Use this Knowledge Script to monitor the number of Domain Name Service (DNS) dynamic update errors. This script checks for two types of errors:
Dynamic updates rejected by the DNS server
Dynamic update timeouts of the DNS server
This script raises an event if the number of dynamic update errors in the interval exceeds the threshold you set.
The dynamic update mechanism allows clients and servers to register DNS domain names and IP address mappings to a DNS server.
