Isilon OneFS: Seznam hodnot Isilon Audit Payload

Následuje seznam možných hodnot Isilon, které lze vidět v hrubých výstupech isi_audit Výsledky.

Tento výpis není specifický pro verzi. Některé z těchto kódů existují pouze v určitých verzích systému OneFS. Novější verze systému OneFS mají rozšířené možnosti; Tento článek obsahuje seznam všech datových částí auditu ve všech verzích. Tento seznam má sloužit jako reference při kontrole jednotlivých událostí auditu obecně.

Audit může monitorovat a sledovat akce účtů připojených k systému souborů OneFS v protokolech, jako jsou SMB a NFS.

Akce zaznamenané v nezpracované podobě vypadají takto (mezi verzemi a érami systému OneFS dochází k určitým odchylkám):
