Problems with hardware monitoring with HP/Dell servers and latest ESXi builds

Hey guys,

I'm having problems recently with the hardware monitoring tab on vCenter with both HP and Dell server since the 5.1 build 799xxx onwards. I'm now testing 1065491 and I can't get hardware monitoring on the servers with the latest vCenter virtual appliance installed from a new OVA template. This is being quite annoying as I can't get the monitoring software I use called PRTG to check any hardware status from the servers and this is turning out to be a massive headache.

Have you guys had any luck with the latest builds and hardware monitoring on Dell and HP servers so far?

Thanks!
