Fixed In Version: 5.6.2.0 Doc Type: Bug Fix
Doc Text:
Previously, CPU right-size recommendations only reported CPU sockets, not cores per socket. This caused CPU right-size recommendations to incorrectly report a virtual machine with 1 socket and 4 cores as having 1 total CPU. This has been fixed in the code that calculates right-size recommendations, which now uses the cpu_total_cores value to instead of num_cpu to correctly report the total number of logical CPUs.
