The overwhelming majority of a software system’s lifespan is spent in use, not in design or implementation. So, why does conventional wisdom insist that software engineers focus primarily on the design and development of large-scale computing systems? In this collection of essays and articles, key members of Google’s Site Reliability Team explain how and why their commitment to the entire lifecycle has enabled the company to successfully build, deploy, monitor, and maintain some of the largest software systems in the world. You’ll learn the principles and practices that enable Google engineers to make systems more scalable, reliable, and efficient—lessons directly applicable to your organization. This book is divided into four sections: Introduction—Learn what site reliability engineering is and why it differs from conventional IT industry practices Principles—Examine the patterns, behaviors, and areas of concern that influence the work of a site reliability engineer (SRE) Practices—Understand the theory and practice of an SRE’s day-to-day work: building and operating large distributed computing systems Management—Explore Google's best practices for training, communication, and meetings that your organization can use

The book describes data-driven approach to optimal monitoring and alerting in distributed computer systems. It interprets monitoring as a continuous process aimed at extraction of meaning from system's data. The resulting wisdom drives effective maintenance and fast recovery - the bread and butter of web operations. The content of the book gives a scalable perspective on the following topics: anatomy of monitoring and alerting conclusive interpretation of time series data-driven approach to setting up monitors addressing system failures by their impact applications of monitoring in automation reporting on quality with quantitative means and more!

Among the issues confronting America is long-term care for frail, older persons and others with chronic conditions and functional limitations that limit their ability to care for themselves. Improving the Quality of Long-Term Care takes a comprehensive look at the quality of care and quality of life in long-term care, including nursing homes, home health agencies, residential care facilities, family members and a variety of others. This book describes the current state of long-term care, identifying problem areas and offering recommendations for federal and state policymakers. Who uses long-term care? How have the characteristics of this population changed over time? What paths do people follow in long term care? The committee provides the latest information on these and other key questions. This book explores strengths and limitations of available data and research literature especially for settings other than nursing homes, on methods to measure, oversee, and improve the quality of long-term care. The committee makes recommendations on setting and enforcing standards of care, strengthening the caregiving workforce, reimbursement issues, and expanding the knowledge base to guide organizational and individual caregivers in improving the quality of care.

Are commands such as free, vmstat, slabtop, iostat, dstat, ifstat, mpstat useful? The micro-course discusses the most popular commands enabling an analysis of the system status starting from checking the load of the processor, the amount of the operating memory used and finishing with the analasys of using input-output devices. Commands for collecting statistics on the above topic, both in real time and in given time intervals, were discussed.

Work on the monitor has concentrated on three aspects: furthering the conceptual design, implementing the lower level mechanisms of the monitor and designing and implementing the relational monitor. At this point, we have a fairly complete idea of the tasks the various components perform and how these components will interact. The components are: StarMon, low level data collection under the StarOS operating system on CM*, consisting of two processes: Accountant, interfaces to the Simon Accountant via the EtherNet; MonProc, performs name translation, enabling of events and miscellaneous services. Medic, low level collection under the Medusa operating system on CM*, Simon Accountant interfaces with the resident monitor (either StarMon or Medic using a system-independent protocal; Simon, the computing engine' for deriving high level information from event records; Control, accepts queries from the user in a declarative language and translates these queries into update networks for Simon. At this point, the first three components are nearing completion. Once their condition is stable, sensors will be placed throughout both StarOS and Medusa to provide a source of event records for Simon. The structure of Simon has been implemented, although more work is necessary. The Control component has been partially designed and is in the early stages of implementation. Also the a Sensor Definition facility has been designed and implemented.

Europe is facing a paradox: while governments try to curb public spending, the demands on our healthcare systems continue to rise. The use of smart technologies and innovation can help to address the challenges faced by healthcare systems today, such as an ageing population, a shortage of healthcare professionals and restrictions on financial resources. But despite increasing evidence of the benefits technology can bring, the healthcare sector has been slow to embrace the digital revolution, and has stuck to more traditional methods and models. This book presents selected contributions to the symposium on Personal Health Monitoring (PHM) and Ethics and future areas of PHM, which took place in advance of the 11th World Congress of Bioethics, held in Rotterdam, the Netherlands, in June 2012. Most of the papers present the outcomes of the European PHM-Ethics project, which conducted interdisciplinary analyses of emerging PHM applications. Additional invited contributions deal with important issues related to the project’s primary objectives and outcomes. The project is strongly associated with the new e-Health Action Plan, launched by the European Commission in December 2012, which is designed to bring the benefits of digital solutions into healthcare systems. The book covers a broad spectrum, ranging from the technical setup of PHM systems to ethical issues raised by PHM applications, and will be of interest to all those concerned with improving the provision of healthcare worldwide.
