Über Log-Analyse

Die Analyse von Log-Dateien ist essentiell für:

Fehlersuche – Identifikation von ERROR- und WARNING-Meldungen
Sicherheit – Erkennung von Angriffsmustern (404-Floods, brute-force)
Performance – Analyse von Zugriffszeiten und Serverauslastung
Monitoring – Überwachung von Systemereignissen
Reporting – Erstellung von Statistiken für Management und Kunden
