| Abstract | In this paper, we introduce the new technique of high-confidence software monitoring (HCSM), which allows one to perform software monitoring with bounded overhead and concomitantly achieve high confidence in the observed error rates. HCSM is formally grounded in the theory of supervisory control of finite-state automata: overhead is controlled, while maximizing confidence, by disabling interrupts generated by the events being monitored - and hence avoiding the overhead associated with processing these interrupts - for as short a time as possible under the constraint of a user-supplied target overhead Otarget. HCSM is a general technique for software monitoring in that HCSM-based instrumentation can be attached at any system interface or API. A generic controller implements the optimal control strategy described above. As a proof of concept, and as a practical framework for software monitoring, we have implemented HCSM-based monitoring for both bounds checking and memory leak detection. We have further conducted an extensive evaluation of HCSM's performance on several real-world applications, including the Lighttpd Web server, and a number of special-purpose micro-benchmarks. Our results demonstrate how confidence grows in a monotonically increasing fashion with the target overhead, and that tight confidence intervals can be obtained for each target-overhead level. |

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.
