Um die Systemverfügbarkeit und Leistung zu maximieren, verwendet eLabNext Zabbix, um den Zustand und die Anwendungsverfügbarkeit der Private Cloud-Installation kontinuierlich zu überwachen.
Im Falle einer Nichtverfügbarkeit oder Unregelmäßigkeiten des Systems werden unsere Systemtechniker automatisch benachrichtigt, um das Problem zu lösen und eine Eskalation zu vermeiden. Alle Ereignisse auf dem Server werden automatisch protokolliert.
