, Splunk - Overview
Splunk is a software which processes and brings out insight
from machine data and other forms of big data. This
machine data is generated by CPU running a webserver,
IOT devices, logs from mobile apps, etc. It is not necessary
to provide this data to the end users and does not have any
business meaning. However, they are extremely important to
understand, monitor and optimize the performance of the
machines.
Splunk can read this unstructured, semi-structured or rarely
structured data. After reading the data, it allows to search,
tag, create reports and dashboards on these data. With the
advent of big data, Splunk is now able to ingest big data
from various sources, which may or may not be machine
data and run analytics on big data.
So, from a simple tool for log analysis, Splunk has come a
long way to become a general analytical tool for
unstructured machine data and various forms of big data.
