Abstract: A monitoring system detects a deviation in a monitoring metric of a system component of a remote management system that remotely manages image forming apparatuses. When the monitoring system detects a deviation in online device count greater than or equal to a deviation threshold and makes a determination that there is a correlation between the deviations in monitoring metrics of multiple system components as detected, the monitoring system sends a failure report indicating that a failure is in the remote management system.
