What is Grafana?

Grafana is a database that is responsible for monitoring and analysis. It also ensures that users can build dashboard visualizations related to the essential measures organizations need for analysis. It also involves a community of enthusiasts responsible for sharing recyclable dashboards.

A distinctive attribute of Grafana is that it can connect with almost all possible data sources available in recent times, including third-party data gathering and filtering tools, databases, and more. This flexibility is useful for various users, thanks to its open-source nature. For this reason, users can write plugins for almost any data source and make them available to others. In addition, Grafana can be deployed on-premises, particularly if sensitive data is involved.

Another top feature of this tool is its intuitive dashboards, which can display data in the form of charts and graphs, making it easy to understand. The dashboard often comes with numerous panels on a grid. Each of these panels is capable of displaying different types of data. There are also possible visualization options for these panels, which include heat maps, graphs, charts, histograms, and more.

Advantages of Grafana

Grafana ensures that users can visualize and query relevant data irrespective of where it is stored. This tool offers many benefits:

  • Grafana offers a unified view and is best known for connecting with different sources to analyze users’ data while presenting them through dashboards. With Grafana, users can get a simple view of the results.
  • Another great advantage of Grafana is its ability to break down data silos. A huge problem for traditional and disparate networks is the presence of data silos, making it hard for users to get the right idea of their operations’ states. Grafana is capable of breaking down these data silos. After all, it can effortlessly connect with multiple data sources.
  • Data Accessibility is another top benefit Grafana offers. After breaking down data silos, authorized users can access any available data. Grafana ensures that no data is restricted because of infrastructure issues. Grafana can also ensure that teams with data can be empowered at the right time to make informed and essential decisions.
  • Grafana is also quite versatile. With Grafana, users can connect.

How to Install Grafana on Windows

On the Windows platform, Grafana can be installed either through a Standalone library file or a Windows installer package.

Let us consider installing Grafana using Windows Installer.

After pressing “Download the Installer,” open and Execute

To run Grafana, open the browser and navigate the Grafana port, and adopt the following instructions:

Install the Grafana

Grafana can be installed on various operating systems. You will find some requirements for software and hardware as follows:

Hardware Requirements

  • Server-Side Rendering of the Images
  • The minimum required memory of 255MB
  • Data Source Proxy

Software Requirements

  • A database for storing configurations. Grafana supports SQLite, MySQL, PostgreSQL

The next step is to log in; logging into Grafana for the first time requires the following:

  • Open the web browser and visit “http://localhost:3000/”. It is worth pointing out that Grafana listens to a default HTTP port: 3000. This is so until the data port is configured.
  • On the login page, input the word “admin” for username and password.
  • Click on Log in. Then, you can proceed to change the password.

How to Install Grafana on MacOS

You can start this by installing Homebrew, which can help install the recent version of Grafana.

On the homepage of Homebrew, search for Grafana. Then, open the terminal and enter. You will find the listing of the latest version of Grafana.

brew update

brew install grafana

Brew page downloads and goes into the following files

/usr/local/cellar/grafana/[version] (Homebrew v2)

/opt/homebrew/cellar/grafana/[version] (Homebrew v3)

After this, the following command can help you start Grafana:

brew services start grafana

How to Install Standalone MacOS Libraries

Certain steps must be followed to install the latest version of Grafana without the use of Homebrew. First, visit the Grafana Download Page.

Then, select the Grafana version to install. By default, the latest version is chosen.

Then, choose the Edition. Two editions to consider are explained as follows:

  • Enterprise Users find this the most appropriate version to make use of. The enterprise edition has functionality that shares some similarities with the open-source edition (which will be explained next). Yet, several features can be unlocked with licenses.
  • Open Source The features of this edition are not as vast as the enterprise edition. Users may need to download the latter to enjoy these features.

Then, open the terminal and use the curl command to download the binary file. The following command displays Grafana 7.1.5 version:

Curl -0 https://d1.grafana.com/oss/release/grafana-7.1.5.darwin-amd64.tar.gz

Then, input the “gz” file while copying files to a preferred location.

The next step is to start the Grafana service. To do this, open the directory and execute the command:

./bin/grafana-server web

How to Configure Our Data Source

The first step towards building a Grafana dashboard is configuring the data source. Various data sources are supported by Grafana, including traditional data sources, such as MySQL, the log aggregation platforms, and the AWS CloudWatch. A collection of logs or a database can be used as the data source.

