Available in PDF, EPUB and Kindle. Book excerpt: Since most applications today are distributed in some fashion, monitoring their health and performance requires a new approach. Enter distributed tracing, a method of profiling and monitoring distributed applications—particularly those that use microservice architectures. There’s just one problem: distributed tracing can be hard. But it doesn’t have to be. With this guide, you’ll learn what distributed tracing is and how to use it to understand the performance and operation of your software. Key players at LightStep and other organizations walk you through instrumenting your code for tracing, collecting the data that your instrumentation produces, and turning it into useful operational insights. If you want to implement distributed tracing, this book tells you what you need to know. You’ll learn: The pieces of a distributed tracing deployment: instrumentation, data collection, and analysis Best practices for instrumentation: methods for generating trace data from your services How to deal with (or avoid) overhead using sampling and other techniques How to use distributed tracing to improve baseline performance and to mitigate regressions quickly Where distributed tracing is headed in the future
Download or read book Distributed Debugging An Integrated Approach written by Stephen Lesavich and published by Coconut Avenue, Inc.. This book was released on 1991-03-15 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and development of digital computer software for distributed concurrent programming environments has increased significantly in the past few years. The presence of remote processors and concurrency greatly complicates the creation, analysis, testing, and debugging of all software produced for these environments. It appears that few tools developed for sequential environments are adequate for debugging software programs in a distributed concurrent environment. The distributed concurrent environment also presents the need for special debugging tools that were not needed for sequential environments. This research will present a new model for debugging programs in a distributed concurrent programming environment. This new model was used to design, develop, and implement an integrated, cooperating set of concurrent debugging tools. The new debugging model and tool set were used in a distributed Concurrent C development environment running under the UNIX® operating system and connected by an Ethernet local area network. Actual results obtained from using the new debugging scheme and integrated debugging tool set to detect, locate, and correct software faults in distributed Concurrent C programs are also presented.
Download or read book Knowledge based Software Development for Real time Distributed Systems written by Jeffrey J.-P. Tsai and published by World Scientific. This book was released on 1993 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interplay of artificial intelligence and software engineering has been an interesting and an active area in research institution and industry. This book covers the state of the art in the use of knowledge-based approaches for software specification, design, implementation, testing and debugging. Starting with an introduction to various software engineering paradigms and knowledge-based software systems, the book continues with the discussion of using hybrid knowledge representation as a basis to specify software requirements, to facilitate specification analysis and transformation of real-time distributed software systems. A formal requirements specification language using non-monotonic logic, temporal logic, frames and production systems for new software engineering paradigms (such as rapid prototyping, operational specification and transformational implementation) is also discussed in detail. Examples from switching and other applications are used to illustrate the requirements language. Finally, the development, specification and verification of knowledge-based systems are investigated.
Download or read book Understanding Distributed Systems Second Edition written by Roberto Vitillo and published by Roberto Vitillo. This book was released on 2022-02-23 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Learning to build distributed systems is hard, especially if they are large scale. It's not that there is a lack of information out there. You can find academic papers, engineering blogs, and even books on the subject. The problem is that the available information is spread out all over the place, and if you were to put it on a spectrum from theory to practice, you would find a lot of material at the two ends but not much in the middle. That is why I decided to write a book that brings together the core theoretical and practical concepts of distributed systems so that you don't have to spend hours connecting the dots. This book will guide you through the fundamentals of large-scale distributed systems, with just enough details and external references to dive deeper. This is the guide I wished existed when I first started out, based on my experience building large distributed systems that scale to millions of requests per second and billions of devices. If you are a developer working on the backend of web or mobile applications (or would like to be!), this book is for you. When building distributed applications, you need to be familiar with the network stack, data consistency models, scalability and reliability patterns, observability best practices, and much more. Although you can build applications without knowing much of that, you will end up spending hours debugging and re-architecting them, learning hard lessons that you could have acquired in a much faster and less painful way. However, if you have several years of experience designing and building highly available and fault-tolerant applications that scale to millions of users, this book might not be for you. As an expert, you are likely looking for depth rather than breadth, and this book focuses more on the latter since it would be impossible to cover the field otherwise. The second edition is a complete rewrite of the previous edition. Every page of the first edition has been reviewed and where appropriate reworked, with new topics covered for the first time.
