PRTG version 9.2 released
01/24/2012

PRTG's VMware sensors now support vSphere 5, so you can now monitor ESX(i) 5 hosts, virtual machines, and vCenter 5. Virtual machines that are located within vApps can now be monitored, as well. They also added a new "WMI UTC Time Sensor" which can measure the time difference between a Windows target machine and the PRTG system time, so you can be alerted if a client is on the wrong time.
