Editor's Notes
- #2 Background: This is a workshop designed to introduce new and experienced users to Splunk reports and dashboards. It was a little surprising, but not uncommon, to learn from some of our favorite Splunkers they didn’t know Splunk could create interactive, smart visuals like graphs/charts/reports and arrange them quickly on custom dashboards. This 30-45 minute workshop will catapult searchers into a whole new world of visualizations.
- #5 Splunk’s mission is to make YOUR machine data accessible, usable and valuable to everyone. It’s this overarching mission that drives our company and products that we deliver.
- #6 Data is growing and embodies new characteristics not found in traditional structured data: Volume, Velocity, Variety, Variability. Machine data is one of the fastest, growing, most complex and most valuable segments of big data. All the webservers, applications, network devices – all of the technology infrastructure running an enterprise or organization – generates massive streams of data, in an array of unpredictable formats that are difficult to process and analyze by traditional methods or in a timely manner. Why is this “machine data” valuable? Because it contains a trace - a categorical record - of user behavior, cyber-security risks, application behavior, service levels, fraudulent activity and customer experience.
- #7 All of this is accomplished with: No backend database No custom connectors Without filtering data Without knowing the questions before hand. While Providing a quick time to value With agile statistics and reporting All in real-time
- #8 Getting data into Splunk is designed to be as flexible and easy as possible. In most cases you’ll find that no configuration is required; you just have to determine what data to collect and which method you want to use to get it into Splunk. Splunk is THE universal machine data platform. It goes beyond ingesting just log files, ingesting data from syslog, scripts, system events, API’s, even wire data! The result is beautifully indexed time-based series events, previously in disparate silos that can now be cross-correlated and made accessible to everyone your organization. Notice here that we are ingesting local files, data from syslogs, output from scripts and even wire data. Let’s see how the Splunk platform supports all this data collection.
- #9 Some machine data contains human-generated content. For example this logfile from a safety app on a technicians mobile device. The application allows them to easily report either positive, negative or neutral safety observations on a regular basis. (logfile – timestamp, app_id, etc.)
- #10 Some machine data contains human-generated content. For example this logfile from a safety app on a technicians mobile device. The application allows them to easily report either positive, negative or neutral safety observations on a regular basis. (logfile – timestamp, app_id, etc.)
- #16 It only takes minutes to download and install Splunk on the platform of your choice, bringing you fast time to value. Once Splunk has been downloaded and installed the next step is to get data into a Splunk instance. The data then becomes searchable from a single place! Since Splunk stores only a copy of the raw data, searches won’t affect the end devices data comes from. Having a central place to search your data not only simplifies things, it also decreases risk since a user doesn’t have to log into the end devices. Splunk can be installed on a single small instance, such as a laptop, or installed on multiple servers to scale as needed. The ability to scale from a single desktop to an enterprise is another of our key differentiators. When installed on multiple servers the functions can be split up to meet any performance, security, or availability requirements.
- #17 Lets say you are a Web Site Administrator. You recently received user complaints that that web pages are failing and not returning content when it should. Let’s use Splunk to search this data, to not only determine problems that happened but factors associated with or contributing to it.
- #18 Start up a brand new Splunk Have a ready data set, typically use tutorial Literally drag and drop. Go back to components, what make them up Run two manual queries, paints picture of we can do. Patterns Create a data model (Use instant pivot) Create output Do something completely impressive. (create party on third party system, 3d graph, alert, something tangible outside of Splunk) Highlight best Splunk 6 features, add data, patterns, instant pivot,
- #25 “After this workshop, if you want more information, all the product documentation is available online. The documentation is divided into several manuals. For reporting and dashboards you will likely be most interested in the User and Developer Manuals.”
- #26 “For a more interactive approach to getting your questions addressed there is Splunk Answers. It is a web based Splunk community of Splunkers like you. Splunk employees are also regular experts on the site.”
- #28 “It is not possible to cover everything you need to know about building reports and dashboards in 30-45 minutes. For more structured training with labs, consider Splunk education courses. These are available as instructor-led web-based courses or onsite if there is enough participants per class.”
