Kibana setup and connection in Elasticsearch - Mini Project: Build & Apply

Kibana Setup and Connection

📖 Scenario: You are setting up Kibana to visualize data stored in Elasticsearch. Kibana needs to connect to your Elasticsearch cluster to fetch and display data.

🎯 Goal: Set up a basic Kibana configuration file to connect to a local Elasticsearch instance and verify the connection by checking the cluster health.

📋 What You'll Learn

Create a Kibana configuration file with the Elasticsearch URL

Set a timeout value for the connection

Write a command or script to check the Elasticsearch cluster health

Print the cluster health status to confirm connection

💡 Why This Matters

🌍 Real World

Kibana is a popular tool to visualize and analyze data stored in Elasticsearch. Setting up the connection correctly is the first step to use Kibana dashboards.

💼 Career

Many jobs in data analysis, DevOps, and backend development require configuring and troubleshooting Elasticsearch and Kibana connections.

1

Create Kibana configuration with Elasticsearch URL

Create a file named kibana.yml and add the line elasticsearch.hosts: ["http://localhost:9200"] to specify the Elasticsearch URL.

Elasticsearch

# Create kibana.yml with elasticsearch.hosts setting
# Your code here

Need a hint?

This line tells Kibana where to find Elasticsearch. Use the exact URL http://localhost:9200.

2

Add connection timeout setting

In the kibana.yml file, add the line elasticsearch.requestTimeout: 30000 to set the connection timeout to 30 seconds.

Elasticsearch

elasticsearch.hosts: ["http://localhost:9200"]
# Add elasticsearch.requestTimeout setting below
# Your code here

Need a hint?

This setting controls how long Kibana waits for a response from Elasticsearch.

3

Check Elasticsearch cluster health

Write a shell command to check the Elasticsearch cluster health by sending a GET request to http://localhost:9200/_cluster/health using curl.

Elasticsearch

elasticsearch.hosts: ["http://localhost:9200"]
elasticsearch.requestTimeout: 30000
# Write curl command to check cluster health
# Your code here

Need a hint?

The -s option makes curl silent except for the output.

4

Print cluster health status

Use the curl command output and print only the status field from the JSON response using jq. The command should be curl -s http://localhost:9200/_cluster/health | jq -r '.status'.

Elasticsearch

elasticsearch.hosts: ["http://localhost:9200"]
elasticsearch.requestTimeout: 30000
curl -s http://localhost:9200/_cluster/health | jq -r '.status'  # Your code here

Need a hint?

This command prints the cluster health status like green, yellow, or red.
