards and visualizations.
  • Increase the security to ensure users that their dashboards and graphs are safe and remain the same. 

Grafana v6 (2019)

  • It enables us to switch virtualization without removing the panel.
  • Grafana v6 mainly focused on UX work.

Features of Grafana

The most important features of Grafana are listed below:

1. Plugins Platform

Grafana provides an advanced platform to users for easier, faster, and most efficiently create new high-quality plugins.

2. Transformation

Transformation is the most important feature of Grafana that allows us to transform non-time series data into tables within seconds without any additional overhead.

3. Dynamic Dashboards

Grafana helps us to create a dynamic and reusable dashboard with good looking templates that appear at the top of the dashboard.

4. Authentication

Grafana supports authentication techniques like LDAP and Google Auth to map users to the organization.

5. Explore Metrics and Logs

In Grafana, we can explore our data metrics through ad-hoc queries. We can also split-view using different time range and data range.

6. Alerting

Grafana helps us to continuously evaluate and send alert notification to a number of different notifiers, including systems such as Slack, VictorOps, OPsGenie, SMS, email, and PagerDuty.

7. Annotations

Annotations are useful for correlating data if something went to wrong.

8. Mixed Data Sources

Grafana supports various storage backends for data sources such as AWS CloudWatch, Azure Monitor, Elasticsearch, Loki, Microsoft SQL Server (MSSQL), OpenTSDB, PostgreSQL, and Stackdrier.

9. Beautiful Dashboard

Grafana contains a well-designed dashboard with beautiful Graphs, Text, Alert messages, tables, clock, Logs, plugin lists, and more.

10. Big community

Grafana community has more than 600 developers all over the world. Its community includes large organizations such as VMware, Paypal, AWS, RedHat, and more.
