Hallo, in einem Netz bricht zwischendruch alles komplett zusammen. Die Switche werden regelrecht mit Paketen überflutet. Mittels OMD und check_mk habe ich jetzt einen Server ausgemacht der zum Zeitpunkt der Störung eine auffällig hohe CPU-Last zeigt. Passend finde ich in /var/log messages und warn reihenweise unten aufgeführte Einträge. Die Hardware ist jat 4 Jahre alt und läuft seit Jahren auch mit den gleichen Anwendungen/ Prozessen. Aus dem Bauch heraus würde ich sagen das System fängt an morsch zu werden und sollte auf neuere Hardware umziehen. Leider kann mein Monitoring nicht alle laufenden Prozesse permanent mitprüfen. Gibt es ein Tool das ich nutzen könnte um so raus zu bekommen welcher Prozess ggf. auf hohe Last geht indem ich alle Prozesse mitschreibe?
