Audio Data Visualization/Analytics Using Kibana

Introduction

Kibana is an open source analytics and visualization platform designed to work with Elasticsearch. Kibana can be used to search, view, and interact with data stored in Elasticsearch indices. We can easily perform advanced data analysis and visualize our data in a variety of charts, tables, and maps format.

Kibana makes it easy to understand large volumes of data. Its simple, browser-based interface enables us to quickly create and share dynamic dashboards that display changes to Elasticsearch queries in real time.

We can install Kibana and start exploring our Elasticsearch indices in minutes without any code, or any additional infrastructure required.

Getting Kibana up

Requirements:

  • Elasticsearch 2.3 or later
  • A modern web browser
  • Information about our Elasticsearch installation:
    • URL of the Elasticsearch instance we want to connect to.
    • Which Elasticsearch indices we want to search.

Install and start Kibana

Installing kibana with apt-get

  1. Download and install the Public Signing Key:

    wget -qO - https://packages.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -

  2. Add the repository definition to your /etc/apt/sources.list.d/kibana.list file:

    echo "deb http://packages.elastic.co/kibana/4.5/debian stable main" | sudo tee -a /etc/apt/sources.list

  3. Run apt-get update and the repository is ready for use. Install Kibana with the following command:

    sudo apt-get update && sudo apt-get install kibana

  4. Configure Kibana to automatically start during bootup. If your distribution is using the System V version of init, run the following command:

    sudo update-rc.d kibana defaults 95 10

  5. start kibana

    sudo service kibana start

That’s it! Kibana is now running on port 5601. You can access the kibana UI by pointing your browser to:

http://localhost:5601

Configuring an index pattern

remove check from Index contains time-based events and put Index name or pattern (as used in elasticsearch) and start.

Now, we are in position to visualize and analyze data stored at that index.

Something which we can do is:

  • Search and browse your data interactively from the Discover page.
  • Chart and map your data from the Visualize page.
  • Create and view custom dashboards from the Dashboard page.
