VMware kept their promise: It is Q3 now and a patch for the slow hardware status bug has been released.
The patch was released on July 12th and can be downloaded here: http://kb.vmware.com/kb/2019107.
It is strongly recommended to install this patch. Not only will check_esxi_hardware.py work smooth as before again, but also will you access your hardware status in vSphere client much faster again.

Tested against an ESXi 4.1 box, OK.
Upgraded it to ESXi 5.1, still OK.
Installed Dell OpenManage 7.1, still OK.

Hi Dave, I cannot confirm this. I received feedback from other check_esxi_hardware users already monitoring ESXi 5.1 hosts (Dell too).

Been using you plugin for about 2 years, love it! Thought you may like to know, VMware just released ESXi 5.1 and looks like the slow hardware status is back. Although I am only trying on a mix of Dell Servers.
