Comprehensive and Detailed Explanation From Exact Extract:
When troubleshooting high CPU usage on the SDDC Manager VM, the recommended diagnostic steps are:
Login to SDDC Manager using console with root credentials, run the top command to identify any services that may be consuming high %CPU (B):The official documentation instructs administrators to use system monitoring commands such as top or htop within the SDDC Manager appliance to determine if specific processes or services are causing elevated CPU usage. This helps pinpoint the root cause inside the VM.
Review the CPU usage of the ESXi management domain hosts to identify any that are overcommitted (D):High CPU usage within the SDDC Manager VM could also result from overall CPU contention on the physical ESXi hosts. Checking host-level CPU usage can help determine if the underlying infrastructure is contributing to the performance issue. The documentation emphasizes reviewing host resource metrics to ensure the management cluster is not overcommitted.
Other options such as rebooting the VM, upgrading vSphere, or modifying DRS settings are not recommended as initial diagnostic steps according to official guidance. Rebooting or changing configurations without proper analysis may disrupt services or not address the root cause.
