Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Importing JavaScript Object Notation (JSON) Data with Logst

This video tutorial covers the basics of JSON, its structure, and how it integrates with Elasticsearch. It explains the use of the Logstash JSON Filter Plugin to parse JSON data into structured events for Elasticsearch. The tutorial provides a detailed guide on configuring Logstash for JSON parsing, including advanced configurations for filtering and cleaning data. It also addresses handling arrays in JSON by splitting them into individual documents.

• To parse JSON data into structured events

In Logstash configuration, what does the 'start_position' parameter specify?

• The beginning of the file

• The middle of the file

What is the purpose of the 'split' filter in Logstash?

• To encrypt documents

• By using the 'flatten' filter

What is the result of using the 'add_field' option in Logstash?

• It encrypts the document

• It adds new fields to the document

• It removes fields from the document

• It compresses the document

Which Logstash filter is used to remove unnecessary metadata fields?

• Compress

• Split

• Mutate
