It’s always a good idea to monitor your hardware’s sensor and temperatures and VSAX helps you keep a close eye on them.
You can configure your temperature unit of measure in the "Server Admin > Endpoint Policies > System > General" section of the Web App.
You can also configure this setting on the VSAX Agent itself. However, the Web App Policy settings (if applied to the same machine) will always take precedence over the individual agent settings.
Also, Policies are naturally more convenient for applying such monitoring rules, as they can be applied to multiple machines simultaneously.
To configure this setting on the Agent, go to the "System > General" tab.
