i want to get memory usage from Mi (megabytes) not the Ki. Please help me!
This unit is hardcoded in official kube-state-metrics code which shouldn't be changed. For example node metrics - especially memory usage is in Megabytes unit not Kilobytes.
To get memory usage of specific pod in Megabytes units simply execute:
kubectl top pod --namespace example-app
NAME CPU(cores) MEMORY(bytes)
app-deployment-76bf4969df-65wmd 12m 1Mi
app-deployment-76bf4969df-mmqvt 16m 1Mi The
kubectl topcommand returns current CPU and memory usage for a cluster’s pods or nodes, or for a particular pod or node if specified.
You can also convert received value:
1 KB = 0.001 MB (in decimal),
1 KB = 0.0009765625 MB (in binary)Take a look: kube-state-metrics-monitoring.
