12th International Symposium on Software Reliability Engineering (ISSRE'01)
Measurement-Based Availability of Unix Systems in a Distributed Environment
Hong Kong, China
November 27-November 30
ISBN: 0-7695-1306-9
This paper presents a measurement-based availability study of networked Unix systems, based on data collected during 11 months from 298 workstations and servers interconnected through a local area computing network. The data corresponds to event logs recorded by the Unix operating system via the Syslogd daemon. Our study focuses on the identification of machine reboots and the evaluation of statistical measures characterizing: a) the distribution of reboots (per machine,time), b) the distribution of uptimes and downtimes associated to these reboots,c) the availability of machines including workstations and servers, and d) error dependencies between clients and servers.
