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 data center. For more information, see http://www.dmtf.org/standards/smash.
You can monitor host health status either by connecting the vSphere Client directly to a host, or by
connecting the vSphere Web Client to a vCenter Server system. You can also set alarms to trigger when the
host health status changes.
NOTE The interpretation of hardware monitoring information is specific for each hardware vendor. Your
hardware vendor can help you understand the results of the host hardware components monitoring.
Monitor Health Status When Directly Connected to a Host
When you connect the vSphere Client directly to a host, you can view the health status from the host’s
Configuration tab.
Prerequisites
Required privilege: Host.Configuration.Advanced Configuration
Procedure
1 Log in to the host using the vSphere Client, and display the inventory.
2 Click the Configuration tab, and click Health Status.
If a component is functioning normally, the status indicator is green. The status indicator changes to yellow
or red if a system component violates a performance threshold or is not functioning properly. Generally, a
yellow indicator signifies degraded performance. A red indicator signifies that a component stopped
operating or exceeded the highest threshold. If the status is blank, then the health monitoring service cannot
determine the status of the component.
The Reading column displays the current values for the sensors. For instance, the column displays rotations
per minute (RPM) for fans and degrees Celsius for temperature.
