Abstract:
1. A method of monitoring one or more devices forming an information processing system, the method comprising the steps, executed by an information apparatus communicatively coupled to the one or more devices, of: acquiring, from each of the devices, resource information that is information related to resources of the device, and monitoring, on the basis of the acquired resource information, an operation state of the device set as a target to be always monitored; managing each of the devices by setting the device to be in any one of monitoring states including a monitoring target being the target to be always monitored, a semi-monitoring target not being the target to be always monitored but being a target to be determined whether or not there is a change in the resources of the device, and a non-monitoring target being neither the monitoring target nor the semi-monitoring target; storing information indicating a current monitoring state of each of the devices among the monitoring states; storing the resource information acquired from each of the devices last time; newly acquiring the resource information on the device from the device whose monitoring state is currently set to be the semi-monitoring state, and determining whether or not there is a change in the resources of the device on the basis of the newly acquired resource information, the resource information acquired and stored last time, and a previously stored determination condition; and outputting information prompting a change of the monitoring state of the device if it is determined in the determination step that there is a change in the resources of the device.
