Elasticsearch 7 and Elastic Stack - In Depth and Hands On! - Section 7 Introduction

The video tutorial explains how to publish server logs into an Elasticsearch cluster and addresses the limitations of the current architecture. It introduces Beats, a lightweight utility in the Elastic Stack, which helps overcome these limitations by acting as an intermediary between web servers and Logstash. The tutorial emphasizes the ease of setting up and using Beats, providing a practical understanding of its integration with Logstash and Elasticsearch.

What is a potential issue with directly publishing server logs to an Elasticsearch cluster?

• Elasticsearch cannot handle large volumes of data.

• Logstash can become backed up without an intermediate layer.

• Logs may be lost during transmission.

• Server logs are not compatible with Elasticsearch.

What is the primary function of Beats in the Elastic Stack?

• To act as a lightweight utility for publishing log data.

• To store data permanently.

• To replace Elasticsearch in the stack.

• To provide a user interface for Logstash.

How does Beats help in managing log data?

• By compressing log data to save space.

• By encrypting log data for security.

• By providing a buffer through a separate Logstash cluster.

• By storing logs directly in Elasticsearch.

What is a key benefit of using Beats for log management?

• It requires no additional hardware.

• It is difficult to set up but offers high security.

• It is lightweight and easy to set up and use.

• It automatically scales with server load.

What will make the concepts of using Beats clearer?

• Watching a different tutorial.

• Attending a workshop.

• Using it together in practice.

• Reading more documentation.
