Cacti ist ein Netzwerk-Monitoring-Tool, das speziell für die Verwaltung von Netzwerk-Latencies, Bandbreiten und Paketverlusten entworfen wurde, wobei er eine grafische Benutzeroberfläche bietet, um die erfassten Daten zu visualisieren. Es kann in verschiedenen Umgebungen eingesetzt werden, um die Netzwerkperformance zu überwachen und Probleme zu diagnostizieren
