With IPHost Network Monitor you can run WMI Availability monitoring of various devices in your network.
To create a WMI monitor for Availability, provide host name (it must be a Windows host) and specify custom WQL query:
The availability and status of the device. For example, the Availability property indicates that the device is running and has full power (value=3), or is in a warning (4), test (5), degraded (10) or power save state (values 13-15 and 17). Regarding the power saving states, these are defined as follows: Value 13 ("Power Save - Unknown") indicates that the device is known to be in a power save mode, but its exact status in this mode is unknown; 14 ("Power Save - Low Power Mode") indicates that the device is in a power save state but still functioning, and may exhibit degraded performance; 15 ("Power Save - Standby") describes that the device is not functioning but could be brought to full power 'quickly'; and value 17 ("Power Save - Warning") indicates that the device is in a warning state, though also in a power save mode.
The Win32_SerialPort class represents a serial port on a Win32 system.
