EVA Monitoring via Evaperf & Windows Perfom.msc

Hallo,
ich habe ein Monitoring unserer Eva4400 eingerichtet. Die gelieferten Werte von Evaperf und Perfmon.msc unterscheiden sich sehr stark z.B. (siehe Screenshot):
Evaperf: Write MB/S 35,7 MB/s
Perfmon: Wrtie KB/s 786,3 KB/s

Die Perfmon Optionen werden ja durch die Installation der HP Tools erweitert und somit hat man Zugriff auf die EVA Werte.
Hat jemand Erfahrungen damit und kann mir sagen wodurch diese Differenzen entstehen.

Hi,
I have set up a monitoring our EVA4400. The values supplied by EVAPerf and Perfmon.msc differ as greatly (see screenshot):
EVAPerf: Write MB / s 35.7 MB / s
Perfmon: Wrtie KB / s 786.3 KB / s

The Perfmon options are indeed enhanced by the installation of the HP tools and thus one has access to the EVA values.
Does anyone have experience with it and can tell me which caused these differences.

Ah okay, now I see it.

But the evaperf is listing the speed on the host ports, not the activity on the disk groups.

Maybe it is a lot less on the disk groups because most of what is read/written is from the cache?
