Characterizing Direct Monitoring Techniques in Software Systems

摘要: Monitoring is a consolidated practice to characterize the dependability behavior of software system. A variety techniques, such as event logging and operating system probes, are currently used generate monitoring data for troubleshooting failure analysis. In spite importance monitoring, whose role can be essential in critical systems, there lack studies addressing assessment comparison techniques aiming monitor occurrence failures during operations. This paper proposes method implemented The based on fault injection approach allows measuring 1) precision recall technique 2) dissimilarity it generates upon failures. has been two systems implementing logging, assertion checking, source code instrumentation techniques. We analyzed total 3 844 With respect our data, we observed that effectiveness strongly affected by type failure, combination different potentially beneficial increase overall reporting ability. More important, analysis revealed number practical implications taken into account when developing technique.
