Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the Kibana service using systemctl.

Elasticsearch

sudo systemctl [1] kibana.service

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'stop' instead of 'start' will stop the service.

Using 'status' only shows the service status, not start it.

To start the Kibana service, you use systemctl start kibana.service.

Complete the URL to access Kibana on localhost with default port.

Elasticsearch

http://localhost:[1]

Drag options to blanks, or click blank then click option'

A5601

B9200

C8080

D443

Attempts:

3 left

💡 Hint

Common Mistakes

Using 9200 which is Elasticsearch's port.

Using 8080 or 443 which are common web ports but not Kibana's default.

Kibana runs on port 5601 by default, so the URL is http://localhost:5601.

hard

Fix the error in the Kibana configuration file to set the Elasticsearch URL correctly.

Elasticsearch

elasticsearch.hosts: ["[1]"]

Drag options to blanks, or click blank then click option'

Ahttp://localhost:5601

Bhttps://localhost:9200

Chttp://localhost:9200

Dhttps://localhost:5601

Attempts:

3 left

💡 Hint

Common Mistakes

Setting the URL to Kibana's port 5601 instead of Elasticsearch's 9200.

Using https without proper certificates.

The elasticsearch.hosts setting must point to the Elasticsearch server, which runs on port 9200, not Kibana's port 5601.

4fill in blank

hard

Fill both blanks to configure Kibana to listen on all network interfaces and enable the server.

Elasticsearch

server.host: "[1]"
kibana.enabled: [2]

Drag options to blanks, or click blank then click option'

A0.0.0.0

Btrue

Cfalse

D127.0.0.1

Attempts:

3 left

💡 Hint

Common Mistakes

Using 127.0.0.1 limits Kibana to localhost only.

Setting enabled to false disables Kibana.

Setting server.host to 0.0.0.0 makes Kibana listen on all interfaces. Setting kibana.enabled to true enables the server.

5fill in blank

hard

Fill all three blanks to create a basic Kibana index pattern configuration in YAML.

Elasticsearch

index_patterns:
  - [1]
  - [2]
  - [3]

Drag options to blanks, or click blank then click option'

A"logstash-*"

B"metrics-*"

C"filebeat-*"

D"kibana-*"

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'kibana-*' which is not a typical data index pattern.

Forgetting the quotes around patterns.

Common index patterns for Kibana include logstash-*, metrics-*, and filebeat-*. These allow Kibana to find data from different sources.

Practice

1. What is the main requirement before starting Kibana to ensure it works properly?

easy

A. The browser must be Internet Explorer

B. Kibana must be installed on a different server

C. Elasticsearch must be running

D. A database connection must be configured

Solution

1. Step 1: Understand Kibana's dependency

   Kibana is a visualization tool that requires Elasticsearch to provide data.

2. Step 2: Confirm service requirement

   Without Elasticsearch running, Kibana cannot fetch or display data.

3. Final Answer:

   Elasticsearch must be running -> Option C

4. Quick Check:

   Kibana needs Elasticsearch running [OK]

Hint: Remember: Kibana shows data from Elasticsearch only [OK]

Common Mistakes:

• Thinking Kibana works standalone without Elasticsearch
• Confusing Kibana with a database
• Assuming any browser works without checking compatibility

2. Which setting in kibana.yml specifies the Elasticsearch server address?

easy

A. elasticsearch.hosts

B. server.port

C. kibana.index

D. logging.dest

Solution

1. Step 1: Identify configuration purpose

   The kibana.yml file configures Kibana settings including connection details.

2. Step 2: Locate Elasticsearch host setting

   The setting elasticsearch.hosts defines the URL(s) of Elasticsearch nodes Kibana connects to.

3. Final Answer:

   elasticsearch.hosts -> Option A

4. Quick Check:

   Elasticsearch server address = elasticsearch.hosts [OK]

Hint: Look for 'elasticsearch.hosts' in kibana.yml [OK]

Common Mistakes:

• Confusing server.port with Elasticsearch address
• Using kibana.index which is for saved objects
• Mistaking logging.dest for connection settings

3. Given the following kibana.yml snippet:

elasticsearch.hosts: ["http://localhost:9200"]
server.port: 5601

What URL should you open in your browser to access Kibana?

medium

A. http://localhost:9200

B. http://localhost:9200/kibana

C. http://localhost:5601/elasticsearch

D. http://localhost:5601

Solution

1. Step 1: Identify Kibana server port

   The setting server.port: 5601 means Kibana listens on port 5601.

2. Step 2: Determine correct URL

   To access Kibana, open the browser at http://localhost:5601. Port 9200 is for Elasticsearch, not Kibana.

3. Final Answer:

   http://localhost:5601 -> Option D

4. Quick Check:

   Kibana URL uses server.port = 5601 [OK]

Hint: Kibana runs on server.port, default 5601 [OK]

Common Mistakes:

• Opening Elasticsearch port 9200 instead of Kibana port
• Appending /kibana or /elasticsearch incorrectly
• Confusing ports between services

4. You started Kibana but get a connection error. Which of these is the most likely cause?

medium

A. Elasticsearch service is not running

B. Kibana is running on port 9200

C. Browser cache is full

D. Kibana.yml file is missing

Solution

1. Step 1: Understand connection error cause

   Kibana depends on Elasticsearch; if Elasticsearch is down, Kibana cannot connect.

2. Step 2: Evaluate other options

   Kibana does not run on port 9200 (Elasticsearch default). Browser cache or missing config file usually cause different errors.

3. Final Answer:

   Elasticsearch service is not running -> Option A

4. Quick Check:

   Connection error = Elasticsearch down [OK]

Hint: Check Elasticsearch service status first [OK]

Common Mistakes:

• Assuming Kibana runs on Elasticsearch port
• Blaming browser cache for connection errors
• Ignoring Elasticsearch service status

5. You want to connect Kibana to a remote Elasticsearch server at http://192.168.1.100:9200. Which is the correct elasticsearch.hosts setting in kibana.yml?

hard

A. elasticsearch.hosts: ["http://localhost:9200"]

B. elasticsearch.hosts: ["http://192.168.1.100:9200"]

C. elasticsearch.hosts: "192.168.1.100:5601"

D. elasticsearch.hosts: ["https://192.168.1.100:5601"]

Solution

1. Step 1: Identify remote Elasticsearch URL

   The remote server address is http://192.168.1.100:9200, which is the default Elasticsearch port.

2. Step 2: Set elasticsearch.hosts correctly

   The setting must be a list with the full URL including protocol and port: ["http://192.168.1.100:9200"].

3. Step 3: Eliminate incorrect options

   elasticsearch.hosts: ["http://localhost:9200"] points to localhost, not remote. Options C and D use wrong ports or protocols for Elasticsearch.

4. Final Answer:

   elasticsearch.hosts: ["http://192.168.1.100:9200"] -> Option B

5. Quick Check:

   Remote Elasticsearch URL in elasticsearch.hosts list [OK]

Hint: Use full URL with http and port 9200 in elasticsearch.hosts [OK]

Common Mistakes:

• Using localhost instead of remote IP
• Omitting protocol (http://)
• Using wrong port like 5601 for Elasticsearch
