Abstract

A method is provided for monitoring devices with changing IP addresses. SNMP trap is received from a device at a first IP address to notify that a connection is up, and a SNMP poll is transmitted to the device to obtain an identifier. Predetermined consecutive SNMP GET requests are transmitted to the device in intervals. Responsive to failing to receive from the device predetermined consecutive SNMP GET responses equal to the predetermined consecutive SNMP GET requests, it is determined that there is a connection failure or a device failure and checked whether the device is in a maintenance window. If not in maintenance window, a trouble ticket is generated. Responsive to the failure, there is a predetermined waiting period for another SNMP trap from the device with a second IP address and the same identifier notifying that a connection is back up, and no trouble ticket is generated.
