Creating Your Own Dashboard with Elasticsearch

In our contemporary data-centric landscape, the volume of data generated is staggering. Yet, interpreting raw data often poses significant challenges.

Dashboards have surged in popularity as they effectively showcase data, enabling users to quickly assess key performance indicators and delve into more intricate information when needed.

But, what exactly is a dashboard? How do we create one? What platforms are most widely used?

Let’s explore!

Understanding the Dashboard Concept

A dashboard serves as a visual interface that presents crucial data in an easily digestible manner. Its primary goal is to assist users in swiftly monitoring and analyzing complex datasets, recognizing trends, and making well-informed decisions based on the insights derived.

Dashboards can either be static or dynamic, depending on whether the data updates during the dashboard's lifespan:

• Static Dashboards: Typically used for historical analysis or reporting on specific metrics.
• Dynamic Dashboards: Provide real-time updates about a particular topic.

So is it merely about visualizing data? Not quite! A crucial step in building a dashboard must not be overlooked.

Any guesses?

Correct, every dashboard requires a data source!

It’s essential to ensure that the data intended for visualization actually reaches the dashboard; this is where the concept of *data ingestion* becomes relevant.

Data Ingestion

Data ingestion encompasses the collection, importation, and processing of data from requisite sources, preparing it for analysis and visualization.

Establishing a robust pipeline for sending data to the visualization platform is vital to prevent frequent crashes of your dashboard, thereby enhancing its resilience to data fluctuations.

Some platforms integrate both data storage and dashboard creation tools, facilitating real-time visualization generation from that data. Elasticsearch exemplifies such a platform, acting as both a Data Store and a Data Visualization Platform.

Choosing the right platform is your decision! However, I must admit that I recommend Elasticsearch due to its flexibility. :)

Data Visualization Platforms

The ideal platform for dashboard creation hinges on the dashboard type and the intended data source. Here are a few examples:

• For static dashboards or infrequently updated data, options like Tableau, Power BI, or Google Data Studio are excellent choices.
• When higher update frequency or live data is required, platforms such as Elasticsearch, Kibana, or Splunk are commonly utilized.

These latter platforms are particularly favored for live data dashboards, as they assist in collecting, analyzing, and visualizing real-time data from diverse sources. Additionally, they often include built-in features for creating visualizations and alerts based on real-time data.

Proficiency in these platforms is crucial in the data realm, as they enable the creation of data visualizations in just a few steps!

Let’s delve into the principles behind Elasticsearch, so you can incorporate this platform into your data toolkit.

Getting Started with Elasticsearch

Elasticsearch is a distributed, scalable, and highly available analytics engine designed for efficient data storage, retrieval, and analysis of large datasets. It employs a distributed storage system to index data, facilitating rapid and efficient data retrieval.

It accommodates various data types and formats while offering robust search functionalities such as full-text search and faceted search, among others.

How to Utilize Elasticsearch

There are multiple ways to use Elasticsearch for free:

• Self-Hosting: Download Elasticsearch software from the official site and install it on your machine or server. This option is entirely free, though some technical know-how is necessary for setup and maintenance.
• Cloud Services: Numerous cloud providers, including Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure, offer managed Elasticsearch services. These typically feature a free tier with limited resources for testing or developing applications.
• Elastic Cloud: Elastic, the company behind Elasticsearch, also provides a managed service known as Elastic Cloud. They offer a free 14-day trial for testing, after which you can select a pricing plan that fits your requirements.

Basic Concepts

Here are some foundational concepts in Elasticsearch to help you get started quickly:

#1. Index An index resembles a table in SQL. It serves as a logical namespace grouping a set of entries together.

You might visualize it as if rows from various csv files were directly stored in Elasticsearch, with the index serving to group together all rows belonging to the same table.

#2. Document A document represents a basic unit of information in Elasticsearch.

It mirrors the concept of a row in a traditional database table. Each document possesses a unique identifier (ID) for updating the corresponding information. Documents consist of fields, which are essentially key-value pairs storing the necessary information.

#3. Query A query facilitates searching for specific data within Elasticsearch, allowing you to specify search criteria and retrieve matching documents.

Elasticsearch supports a diverse range of queries, including term queries, match queries, range queries, bool queries, and more. Using the query function, you can group documents sharing common properties.

#4. Aggregation Aggregations in Elasticsearch allow for calculations on data and summarizing results.

They can be utilized intuitively to produce statistical summaries, compute histograms, and group data by terms, among other functions. Aggregations are especially beneficial when constructing dashboard visualizations.

Concepts are essential, but where can we apply them?

Elasticsearch Interface

Finally, it’s beneficial to familiarize yourself with key tabs in the Elasticsearch web interface:

• The Discover tab for visualizing raw ingested data.
• The Dashboard tab for further representation through visualizations.

Both tabs are located under the Analytics section in the left-hand navigation panel:

Discover The Discover tab offers a user-friendly interface for data exploration and searching within Elasticsearch. It enables users to easily visualize and query their data. Key features include:

#1. Data Exploration: Browse through available fields and documents in your indices with a table view that can be sorted and filtered to locate desired information.

#2. Search: Utilize the search bar to query specific data using the query syntax.

#3. Time Range: Select a specific time range for your search, which is particularly useful for time-series data, using a slider or by specifying start and end times.

Overall, the Discover tab in Elasticsearch is a powerful tool for exploring and analyzing data stored in Elasticsearch indices, providing a user-friendly interface for rapid data searching and exploration, making it easier to derive insights and make informed choices.

Dashboard The Dashboard tab in Elasticsearch Cloud enables you to create and manage visual dashboards for real-time data monitoring and analysis. Here are the fundamental steps for navigating this tab:

#1. Create a New Dashboard: Click on the Create New Dashboard button to initiate a new dashboard.

#2. Create Visualizations: After creating a new dashboard, you can add multiple visualizations to it. Various visualization types are available, including bar charts, line charts, and tables.

#3. Customize Your Visualizations: This can be done by selecting the data source, applying filters, and specifying chart or graph types. The best part? It supports drag-and-drop!

#4. Organize and Personalize Your Dashboard: You can also adjust the layout by rearranging visualizations, changing their size and orientation, and adding custom text.

#5. Save and Share Your Dashboard: Once complete, you can save and share your dashboard with other users. Elasticsearch Dashboards also allow exploration of data through a point-and-click interface.

#6. Advanced Options: Set up alerts and notifications to receive updates when specific conditions are met. We will delve into this in a future article!

That’s it! With the Dashboard tab in Elasticsearch Cloud, you can create tailored visualizations and interactive dashboards that facilitate real-time data monitoring and analysis.

Given the vast amounts of information generated today, having tools to help locate a needle in a haystack is crucial. In essence, transforming raw data into actionable insights.

Elasticsearch is a comprehensive tool that can guide you through the necessary steps to bring your Dashboard to life! And remember, it’s an ideal platform for all types of dashboards, especially when dealing with time-series or live data!

I hope you’re convinced to give Elasticsearch a try! :)
