Splunk is an American multinational corporation based in San Francisco, California, which produces software for searching, monitoring, and analyzing machine-generated big data, via a web-style interface.[1]

Splunk (the product) captures, indexes and correlates real-time data in a searchable repository from which it can generate graphs, reports, alerts, dashboards and visualizations.[2][3]

Splunk aims to make machine data accessible across an organization and identifies data patterns,[4] provides metrics, diagnoses problems and provides intelligence for business operation. Splunk is a horizontal technology used for application management, security and compliance, as well as business and web analytics.[1] Splunk has over 7,900 customers worldwide.[5]

The company was started in 2003 by co-founders Michael Baum, Rob Das and Erik Swan.[6] The name "Splunk" is a reference to exploring caves, as in spelunking. Splunk is based in San Francisco, with regional operations across EMEA and Asia and has over 900 employees.[7] Splunk is venture funded, having raised 40 million USD by 2007[8] and became profitable in 2009.[9] In 2012, Splunk had its initial public offering, trading under NASDAQ symbol SPLK. In September 2013, the company bought Bugsense, a mobile device data analytics company.[10]


Splunk can perform real-time and historical search, as well as reporting and statistical analysis. The product can index structured or unstructured textual machine-generated data. Search and analytics operations are specified using Search Processing Language, created for managing machine-generated big data. Originally based upon Unix Piping and SQL, its scope includes data searching, filtering, modification, manipulation, insertion, and deletion.

In 2011, Splunk released Splunk Storm, a cloud-based version of the core Splunk product. Splunk Storm offers a turnkey, managed and hosted service for machine data.[11]

In 2013, Splunk announced a product called Hunk: Splunk Analytics for Hadoop, which supports accessing, searching, and reporting on external data sets located in Hadoop from a Splunk interface.[12]

In 2013, Splunk announced that Splunk Storm would become a completely free service and expanded its cloud offering with Splunk Cloud.[13]


Splunk offers its main software in two license types: —an Enterprise License designed for companies and large organizations, and a gratis License[14][15] designed for personal use. The freeware version is limited to 500 MB of data a day, and lacks some features of the Enterprise license edition.

As of the release of Splunk Cloud, Splunk Storm is free and includes 20GB of data storage.[16]


Splunk was designed for use in information technology operations; it is also used in other ways.[17] Users in IT operations include Metropcs,[18] Ceryx,[19] and Denver Water.[20] Cars.com,[21][22] Domino's Pizza,[23] and National Public Radio[24] are among those who use it for web analytics. In the Internet of Things it is used by the Bangkok Metropolitan Administration Department of Drainage and Sewage to send alerts,[25] by Eglin Air Force Base for energy conservation,[26] by Nest Labs to analyze thermostat data,[citation needed] by iRhythm to check on product performance[citation needed] and by an elevator company to monitor elevator usage.[27] In computer security it is used by the University of Connecticut,[28] and by federal and state agencies.[29] It is used to help with regulatory compliance by Barclays bank,[30][31] Credit Suisse,[citation needed] Monster.com, [32] and Sportsbet.com.au.[33]
