Splunk: Overview of functionality

Splunk is great at analyzing large sets of unstructured data quickly and easily. To simulate working with a stream of data, I am using a log file I pulled from a server. You can download it here: event

Load this into Splunk through data upload button. You can just hit next through the remaining upload screens. The default setting work just fine for us.

But for something cool, click on the Patterns tab. This shows interesting patterns Splunk has sniffed out on its own.

When you save the report, Splunk gives you a default option to add a Time Range Picker that will let you pick a time range next time you run the report.

I personally recommend playing with Splunk to get a better feel for it. What is so cool about it is how quickly and easily you can produce actionable analytics.
