Hello Jean-Luc,

Currently it is not possible to get individual values for each Datastore.

We are about to rewrite these Sensors for better performance and after that we will extend it with new features.

Kind regards

We don't measure latency on the VMware host side, but on the storage side. At this moment with a script which runs every 5 minutes on our physical backup server. Output has te be converted to XML. The folder "EVA Performance Monitor" has an alias in IIS on that backup server. In PRTG we have HTTP XML/REST sensors which read the data from the XML files.

f.e. Settings of the sensor >>

URL : http://%servername%/evaperf/hp1ctrl2.xml
XML node : Read_Latency__ms_

( all credits to my colleague who made this )

Maybe you can develop somethink likewise, and post it here ;) For example with esxtop . VMware ESX monitor is an option. I just saw that disk performance monitoring is under development.
