Data collecting apparatus and gateway apparatus

This invention intends to provide a data collecting apparatus and a gateway apparatus capable of reducing the labor for setting the threshold value or condition used for a real running point, reducing the number of cases where the threshold value or condition is erroneously set and setting the threshold value or condition within a narrow range.The data collecting apparatus includes device value collecting unit for collecting device values from a plurality of devices, abnormal state storage unit for storing the monitored device to be monitored and the threshold value or condition by which it is determined that the monitored device is abnormal, abnormal state confirming unit for comparing the device values of the plurality of devices with the threshold value or condition by which it is determined that the monitored device is abnormal, determining whether or not the device is abnormal and if abnormal, sending the information that the monitored device is abnormal to a host managing device, device feature information detecting unit for detecting the feature information from device value collected by the device value collecting unit and abnormal state editing unit for editing the threshold value or condition by which it is determined that the monitored device is abnormal, stored in the abnormal state storage unit , using the feature information detected.
