If you're responsible for maintaining the integrity and availability of a mission-critical UNIX system, then you need UNIX Fault Management: A Guide for System Administrators, the first book that brings together all of the monitoring and fault management information. Expert UNIX system management engineers Brad Stone and Julie Symons show you exactly how to implement appropriate, cost-effective system monitoring on any UNIX server -- including systems configured as high availability clusters. You'll learn how to:
-
Plan for-and establish-cost-effective, reliable system monitoring procedures
-
Monitor systems, disks, networks, applications, and databases
-
Detect, investigate, and recover from server problems
-
Implement best practices for high availability in enterprise-class UNIX installations-including clusters
-
Take advantage of key fault management trends, new standards, and new technologies
This book contains detailed descriptions of fault monitoring tools and monitoring frameworks to help you make better purchasing decisions. You'll also find a handy quick reference of monitoring tasks and techniques for operators -- including specific, step-by-step recovery solutions. If you can't afford one nanosecond more downtime than necessary, you can't afford to be without UNIX Fault Management.
This book is intended for system administrators and operators who are responsible for maintaining the integrity and availability of mission-critical UNIX systems. The book provides a description of the fault monitoring tools and techniques available for UNIX servers, including systems that are configured as high availability clusters. This book can therefore be a handy quick reference for an operator trying to troubleshoot a problem in the customer environment, by pointing out where to find key diagnostic messages and describing how to take recovery actions.
A system administrator responsible for the initial configuration and administration of UNIX systems will also find this book useful because it describes the procedures to follow to set up the appropriate levels of system monitoring. The product descriptions can also help in making purchasing decisions as the customer determines the appropriate amount of event monitoring needed in their environment.
An overview of the tasks performed by an operator is provided, with details on how events are received and processed. The remainder of the book focuses on the types of events that can be received, how they are detected, how operators receive event notifications, and how problems can be investigated and recovery performed. The goal is to introduce the necessary tools, but not to show how every possible problem can be solved.
This book provides numerous descriptions of how fault management tools and products can be used to solve a variety of problems. Many of the chapters are focused on specific computer components, such as disks or databases, to be helpful to operators with specific roles.
