We have found that VM maximum memory Utilization is more then 100% for some hosts
"Qos_Memory_perc_usage" is the vmware probe qos which is giving high memory utilization data
vmware probe is using the below two values via vmware api.

We can see "overallMemoryUsage" value here.
https://<ip address of esxi>/mob/?moid=ha-host&doPath=summary%2ehardware
We can see "memorySize" value here.
We divide "overallMemoryUsage" by "memorySize".
The probable cause is - "overallMemoryUsage" is larger than "memorySize".
Note:
"overallMemoryUsage" counter is MBytes
"memorySize" counter is Bytes
so we convert "memorySize" into MBytes format, then divide.
