Splunk 4.3 gets a boost for business analysis

Splunk has updated its flagship machine-data search engine for more big data-styled analysis

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.

Splunk Enterprise 4.3, the first update in over a year, replaces the old interface, which was based on Adobe Flash, with one built on HTML5 and JavaScript. This allows Splunk to be accessed from a wider range of devices, perhaps most notably the Apple iPad, said Sanjay Mehta, senior director of product marketing at Splunk. "Having this capability means customers can access important information on the go," he said.

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.

The software also features a number of improvements on the administrative end. The company claims the new version can work up to 10 times faster, due to a number of reasons. The software has been refactored to allow for many more concurrent users within a single deployment of software, noted Steve Sommer, Splunk chief marketing officer. The software also implements a Bloom Filter, a mathematical technique for filtering out large swaths of irrelevant data for certain types of searches.

A Bloom Filter can "exclude looking at the individual event details and just look at the one data structure, which will allow us to drastically improve search performance," Sommer said.

The software can also support multiple LDAP (Lightweight Directory Access Protocol) implementations, making it accessible across large enterprises with multiple user directories.

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
