Health monitoring state. ## system/health **Conditions:** !i386 **Syscap:** health **Type:** Directory Hardware health monitoring on non-x86 devices. Use `/system/health/print` to list the name, current value and type of each monitored parameter. Name of the monitored parameter, for example `voltage`, `cpu-temperature` or `fan1-speed`. Current value of the parameter. The value and its unit depend on the parameter `type`. Type of the measured value: `C` is degrees Celsius, `RPM` is fan speed, `V` is voltage, `A` is current and `W` is power consumption.
