Network management system with a switchable flood revention mode pregarding fault events for a managed device

摘要

A network management system comprises a server connected to a plurality of probes, each probe connected to one or more managed devices. A method of operating the system comprises the steps of receiving fault events for the managed devices at the probes, detecting that the rate of received fault events has reached or is approaching an overload level for the server, identifying a managed device contributing to the reached or approached overload level, switching the probe for the identified managed device to a flood prevention mode, and operating the switched probe in the flood prevention mode thereby combining multiple fault events for the identified managed device into a single fault event for transmission to the server.
