- 1000m (milicores) = 1 core = 1 vCPU = 1 AWS vCPU = 1 GCP Core.
- 100m (milicores) = 0.1 core = 0.1 vCPU = 0.1 AWS vCPU = 0.1 GCP Core.
- 8000m = 8 cores = 8 vCPUs
CPU(cores) 338m means 338 millicpu. 1000m is equal to 1 CPU, hence 338m means 33.8% of 1 CPU. CPU% It is displayed only for nodes, and it stands for the total CPU usage percentage of that node. Memory Memory being used by that node Memory% It is also displayed only for nodes, and it stands for total memory usage percentage of that node.
