Why "top" command shows cpu usage above 100% ?
Issue
- The VM is assiged 4 vCPUs.
- How do to read the information when “top” command is run.
- Is the %CPU for the top CPU, eg
derived from Cpu0, Cpu1, Cpu2, and Cpu3? - Since 4 CPUs now and each can reach 100%, is it safe to say that the server will only consider peak when this number reaches
400%? it is very common to notice the %CPU to shoot above 150-200%.
