Splunk Wikipedia

A US company called Splunk is setting up a public collaborative website, or wiki, for IT professionals who hunt down system glitches. Splunk is today expected to launch a commercial version of a hosted service called Splunk Base, which aims to be the equivalent of an online encyclopaedia, like Wikipedia, but for technology administrators.
Splunk Base is a hosted wiki where system administrators can post information on errors they encounter while running data centres. A database administrator, for example, might report a problem that often occurs when setting up an Oracle database to run with Apache Web server.
The system, which is available for free, allows administrators to tag, or label, their entries so other users can more quickly find solutions to their system woes. The company name is a play on "spelunking," or cave exploration.
