=head1 MODE

Monitor the power consumption of VMware ESX hosts through vSphere 8 REST API.

    Meaning of the available counters in the VMware API:
    - power.capacity.usable.HOST      Current maximum allowed power usage.
    - power.capacity.usage.HOST       Current power usage.
    - power.capacity.usagePct.HOST    Current power usage as a percentage of maximum allowed power.
    
Since our tests showed that only C<power.capacity.usage.HOST> was different from zero, the other counters are ignored at the moment.
