Splunk is a well-known software platform that is vastly used for analyzing, searching, monitoring, and visualizing the data generated by the machine in real-time. It helps produce dashboards, graphs, and visualizations by capturing the real-time data, indexing them, and correlating them in a searchable container.

Splunk is beneficial in providing solutions to various business problems. It allows easy access to data over the whole organization that helps in easy diagnostics for the issues and helps in drawing the solutions.

Splunk allows you to track and read the computer data. These data can be seen as indexer events and log files. It also allows you to view these data in various dashboard formats. Splunk analyzes these logs and semi-structured data by different processes with defined data modeling as per the requirements of the IT industries.

Splunk can specify the data produced by users through the web, apps, sensors, or computers. It has a built-in function for defining the data types, field separators, and search process optimization. You can also produce visualization for these search result data.

Features of Splunk include:

• It helps you build real-time data applications.
• It generates ROI faster.
• It allows you to accelerate the development and testing of the applications.
• With the help of real-time architecture, you can have Agile statistics and reports.
• It empowers its users of all kinds by offering search, analysis, and visualization techniques.

Splunk is available in three different versions:

• Splunk Enterprise

A vast number of IT businesses use the Splunk Enterprise version. It allows you to collect and analyze the data from websites, applications, etc.

• Splunk Cloud

It has similar features as the Splunk Enterprise. It is a hosted platform that can also be availed using the AWS cloud platform or with Splunk.

• Splunk Light

It is a free version that helps you search, report, and alter your log data. Compared to other versions, this version has limited features and functionalities.

Below are the essential components of Splunk architecture:

• Universal Forwarder (UF)

Universal Forwarder is a lightweight component that forwards the data to the heavy Splunk Forwarder. You can mostly see UF at the client-side or the application server. The main feature of UF is to deliver the log data. 

• Load Balancer (LB)

It is a default load balancer. You can also use your personalized load balancer.

• Heavy Forwarder (HF)

HF is a heavy Splunk component that helps you in filtering the data.

• Indexer

The indexer in Splunk allows you to index the stored data through which the Splunk search performance is improved. Indexing is the default feature of Splunk.

• Search Head (SH)

SH is used for obtaining intelligence and carrying out reporting.

• Deployment Server (DS)

DS allows you to deploy the configurations and share them among the components.

• License Manager (LM)

License is based on usage and volume. Splunk regularly checks the licensing details.

Forwarder in Splunk collects the data across the remote machines and forwards them to the indexer. The indexer then processes the data and indexes them on a disk. All these happen in a real-time scenario. Then comes the end user who interacts with Splunk through search head where the user can search, analyze, and visualize these data. This is how Splunk works.

Many famous companies work with Splunk. Some of them are:
