Big data has incredible business value, and Splunk is the best tool for unlocking that value. Exploring Splunk shows you how to pinpoint answers and find patterns obscured by the flood of machinegenerated data. This book uses an engaging, visual presentation style that quickly familiarizes you with how to use Splunk. You'll move from mastering Splunk basics to creatively solving real-world problems, finding the gems hidden in big data.

Use this practical guide to the Splunk operational data intelligence platform to search, visualize, and analyze petabyte-scale, unstructured machine data. Get to the heart of the platform and use the Search Processing Language (SPL) tool to query the platform to find the answers you need. With more than 140 commands, SPL gives you the power to ask any question of machine data. However, many users (both newbies and experienced users) find the language difficult to grasp and complex. This book takes you through the basics of SPL using plenty of hands-on examples and emphasizes the most impactful SPL commands (such as eval, stats, and timechart). You will understand the most efficient ways to query Splunk (such as learning the drawbacks of subsearches and join, and why it makes sense to use tstats). You will be introduced to lesser-known commands that can be very useful, such as using the command rex to extract fields and erex to generate regular expressions automatically. In addition, you will learn how to create basic visualizations (such as charts and tables) and use prescriptive guidance on search optimization. For those ready to take it to the next level, the author introduces advanced commands such as predict, kmeans, and cluster. What You Will Learn Use real-world scenarios (such as analyzing a web access log) to search, group, correlate, and create reports using SPL commands Enhance your search results using lookups and create new lookup tables using SPL commands Extract fields from your search results Compare data from multiple time frames in one chart (such as comparing your current day application performance to the average of the past 30 days) Analyze the performance of your search using Job Inspector and identify execution costs of various components of your search Who This Book Is For Application developers, architects, DevOps engineers, application support engineers, network operations center analysts, security operations center (SOC) analysts, and cyber security professionals who use Splunk to search and analyze their machine data

This volume contains the proceedings of the 4th International Conference on - formation and Communications Security (ICICS2002). The three previous c- ferenceswereheldinBeijing(ICICS97),Sydney(ICICS99)andXian(ICICS01), where we had an enthusiastic and well-attended event. ICICS2002 is sponsored and organized by the Laboratories for Information Technology, Singapore, in co-operation with the Engineering Research Center for Information Security Technology of the Chinese Academy of Sciences and the International C- munications and Information Security Association (ICISA). During the past ?ve years the conference has placed equal emphasis on the theoretical and practical aspects of information and communications security and has established itself as a forum at which academic and industrial people meet and discuss emerging security challenges and solutions. We hope to uphold this tradition by o?ering you yet another successful meeting with a rich and interesting program. The response to the Call For Papers was overwhelming, 161 paper submissions were received. Therefore, the paper selection process was very competitive and di?cult–only41paperswereacceptedandmanygoodpapershadtoberejected. The success of the conference depends on the quality of the program. We are indebted to our program committee members and the external referees for the wonderful job they did.

"A celebration of the hidden beauty & variety of microscopic imagery."--Back cover.

The International Conference on Asian Digital Libraries (ICADL) is an annual international forum for participants to exchange research results, innovative ideas, and state-of-the-art developments in digital libraries. Built upon the successes of the first four ICADL conferences, the 5th ICADL Conference in Singapore was aimed at further strengthening the position of ICADL as a premier digital library conference that draws high quality papers and presentations from all around the world, while meeting the needs and interests of digital library communities in the Asia-Pacific region. The theme of the conference, “Digital Libraries: People, Knowledge & Technology,” reflects the shared belief of the organizers that success in the development and implementation of digital libraries lies in the achievement of three key areas: the richness and depth of content to meet the needs of the communities they intend to serve; the technologies that are employed to build user-centered environments through organization, interaction, and provision of access to that content; and the human elements of management policies, maintenance, and vision necessary to keep pace with new content, new technologies, and changing user needs.

This edition of our successful series to support the Cambridge IGCSE Physics syllabus (0625) is fully updated for the revised syllabus for first examination from 2016. Written by highly experienced author and teacher, Cambridge IGCSE Physics Coursebook with CD-ROM gives comprehensive and accessible coverage of the syllabus content. Suggestions for practical activities are included, designed to help develop the required experimental skills, with full guidance included on the CD-ROM. Study tips throughout the text, exam-style questions at the end of each chapter and a host of revision and practice material on the CD-ROM are designed to help students prepare for their examinations. Answers to the exam-style questions in the Coursebook are provided on the CD-ROM.

Saskatoon Public Library’s history is suffused with drama. Floods, fires, boardroom battles, clashes with City Hall, strikes,bold art robberies, outraged and belligerent patrons, pilfering and mutilation of materials, stalkers and flashers, animals at large on the premises, theft of computer equipment, and a covered-up dispute that sent its chief librarian fleeing into obscurity – all appear in these pages. Set these stormy incidents against a historical matrix of two world wars, a major Depression, world-wide epidemics, and a revolution in technology, and the colourful pageantry of the Saskatoon Library history emerges.But mostly the Library quietly hummed along – efficient, orderly and welcoming. It has been a symbol of public service, a haven for troubled souls, an escape for the bored, as well as a treasure house for information seekers. As an institution, the SPL has had a remarkably progressive history of service and compassion – even missionary zeal – reaching out to the disabled, the illiterate, the poor, “New Canadians” and Aboriginal folk.
