The hardware vendors may ask you to check the health status of an ESXi host without pointing out any specific problems of vSphere.
For checking the general health status of ESXi hosts, check below in vSphere Client:
- Target ESXi host > Monitor > Issues and Alarms > All Issues
- Target ESXi host > Monitor > Issues and Alarms > Triggered Alarms
If there are any issues reported or triggered alarms, search them in Broadcom KB, or contact Broadcom VCF Support.
