| Abstract | A software agent is defined as an autonomous software entity that can interact with its environment. It is capable of responding to other agent and/or its environment to some degree. It has some degree of control over its internal state and actions based on its own model. The behavior of an agent has been described by BDI theory as a processing cycle. According to this theory we have developed the processing cycle with software feedback mechanism. Software feedback or loop-back control mechanism is capable acting without direct external intervention. A feedback mechanism continuously monitors the output of the system under control (the target system), compares the result against preset values (goals of the feedback control) and feeds the difference back to adjust the behavior of the target system in one processing cycle. This paper considers the modeling and design of a monitor agent with layered control architecture for autonomy and adaptation. The architecture consists three layers: schedule layer, optimization layer and regulator layer. The regulator layer utilizes software feedback and control methods in a process cycle, the optimization layer will help to adapt to the changing environment more precisely, the schedule layer generates the long-term goal for the agent. Also this paper gives a example of the agent for monitoring the mail server running Lotus Notes. Such sort of computing systems typically have two competitive control goals, namely: maximization of the throughput and minimization of the response time. A set of experimental results showing the effectiveness of the monitor agent for email server has been presented. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
