The performance performance management of a computer systemcomputer system is a measurement of how well the system is able to respond to the workload that is being put onto it. The performance management of a system is the set of tasks that ensures that the system performance is satisfactory for its intended purpose.
The operational life cycle is the longest life stage in the life cycle of a computer systemcomputer system and also the most important from the perspective of systems management. The job of systems management is to keep the system running smoothly without problems during this life stage.
A fault in the computer systemcomputer system is the failure of a component which prevents the computer systems from operating normally. As the computer system operates, it may experience faults due to a variety of reasons. Each fault would generate some type of alerts or error messages to be reported in the monitoring infrastructure. These monitored alert messages will be stored in the management...
There are several subjects that are related to systems management which a student of the subject ought to be aware of, because they are closely related, or advanced subjects in systems management. In this chapter, we provide a brief review of those subjects.
The goal of systems management is to try to keep computer systems and network running properly and flawlessly. In order to do so, computer systems must be accessible to the people who are authorized to use them, and not be accessible to anyone who are not authorized to use them. An unauthorized person can cause several problems in the operation of a system, including denying access to legitimate users,...
After all the elements of a computer systemcomputer system have been discovered, they need to be monitored. MonitoringMonitoring of a computer system is defined as the process of obtaining the status and configuration information of the various elements of a computer system and consolidating that information. Information consolidation may involve the tasks of preparing reports to be viewed by an...
Before any operational management of a computer systemcomputer system can be done, applications at the operations center must become aware of the different components of the computer system and the configuration of the different components. Without good discovery mechanisms, the operations center staff will not be able to manage the computing environment effectively.
A computer systemcomputer system consists of many components including hardware devices such as servers, routers, switches, and firewalls and software systems such as the operating system and applications. Each such component allows the operator to change its settings to customize its behavior.
Computer systems and networks are an indispensable component of the modern industry. Regardless of the size of the business, be it a small shop operated by a single family or a large international conglomerate, the profitability of any business operation has a critical dependency upon proper functioning of the computer systems supporting that business. Even on the consumer side, households having...
Computer systems planning and implementation are an essential ingredient for smooth and efficient operation of any computer systemcomputer system . PlanningPlanning is a required prerequisite when installing a new computer system or upgrading an existing computer system to address new requirements. Planning marks the first stage of the life cycle of computer systems. In this chapter, we look at the...
Principles of Computer Systems and Network Management presents the algorithms, architectures, and design techniques for different aspects of system management. The focus of the material is on showing the design principles underlying systems management tools and how concepts from various mathematical domains are applied to better manage computer systems. It is an advanced book for a graduate level...
