Availability
The availability of a complex system such as an ESXi host is not a simple binary. There is degradation, which is important to distinguish to help manage in large farm.
Implementation using VCF Operations super metric:
What are the limitations of the above?
Yes, it does not recognise the sub-degradation in a fully functioning ESXi. VMs running on an ESXi are unlikely to experience any performance degradation as the hardware has redundancy on network card, storage HBA, local disks, fan, and power supply. ESXi can also lose the iLO network as it’s a separate network.
