A monitoring system, comprising:

• a plurality of image capturing devices that capture images of a plurality of monitoring target devices;
• output devices that output operation information of the plurality of monitoring target devices;
• a display device that displays information;
• a control device that controls the display device;
• and
• a storage device that stores information;
• wherein the storage device stores, in an associated manner, image capturing information obtained in image capturing of each of the plurality of image capturing devices, image capturing time information indicating the time when the image capturing information was captured, and identification information of the monitoring target devices for which the image capturing information was captured, and the storage device also storing, in an associated manner, the operation information output by each of the plurality of output devices, operation time information indicating the time when the operation information was obtained, and identification information of the monitoring target devices related to the operation information;
• and
• wherein the control device, when an abnormality has occurred in any of the plurality of monitoring target devices, executes a first display control that causes the display device to display abnormality occurrence information including at least identification information of the monitoring target device in which the abnormality has occurred and occurrence time information indicating the time when the abnormality occurred;
• and
• wherein the control device, when one item, or one item among two or more items, of the abnormality occurrence information displayed in the display device has been selected, executes a second display control that acquires the image capturing information of the monitoring target device corresponding to the selected abnormality occurrence information from the storage device and causes the display device to display the acquired image capturing information, and executes a third display control that acquires the operation information of the monitoring target device corresponding to the selected abnormality occurrence information from the storage device and causes the display device to display the acquired operation information.
