Sissejuhatus
Syslog
Syslog on utiliit, mis genereerib logifailid ning saadab need Linxi süsteemi logifaili, mis asub /var/log/ kaustas, kus neid omakorda analüüsitakse. Syslog'i teateid saadavad välja erinevad võrguseadmed: ruuterid, switchid jms. Syslog'i teated sisaldavad tavaliselt informatsiooni: kus, millal ja miks teade saadeti.
Facility
The Facility value is a way of determining which process of the machine created the message. Since the Syslog protocol was originally written on BSD Unix, the Facilities reflect the names of Unix processes and Daemons. The priority value is calculated using the following formula: Priority = Facility * 8 + Level
