According to the above-described configuration, the status of the monitoring object equipment can be diagnosed and visualized for the sake of the condition based maintenance to perform maintenance in accordance with the status of each equipment. ## Claims ### Claim 1 A monitoring system comprising: a monitoring object equipment, which is an industrial equipment configured to transmit data including a parameter indicating a physical condition of the monitoring object equipment including one or more of a temperature, a current, and a pressure; a server configured to receive the data transmitted by the monitoring object equipment, the server including a hardware processor and a non-transitory computer-readable medium storing a program with instructions that cause the hardware processor to: receive, from the monitoring object equipment, equipment identifying information for identifying the monitoring object equipment and an analysis purpose, which includes the parameter indicating the physical condition of the monitoring object equipment; and output a tendency of an analysis item data compared with predetermined comparison item data; wherein the analysis item data, which has a value within a specified range and is selected from among operation data indicating an operating status of the monitoring object equipment, corresponds to the parameter indicating the physical condition of the monitoring object equipment; wherein the specified range is based on the equipment identifying information and the analysis purpose which have been input; wherein the comparison item data is data which is of a type different from that of the analysis item data and has a correlation with the analysis item data; and wherein when the analysis item data is an internal equipment temperature of the monitoring object equipment, a surrounding air temperature is used as the comparison item data. ### Claim 2 (depends on 1) The monitoring system according to claim 1, wherein the specified range is included in a range that does not satisfy a condition for anomaly detection regarding relevant item data. ### Claim 3 (depends on 1) The monitoring system according to claim 1, wherein the instructions further cause the hardware processor to generate comment data for reporting the operating status of the monitoring object equipment and illustrate a report including the comment data on a display screen. ### Claim 4 (depends on 3) The monitoring system according to claim 3, wherein the specified range is included in a range that does not satisfy a condition for anomaly detection regarding relevant item data; and wherein if there is an actual result which satisfies the condition for the anomaly detection during a target period of the report, the data visualization unit generates the comment data for reporting the actual result of the anomaly detection; and if there is no actual result which satisfies the condition for the anomaly detection during the target period of the report, the data visualization unit generates the comment data for reporting the tendency of the analysis item data. ### Claim 5 (depends on 1) The monitoring system according to claim 1, wherein the comparison item data is acquired under an environment different from that of the analysis item data. ### Claim 6 (depends on 5) The monitoring system according to claim 5, wherein the comparison item data was acquired in past regarding the monitoring object equipment. ### Claim 7 (depends on 5) The monitoring system according to claim 5, wherein the comparison item data is acquired regarding equipment of a same machine type as that of the monitoring object equipment. ### Claim 8 (depends on 5) The monitoring system according to claim 5, wherein the comparison item data is acquired regarding equipment of a same area as that of the monitoring object equipment. ### Claim 9 A monitoring apparatus comprising: a hardware processor configured to receive data from a monitoring object equipment, which is an industrial equipment, the data including a parameter indicating a physical condition of the monitoring object equipment including one or more of a temperature, a current, and a pressure; and a non-transitory computer-readable medium storing a program with instructions that cause the hardware processor to: receive equipment identifying information for identifying the monitoring object equipment and an analysis purpose, which includes the parameter indicating the physical condition of the monitoring object equipment; and output a tendency of an analysis item data compared with predetermined comparison item data; wherein the analysis item data, which has a value within a specified range and is selected from among operation data indicating an operating status of the monitoring object equipment, corresponds to the parameter indicating the physical condition of the monitoring object equipment; wherein the specified range is based on the equipment identifying information and the analysis purpose which have been input; wherein the comparison item data is data which is of a type different from that of the analysis item data and has a correlation with the analysis item data; and wherein when the analysis item data is an internal equipment temperature of the monitoring object equipment, a surrounding air temperature is used as the comparison item data. ### Claim 10 A monitoring method comprising: receiving equipment identifying information for identifying monitoring object equipment, which is an industrial equipment, and an analysis purpose, which includes a parameter indicating a physical condition of the monitoring object equipment including one or more of a temperature, a current, and a pressure; determining whether an analysis item data has a value within a specified range, and determining comparison item data to be used for a comparison with the analysis item data; and outputting, for the analysis item data that has the value within the specified range, a tendency of the analysis item data compared with the comparison item data; wherein the analysis item data is selected from among operation data indicating an operating status of the monitoring object equipment, and the analysis item data corresponds to the parameter indicating the physical condition of the monitoring object equipment; wherein the specified range is based on the equipment identifying information and the analysis purpose which have been input; wherein the comparison item data is data which is of a type different from that of the analysis item data and has a correlation with the analysis item data; and wherein when the analysis item data is an internal equipment temperature of the monitoring object equipment, a surrounding air temperature is used as the comparison item data.
