I tried the memory "averageUtilization" values with 1.5Gi and "1.5Gi" with double quotes. Can anyone check and let me know if I am missing something here?

averageUtilization:

is represented as a percent of requested memory. So you're wrong with Mi.

It should be.

averageUtilization: 65

Specify averageUtilization and a target average memory utilization over all the pods, represented as a percent of requested memory. The target pods must have memory requests configured.

    Thanks. https://access.redhat.com/documentation/en-us/openshift_container_platform/4.5/pdf/nodes/openshift_container_platform-4.5-nodes-en-us.pdf Page-31 in this link was also mentioning the same. Appreciate your help! – Arun Prakash Nagendran Aug 18 '22 at 04:11
  • If I use the actual value, then I can provide the actual value. target: type: AverageValue 10 averageValue: 500Mi – Arun Prakash Nagendran Aug 18 '22 at 04:13
