With the newest update of its machine-data search engine, Splunk has expanded the user interface in a number of ways so it can be more easily used by business analysts as well as system administrators.

The Splunk software collects and indexes machine data, such as server logs, so they can be analyzed for troubleshooting and usage trends. Although Splunk was originally used mostly for system troubleshooting, more organizations have been using it for discovering usage trends of their systems, which can be used to better customize products and services. National Public Radio, for instance, has used the software for advanced Web analytics.
While Hadoop has been getting quite a bit of publicity lately for being a technology for big data-styled analysis, Splunk can also be used to sift through large amounts of data, noted Curt Monash of Monash Research. "Whatever data you can extract from your logs, there is a good chance that Splunk can help," he said.
To help introduce Splunk to a wider array of users, Splunk has revamped the user interface. With the new version, users can rearrange the dashboards directly from dashboards themselves. The previous version required making changes to a text-based XML file. "Everything is editable through dashboards on your desktop or on your tablet," Mehta said. Users can change around the order of the data charts on the dashboard, or change chart types, for instance, swap out a pie chart for a histogram.
Through the Splunk query language, users can also juxtapose different variables, such as time of day and types of users, to create entirely new charts. Once a user specifies a search through Splunk's query language, that query can be scheduled to run on regular intervals and the results posted in visual form, through charts and other visualizations.
The software now supports a new type of visualization, called sparklines. Created by visualization guru Edward Tufte, Sparklines merge many individual data points into a single illustration that stretches across the screen. "You can not only look at the macro timeline for a search, you can see the granular trending as well," Mehta said. The new version also allows users to fold in historical data with real-time data, expanding the scope of searches.
