For example, a given device may have several voltage sensors as well as temperature sensors each with appropriate threshold support to help NMS systems detect and alert appropriately. In addition, on systems where it is supported, if the sensor value crosses the supported threshold value the system can generate appropriate notification as well."

A value of 'disabled' means the resource is totally inoperable. A value of 'enabled' means the resource is partially or fully operable. A value of 'testing' means the resource is currently being tested and cannot therefore report whether it is operational or not. A value of 'unknown' means that this resource is unable to report operational state. A value of 'notInstalled' means the resource is not physically present."
