An Evaluation of Log File & Compression Mechanism

Abstract: - with worldwide development of multi-national company's communication infrastructure required to increase. As the size of these computer networks increases, it becomes more and more difficult to monitor, control, and secure them. Networks consist of a number of diverse devices, sensors, and each of these devices produces log files, which need to be analyzed and monitored to provide network security and satisfy regulations. current information systems are replete with log files, created in multiple places (e.g., network servers, database management systems, user monitoring applications, system services and utilities) for multiple purposes (e.g., maintenance, security issues, traffic analysis, legal requirements, software debugging, customer management, user interface usability studies). Log files in complex systems may quickly grow to huge sizes. Often, they must be kept for long periods of time. For reasons of convenience and storage economy, log files should be compressed. However, most of the available log file compression tools take advantage of redundancy algorithms (e.g., Deflate) which do not take advantage of purpose-specific for log files. Presented paper describes an optimal framework for log-file compression.
