HP Monitoring ESXi 5.1

Hi,

I have an HP DL380 G5 running ESXi 5.1.0 and all I really want to do it to get an email alert if one of the disks in the array fails or if a PSU fails.  I have read so many posts about this but none seem to give me a solution.

I have read some that mention vCenter Server and some which mention HP SIM.  I don’t want to have to pay for any software.  Can anyone suggest the simplest method to do this?

Thanks
