Apache Splunk software is used to search and analyze machine data. The machine data will be from web applications, sensors, devices or any other data generated in many processes. It can also  make semi-structured data with proper modelling. This has many features to recognise the data types, field separators and also optimise the search processes. This provides data visualisation on the search results.

Splunk is a program that highlights the search and also analysis of computer data. This analyses semi-structured data and logs creating many processes with proper data modelling as the need of the IT companies. The user generates the data by means of any device like web apps, sensors or computers. It is having built-in functions, data types and field separators and also search engine optimisation. The students of the IT developers  and experts IT management who want to develop a strong understanding of basic Splunk concepts that should read. There are many benefits such as

1. Real time screen visibility.

2. Splunk will provide better interface.

3. It also provides instant results, it reduces troubleshooting and time solving.

4. This is one of the most effective methods of study of root causes.

5. This splunk will permit the generation of graphs, warnings and dashboards.

6. Similar findings will be quickly checked and analyzed using splunk.

7. This will enable the troubleshoot any failure state to improve the performance.

8. This helps us to gather many Operational Intelligence from the system data.

9. This splunk may allow us to recognise any data type like .csv, json, log formats.

The splunk is having many features like

1. This will accelerate the development and testing.

2. There are building of real-time data applications.

3. Generate ROI faster.

4. There are agile figures and real time architecture documentation.

5. Splunk will provide search analysis and visualizations capabilities to empower  users.

There are many splunk versions. They are

• Splunk enterprise
• Splunk Light
• Splunk Cloud

Splunk enterprises:

There are many big IT enterprise versions. As required of the splunk tool, this collects and analyze the data for mobile phones, websites and applications.

Splunk Cloud:

Splunk cloud is website that is the host. This accepts same features as the company version. This will be used from splunk or may be cloud platform AWS.

Splunk Light:

There is free version of splunk illumination. It enables, scanning, recording and editing of your log data.

The main features of Splunk are:

1. Data Ingestion

In this Splunk, we can import or insert the date from the different formats like JSON, XML and also weblogs and also application logs the unstructured system data. This unstructured data will be modelled as the consumer wants in data structure.

2. Data Index

Splunk indexes the ingested data easier search and query on different conditions.

3. Data searching

Splunk will analysis includes indexed data and also establish graphs,to forecast future trends.

4. Using Alerts

This is used to trigger emails or RSS feeds when a certain requirement is identified in the data which is being analyzed.

5. Dashboards

When searching anything the search anything the search result will be displayed in the dashboard in the maps, reports etc.

6. Data Model

The indexed data may be modelled into one and many other data sets or may be domain experts. This will configure straightforward  navigation by the end users.

What is Splunk used for?

Consider the sysadmin is trying to figure out what went wrong in system’s hardware and we stumble upon the logs like the one’s in the above image what would be possibly do? This would be able to locate in which step your hardware that failed you? This nutshell  of machine data will be

• Complex to understand
• In the unstructured format
• It is not suitable for making analysis.It is where the tool splunk comes handy.