Download or read book Debugging Systems on Chip written by Bart Vermeulen and published by Springer. This book was released on 2014-07-14 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes an approach and supporting infrastructure to facilitate debugging the silicon implementation of a System-on-Chip (SOC), allowing its associated product to be introduced into the market more quickly. Readers learn step-by-step the key requirements for debugging a modern, silicon SOC implementation, nine factors that complicate this debugging task, and a new debug approach that addresses these requirements and complicating factors. The authors’ novel communication-centric, scan-based, abstraction-based, run/stop-based (CSAR) debug approach is discussed in detail, showing how it helps to meet debug requirements and address the nine, previously identified factors that complicate debugging silicon implementations of SOCs. The authors also derive the debug infrastructure requirements to support debugging of a silicon implementation of an SOC with their CSAR debug approach. This debug infrastructure consists of a generic on-chip debug architecture, a configurable automated design-for-debug flow to be used during the design of an SOC, and customizable off-chip debugger software. Coverage includes an evaluation of the efficiency and effectiveness of the CSAR approach and its supporting infrastructure, using six industrial SOCs and an illustrative, example SOC model. The authors also quantify the hardware cost and design effort to support their approach.

Download or read book Tools and Environments for Parallel and Distributed Systems written by Amr Zaky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing correct and efficient software is far more complex for parallel and distributed systems than it is for sequential processors. Some of the reasons for this added complexity are: the lack of a universally acceptable parallel and distributed programming paradigm, the criticality of achieving high performance, and the difficulty of writing correct parallel and distributed programs. These factors collectively influence the current status of parallel and distributed software development tools efforts. Tools and Environments for Parallel and Distributed Systems addresses the above issues by describing working tools and environments, and gives a solid overview of some of the fundamental research being done worldwide. Topics covered in this collection are: mainstream program development tools, performance prediction tools and studies; debugging tools and research; and nontraditional tools. Audience: Suitable as a secondary text for graduate level courses in software engineering and parallel and distributed systems, and as a reference for researchers and practitioners in industry.

Download or read book UML Assisted Visual Debugging for Distributed Systems written by Benjamin R. Musial and published by . This book was released on 2003-03 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The DOD is developing a Joint Battlespace Infosphere, linking a large number of data sources and user applications. To assist in this process, debugging and analysis tools are required. Software debugging is an extremely difficult cognitive process requiring comprehension of the overall application behavior, along with detailed understanding of specific application components. This is further complicated with distributed systems by the addition of other programs, their large size and synchronization issues. Typical debuggers provide inadequate support for this process, focusing primarily on the details accessible through source code. To overcome this deficiency, this research links the dynamic program execution state to a Unified Modeling Language (UML) class diagram that is reverse-engineered from data accessed within the Java Platform Debug Architecture. This research uses focus + context, graph layout, and color encoding techniques to enhance the standard UML diagram. These techniques organize and present objects and events in a manner that facilitates analysis of system behavior. High-level abstractions commonly used in system design support debugging while maintaining access to low-level details with an interactive display. The user is also able to monitor the control flow through highlighting of the relevant object and method in the display.
Download or read book Query based Debugging of Distributed Systems written by Ryan Evans Braud and published by . This book was released on 2010 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenging aspects of debugging distributed systems is understanding system behavior in the period leading up to a bug. Since traditional debuggers such as gdb are not well suited to distributed system debugging, developers often resort to annotating their code with log statements and then writing one-off scripts that perform ad-hoc searches through the logged data. To improve this cumbersome process, we propose that the state of a distributed system execution should be programmatically and interactively available for postmortem analysis. We observe that the three defining properties of entries in a distributed system's log are "time," "node identifier," and "event type," and treat the log as a logical cube with these dimensions. By exploiting the structure of this state matrix, developers can use a high-level query language to efficiently extract information instead of manually inspecting log files or writing log processing scripts. In this dissertation, we describe the debugging process based on a query-oriented approach. We begin with an introduction of the state matrix abstraction and show how it can capture useful properties of distributed systems' executions. We then present NyQL, an object-oriented query language operating over the contents of the state matrix and describe one possible implementation as a translation to SQL queries executed over a relational database. Next, we present an implementation of a logging system that generates queryable logs in Mace, a source-to-source translator and library for building distributed systems. We present techniques for mitigating the logging overhead by giving NyQL queries to the \mace translator and show that in many cases queries can be resolved in a few seconds. We then demonstrate how using NyQL simplified debugging a handful of bugs in two different distributed systems. Finally, we extend our logging techniques to systems without source-to-source translators by developing two general-purpose libraries & mdash one in C++ and one in Java. We describe the differences between all three systems in terms of functionality and ease of use and then conclude with some future directions for distributed systems debugging.
