• Discovery läuft Regelmässig durch das ganze Netz • Es kann bestimmt werden, was wann ausgelesen wird • Policies bestimmen, was wichtig ist und was nicht • Aktionen können automatisch ausgelöst werden

• Monitoring überprüft nur, ob Ziele noch leben • Erlaubt zusätzlich granulare Schwellwerte

• Events (Discovery, Syslog, Traps und Monitoring) werden Zentral gesammelt und ausgewertet
