Hi,
Splunk Enterprise is a powerful and versatile search and analysis engine that lets you investigate, troubleshoot, monitor, alert, and report on everything that's happening in your entire IT infrastructure from one location in real time. It indexes data from any application, server, or network device that makes up your IT infrastructure.
