Issue/Introduction

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

 

 

Environment

  • Release: 20.4.x
  • probe: vmware

Resolution

vmware probe is using the below two values via vmware api.

https://<ip address of esxi>/mob/?moid=ha-host&doPath=summary%2equickStats

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.
