Syslog-protokollan viestien analysointi järjestelmän vianetsinnän apuna
Tietojärjestelmät keräävät toiminnastaan jatkuvasti lokitietoja. Vikatilanteissa lokitietoja voidaan hyödyntää virheen paikantamisen apuna. Lokinkirjoittamisen teollisuusstandardiksi on noussut Syslog-protokolla. Tarve protokollaa varten kehitetyille lokianalyysitekniikoille ja -työkaluille on näin ollen noussut. Tässä kandidaatintutkielmassa pyritään esittelemään näitä analyysitekniikoita ja -työkaluja, ja pohtimaan näiden hyödyllisyyttä järjestelmän vianetsintää suorittavan järjestelmänvalvojan näkökulmasta. Information systems constantly gather operational log data. In case of system failure, this log data can be used as a troubleshooting tool in locating the problem source. The Syslog protocol has become an industry standard in logging. For this reason, a need for log analysis techniques and tools for the protocol has arisen. This bachelor's thesis attempts to introduce these techniques and tools, as well as consider their effectiveness in system troubleshooting from a system administrator's viewpoint.
