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.