The Grafana user must be added to the database. In the MySQL database, the database administrator will execute the following for adding the read-only user with the name “GrafanaReader” to our database “CD” for table “Artist”.

Now, when it comes to adding the link from our database to the Grafana, go back to the Grafana interface.

The first that will appear is “Create our first data source” Complete the web form with our connection details. Then, you can complete the web form with connection details. If the local MySQL database – which is running on the localhost on port 3306 for database “CD” – is being adopted, then it is not a bad idea to leave the rest of the fields as default.

Then, press Save and Test. Once everything is configured correctly, a green box with the message “Database Connection OK” will show up

Creating Dashboards

What the Grafana dashboard does is that it is capable of bringing the data together in an organized and efficient manner. With a dashboard, users can enjoy a detailed view of the data while also tracking the measures by adopting different visualizations. Dashboards come with panels that describe a part of what a user wishes to convey.

Freeware is another top feature of Grafana dashboards. With this, users can understand the measure of data by adopting queries, alerts, and detailed visualization. With Grafana, it is also possible to share dashboards with others. This ensures that users can analyze data at once. This ensures that more personalization and power are supported. However, this depends on how good the coding is. Despite this, there is no need for any comprehensive coding knowledge to create a functioning dashboard.

Grafana Dashboard Templates

Grafana Dashboard templating can be adopted to make support a more responsive dashboard. It is also possible to build dashboard template variables, which can be used in the Grafana dashboard.

The panel consists of a query and a visualization. The query specifies the kind of data that must be displayed, while the visualization talks about the data that can be shown. You can follow the steps below:

  • In the sidebar, hover the cursor on the “create” icon and then click on “Download”.
  • Then, click on “Add New Panel”.
  • In Query Editor of the graph, type the query from earlier, and next click “Shift+Enter”:
  • To rename the time series in the time legend, input the word “route” in the “Legend” field. Graph legend updates when we press outside the field.
  • In the Panel editor on the right, in Settings, change the panel title to the term “Traffic”.
  • Click the “Apply” icon in the top-right corner. This will save the panel while reverting to the dashboard view.
  • Then, click the icon, “Save Dashboard” found at the top of the dashboard for saving the dashboard.
  • Then input the name in the “New Name” field and click “save”.

Building a Panel Plugin

Panels represent constituent elements available in Grafana. With these panels, users can visualize data in multiple ways. Even though Grafana is associated with various kinds of in-built panels, another panel can be built to support these visualizations.

Configure Our Environment to Develop the Plugins

Before plugins are built, the environment for developing plugins must be set up. To discover plugins, Grafana is capable of scanning the plugin directory. Following these steps:

  • Create a “Grafana -plugins” directory in the chosen location
  • Figure out the “plugins” property in the Grafana configuration file. Then, you can set the “plugins” property to the path of the required “grafana-plugin” directory.

Plugins = “/path/to/grafana-plugins”

  • Then, to load the new configuration, restart the Grafana if it is already working.

How To Create a New Plugin

Creating a new plugin requires using “Grafana-toolkit,” the CLI application that streamlines the Grafana plugin development to concentrate on code. Follow these steps:

  • In Plugin Directory, you can create the plugin from the template by inputting the “plugin: create” command:

npx @grafana/toolkit plugin:create my-plugin

  • Change the directory:

cd my-plugin

  • Then, download the required dependencies:

yarn install

  • Develop the plugin

yarn dev

  • Then, restart the Grafana server for Grafana to figure out the plugin.
  • Ensure that your plugin exists.

Grafana generally logs anytime it finds a plugin. It relies on the right query language for the data source. There are more than 26 queries for a panel that can be supported on Grafana. This could include InfluxQL, Prometheus SQL, PromQL, Elasticsearch, PostgreSQL’s SQL variant, and more.

Prometheus Grafana

The combination of Grafana and Prometheus is the right tool combination many users adopt for executing the data visualization environment. Users can make the most of Grafana Dashboards to visualize the data as the backend gets controlled by Prometheus. While Prometheus is also designed with data visualization features, Grafana can also be used for visualizing the data. With Prometheus, it is possible to store the time series data.

Conclusion

The use of Grafana supports database monitoring and analysis. With it, users can easily build dashboard visualizations that relate to the essential measures that must be analyzed. There is also a reliable community of enthusiasts willing to share recyclable dashboards. Grafana is easy to install and configure. By following the processes explained above, users can get a top experience.
