Introduction

ELK stack included three component:

• ElasticSearch

• Logstash

• Kibana

Additional software packages called Beats are a newer addition. These are smaller data collection applications, specialized for individual tasks. There are many different Beats applications for different purposes. For example, Filebeat is used to collect log files, while Packetbeat is used to analyze network traffic.

Due to the ELK acronym quickly growing, the Elastic Stack became the more satisfactory and scalable option for the name. However, ELK and Elastic Stack are used interchangeably.

Why Is Log Management Important?

Without centralised log management organisations are vulnerable as a result of not being able to pinpoint log events that signify potential security breaches, attempted hacks, abuse of privileges and errors.

Whilst many professionals that handle data in a variety of formats will find log management and its subsequent analysis useful, the leading roles that commonly find themselves conducting this task tend to be in one of the following departments: DevOps, Development, Data Analyst, System Administration, Cybersecurity and Business Analysts.

The global popularity of Log management is growing steadily and consistently with the most interest being expressed in this solution by companies operating in the US (46%), India (10%), the UK (6%), Vietnam (5%) and Indonesia (4%).
