![]() The other thing that Splunk has copied from Google is speed. Splunk creates a drop-down with the most frequently found terms in your logs that contain what you've typed so far, along with the frequency counts. Start typing in the search bar and pause for a moment. Immediately, log entries that have the text you typed begin showing up, while the query continues to run in the background if you selected a particularly wide time range.īut this isn't just your normal text search. Splunk has intentionally copied the Google minimalist search bar, and to find information you just start typing into a large box, selecting a time range, and clicking the green "go" button. If getting information into Splunk takes a while, getting information out of Splunk is a breeze, and can be fun to boot. Plan on spending more than a few moments getting started. Overall, getting data into Splunk is hard, with a confusing maze of pointers, wikis, product tech notes and documentation, but backed up by Splunk’s technical support staff. But in these days of compliance and audits, having centralized Syslog for archiving purposes doesn’t seem that unusual.". Have a central Syslog server that re-sent the log data over to Splunk for indexing. Our installation is slightly complicated, because we already We got Splunk working very smoothly in our multi-vendor environment, but only after investing serious effort in understanding how Splunk collects and indexes data. If you want to make Splunk work, you've got to be ready to abandon the slick GUI and dive deep into difficult technical configuration, editing configuration files, writing regular expressions, and taking the time to understand where your data are coming from and how Splunk will see them. Splunk has an internal complexity that the Splunk team is happy to share with everyone through an extensive on-line documentation system. Splunk is not a do-it-yourself piece of open source software, but it also doesn't have the smooth polish we have seen from other commercial products. Our initial contact with Splunk's input system, however, gave us a pretty good feel for Splunk's operational style. Splunk isn't too particular about where and how it gets data, with options for scripting and other network input sources. We only used it to pull Windows event log information. The Universal Forwarder can also monitor file systems for changes and forward data from remote systems back to a central Splunk installation. We set up Splunk on a Linux system ( Windows and other Unix flavors are also supported), a simple matter of an RPM installation, and had it listen for data sent to it with Syslog, probably the most common way to get your log data off systems and into an analysis tool.įor Windows systems, Splunk provides their "universal forwarder," an application that will pull Windows WMI data and forward it off to a Splunk server. Getting data into Splunk follows the same paths as any log management solution. ![]() ![]() We didn't want to go quite that large, so we tested using Splunk on our own small data center, using live data. Splunk wants to be fed everything, including system, web, security, and every other type of log or performance data you can find. With distributed search databases, role-based access control, and the ability to eat terabytes of log data each day, Splunk is aimed at the large enterprise. ![]() Some features, such as alerting, role-based access control, and distributed searching are not available in the free version you also can't run premium applications on top of the free version.īut Splunk is designed to scale up, way, way, up. There's a free version of Splunk for small and midsized deployments, so if your log files don't add up to 500MB each day, Splunk can be yours for the cost of the server you run it on. Network managers who look at their logs every day, and those who wish they could get useful performance, capacity, and security information out of the gigabytes of log data stacking up should take a close look at Splunk. But Splunk pays off in the power that it brings, and the information it can pull out of your logs. Moving from a simple syslog server or event viewer with a "search" command to Splunk is not a one-day operation. We found Splunk to be a powerful, if complicated, tool. What separates out Splunk from the world of Syslog servers and SIEM tools is Splunk Apps, a library of nearly 200 add-ons that make Splunk smarter about particular types of log information, change its look-and-feel, or add new types of analysis. ![]()
