摘要:

服务器集群是许多需要高可用性、可扩展性和更容易管理其基础设施的组织所采用的常见设计原则。服务器通常根据它们提供的服务进行集群,无论是安装的应用程序、服务器的角色还是服务器的可访问性。为了优化性能、管理负载和保持可用性,服务器可能从一个集群组迁移到另一个集群组,使得服务器监视工具难以连续监视这些动态变化的组。服务器监控工具通常是静态配置的,并且组成员的任何更改都需要手动重新配置;在大规模云基础设施上执行这一任务是不合理的。在本文中,我们提出了Cloudlet控制和管理系统(C2MS);用于监视和控制云基础设施内的物理或虚拟服务器的动态组的系统。C2MS扩展了Ganglia -一个开源的可扩展系统性能监控工具-允许系统管理员定义,监控和修改服务器组,而无需重新配置服务器。反过来,管理员可以轻松地监控大规模动态云基础设施上的组和单个服务器指标,其中服务器的角色可能会频繁更改。此外,我们补充组监控与控制元素,允许管理员指定的操作,以执行服务组内的服务器,以及引入进一步的自定义监控指标。本文概述了C2MS的设计,实施和评估。

英文摘要:

Server clustering is a common design principle employed by many organisations who require high availability, scalability and easier management of their infrastructure. Servers are typically clustered according to the service they provide whether it be the application(s) installed, the role of the server or server accessibility for example. In order to optimize performance, manage load and maintain availability, servers may migrate from one cluster group to another making it difficult for server monitoring tools to continuously monitor these dynamically changing groups. Server monitoring tools are usually statically configured and with any change of group membership requires manual reconfiguration; an unreasonable task to undertake on large-scale cloud infrastructures. In this paper we present the Cloudlet Control and Management System (C2MS); a system for monitoring and controlling dynamic groups of physical or virtual servers within cloud infrastructures. The C2MS extends Ganglia - an open source scalable system performance monitoring tool - by allowing system administrators to define, monitor and modify server groups without the need for server reconfiguration. In turn administrators can easily monitor group and individual server metrics on large-scale dynamic cloud infrastructures where roles of servers may change frequently. Furthermore, we complement group monitoring with a control element allowing administrator-specified actions to be performed over servers within service groups as well as introduce further customized monitoring metrics. This paper outlines the design, implementation and evaluation of the C2MS.
