Chapter 1: The Story of Splunk Splunk: The Company and the Concept The real excitement most people feel about Splunk comes from its ability to help solve the complex and recurring problems that Splunk customers have always had. The story of Splunk began in , when cofounders Erik Swan and Rob Das started looking around for their next challenge. Erik and Rob had done a couple of startups together and were looking for an idea for a new venture, so they started talking to companies about their problems. Erik and Rob asked prospective customers, How do you solve prob- lems in your infrastructure? Over and over again, Erik and Rob heard about practitioners experiences trying to troubleshoot IT problems and retrieve data by traditional means. The data was too spread out; it was hard to bring it all together and make sense of it. Everyone was attempting scripts to help them along.
The best part of Splunk is that it does not need any database to store its data as it extensively makes use of its indexes to store the data. Splunk is an absolutely fast engine and provides lightning fast results. You can troubleshoot any issue by resolving it with instant results and do an effective root cause analysis. Splunk can be used as a monitoring, reporting, analyzing, security information and event management tool among other things.
Splunk takes the valuable machine generated data and converts it into powerful operational intelligence by delivering insights through reports, charts and alerts. Why is Splunk so widely used? Splunk is by far the most widely used engine for working with machine-generated data. Today machine data is being generated at breakneck speeds. So Splunk is their natural choice to convert machine data into operational intelligence.
Splunk efficiently captures, indexes and correlates data from a searchable repository all in real-time and generates insightful graphs, reports, dashboards and alerts.
Since machine generated data will be the next frontier of big data, a huge of number of companies are investing heavily into making sense out of it and converting it into business advantage.
Splunk is also extensively used for security and compliance applications. Features of Splunk Here in this section of the Splunk tutorial we will discuss some of the top features of Splunk.
One of the biggest strengths of Splunk is real-time data processing The input data for Splunk could be in any format like CSV, JSON and others You can easily search and investigate a particular result with Splunk It lets you troubleshoot any condition of failure for improved performance You can monitor any business metrics and make an informed decision It is possible to visualize and analyze the results through powerful dashboards You can analyze the performance of any IT system with Splunk tool Splunk even lets you incorporate Artificial Intelligence into your data strategy.
Applications of Splunk We will discuss about some of the applications of Splunk to give you a brief idea about the vast possibilities of Splunk.
Why should you learn Splunk? In this section of the Splunk tutorial you will find out why you need to learn Splunk. As we discussed before, Splunk is the Google for machine data and going forward this machine data will be a major chunk of the big data that is being generated at breakneck speeds.
So if you learn Splunk then you have a very bright future thanks to increased deployed of Splunk in mission-critical applications cutting across industry verticals.
Today regardless of the industry vertical, Splunk is being implemented for indexing data, facilitating search and investigation, mapping knowledge to search, scheduling alerts and creating extensive reports and visualizations to aid business growth.
Recommended audience This Splunk tutorial is meant as the first step for anybody who wants to learn Splunk and excel in their careers. The data was too spread out; it was hard to bring it all together and make sense of it. Everyone was attempting scripts to help them along. The homegrown scripts were brittle, the peo- ple who wrote them sometimes left the company and took their expertise with them, and every new attempt to explore an issue would result in - tom assistance from the IT department.
These practitioners told Splunks founders that solving infrastructure problems was like slowly crawling around in caves their datacenters with pickaxes, poor lighting, and lim- ited navigational power old scripts and log management technologies.
In short, it was like spelunkingand so, the name Splunk was born. The founders were stunned that people were spending money on this widely acknowledged issue, and yet no one had stepped up to solve the problem.
Erik and Rob asked themselves, Why couldnt searching IT data be as easy and intuitive as a Google search? The mission of Splunk was to combine the ease of a web search with the power of the laborious, homegrown methods IT professionals were using to troubleshoot problems.
The product was a huge hit and immediately went vi- ral, spurred on by its availability as a free download.
Once downloaded, Splunk began solving broad range of unimagined customer problems and spread from department to department and from company to company. When users asked management to download it, they could already point to a record of solving problems and saving time with Splunk.
Originally conceived to help IT and datacenter managers troubleshoot technical problems, Splunk has grown to become an extremely useful platform for all kinds of business users because it enables them to search, collect, and organize data in a far more comprehensive, far less labor-in- tensive way than traditional databases.
The result is new business insights and operational intelligence that organizations have never had before. Splunk became popular with system admin- istrators, network engineers, and application developers as an engine to quickly understand and increase the usefulness of machine data. But why did they like it so much?
An example helps not only explain Splunks early popularity but also helps us understand the nature of machine data, which is central to the larger value that Splunk brings to the business world. In most computing environments, many different systems depend on each other. Monitoring systems send alerts after something goes wrong. For example, the key web pages of a site may depend on web servers, ap- application accelerators, caching systems, and so on.
When something goes wrong in one of these systems, say a database, alarms may start sounding at all levels, seemingly at once. When this happens, a system sometimes in different time zones, and contain millions of entries, most of which have nothing to do with the problem. In addition, the relevant recordsthe ones that indicate some failure of the systemtend to ap- all.
Lets look at how Splunk helps do this. Splunk begins with indexing, which means gathering all the data from diverse locations and combining it into centralized indexes.
Before Splunk, system administrators would have had to log in to 8 Chapter 1: The Story of Splunk many different machines to gain access to all the data using far less powerful tools. Using the indexes, Splunk can quickly search the logs from all servers and hone in on when the problem occurred.
With its speed, scale, and usability, Splunk makes determining when a problem oc- curred that much faster. Splunk can then drill down into the time period when the problem to head the issue off in the future.
Security analysts use Splunk to sniff out security vul- - ciencies and bottlenecks in complex applications.
