You can use the vSphere Client or the vSphere Web Client to monitor the state of host hardware components, such as CPU processors, memory, fans, and other components.
The host health monitoring tool allows you to monitor the health of a variety of host hardware components including:
The host health monitoring tool presents data gathered using Systems Management Architecture for Server Hardware (SMASH) profiles. The information displayed depends on the sensors available on your server hardware. SMASH is an industry standard specification providing protocols for managing a variety of systems in the datacenter. For more information, see http://www.dmtf.org/standards/smash.
You can monitor a host’s health status either by connecting the vSphere Client directly to a host, or by connecting to a vCenter Server system. You can also set alarms to trigger when the host health status changes.
