Introduction to Splunk

Splunk is a software which processes and brings out insight from machine data and other sorts of big data. This machine data is generated by CPU running a webserver, IOT devices, logs from mobile apps, etc. it’s not necessary to supply this data to the top users and doesn’t have any business meaning. However, they’re extremely important to know, monitor and optimize the performance of the machines.
Splunk can read this unstructured, semi-structured or rarely structured data. After reading the info, it allows to look , tag, create reports and dashboards on these data. With the arrival of massive data, Splunk is now ready to ingest big data from various sources, which can or might not be machine data and run analytics on big data.
So, from an easy tool for log analysis, Splunk has come an extended thanks to become a general analytical tool for unstructured machine data and various sorts of big data.

Product Categories

Splunk is out there in three different product categories as follows −

Splunk Enterprise − it’s employed by companies which have large IT infrastructure and IT driven business. It helps in gathering and analyzing the info from websites, applications, devices and sensors, etc.
