| Abstract | Our main aim is to extract multiple rules from log files in the computer systems, to detect various levels of errors, and to inform these errors or configuration mistakes to the system administrators automatically, in order to manage them without expert knowledge. To satisfy this aim, we performed an extraction experiment from the log files of a system using Automatically Defined Groups (ADG), which is based on Genetic Programming. Moreover, we focused on "System State Pattern" related to the difference between normal daily state and abnormal state that some errors occur in the system. In this experiment, then, we tried to extract rules without any manually managed and supervised information, by using simple translation technique: regular expressions. As a result, 50 agents in the best individual were divided into 16 groups from 322 log files. This means that 16 rules were acquired. We confirmed these rules could detect some errors such as DNS configuration error. We could also find the importance of the rules because the rule with more agents tended to have a higher adopted frequency by evolutionary computation. Therefore, we consider that our method using ADG is useful for the diagnosis of computer systems, and helps administrators manage their systems without expert knowledge about their 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.
