| Abstract | Software components are regularly reused in many large-scale, mission-critical systems where the tolerance for poor performance is quite low. As new components are integrated within an organization's computing infrastructure, it becomes critical to ensure that these components continue to meet the expected quality of service (QoS) requirements. Management instrumentation is an integrated capability of a software system that enables an external entity to assess that system's internals, such as its operational states, execution traces, and various quality attributes during runtime. In this paper, we present an approach that enables the efficient generation, measurement, and assessment of various QoS attributes of software components during runtime using management instrumentation. Monitoring the quality of a component in this fashion has many benefits, including the ability to proactively detect potential QoS-related issues within a component to avoid potentially expensive downtime of the overall environment. The main contributions of our approach consist of three parts: a lightweight component instrumentation framework that transparently generates a pre-defined set of QoS-related diagnostic data when integrated within a component, a method to formally define the health state of a component in terms of the expected QoS set forth by the target environment, and finally a method for publishing the QoS-related diagnostic data during runtime so that an external entity can measure the current health of a component and take appropriate actions. The main QoS types that we consider are: performance, reliability, availability, throughput, and resource usage. Experimentation results show that our approach can be efficiently utilized in large mission-critical systems |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
