What is Splunk?

Splunk is a widely popular software platform that is employed for searching, visualizing, analyzing, and monitoring machine-generated data in real-time. It performs a lot of tasks like indexing, correlating, and capturing the real-time data in a searchable container to ultimately help in producing dashboards, alerts, visualizations, and graphs. 

It can be seen as a data mining tool but for big data applications. And it is so famous because no database is necessary for storing its data. Why? Because it extensively uses its indexes for storing the data.

Features of Splunk

Splunk is so famous everywhere because of the numerous features it has to boast about. Here are a few of the top Splunk features:

  • It facilitates building real-time data apps.
  • Helps improve performance by troubleshooting any condition.
  • Empowers users with its analysis, visualization, and search capabilities.
  • Generates faster ROI.
  • Fastens the testing and development phase.
  • Accepts data in all formats, such as JSON, CSV, etc.
  • Enables real-time architecture and agile figures documentation.

Splunk Architecture

The Splunk architecture is composed of three key components.

1. Splunk Forwarder

The job of Splunk Forwarder is to collect real-time data so that the user can implement real-time data analysis. The entire log's data is collected by the Splunk Forwarder and is sent to the indexer. There are two main Splunk Forwarders -

  • Splunk Forwarder
  • Search Head
  • Splunk Indexer

2. Search Head

Splunk Search Head is a graphical user interface that allows the user to perform a plethora of operations as per their requirements. This stage allows easy interaction with Splunk and consequent performance of search and query operations on the entire Splunk data.

3. Splunk Indexer

The Splunk Indexer is employed for indexing and then storing the data received from the Splunk Forwarder. In short, it changes data into events to store and add them to an index. This enhances the overall searchability.

First, the data received is parsed and all unwanted data is removed. The next step is indexing where files are created that are later bifurcated into different directories known as buckets. The files are -

  • Metadata files
  • Indexes pointing to raw data (.TSIDX files)
  • Compressed raw data

Applications of Splunk

Discussing all the applications of Splunk here is nearly impossible. Yes, you will be able to learn more about them during your Splunk course. And if you decide to go for Splunk certification, then you will get to know about everything during your training period. Here are a few applications of Splunk -
