3ware Raid Controller IOPs Linux cli

3ware Raid Controller IOPs

nach Jahren ist mir aufgefallen das man über die 3Ware tw_cli auch die IOPs auslesen kann wenn man das aktiviert.

zum aktivieren der Statistik gibt man folgenden Befehl ein.

[stextbox id=“bash“]tw_cli /c0 set dpmstat=on[/stextbox]

Setting Drive Performance Monitoring on /c0 to [on] ... Done.

Zum anzeigen der IOPs nutzt man dann diese befehle

Derzeitige IOPs (ist die default Ausgabe)

[stextbox id=“bash“]tw_cli /c0 show dpmstat[/stextbox]
