Use this Knowledge Script to monitor the following AXFR (zone transfer, a database replication mechanism) statistics for Master and Secondary Domain Name System (DNS) servers:
AXFR Request Received (Master)

AXFR Success Received (Secondary)
This script monitors changes to these statistics since the last interval (delta value), and raises an event if a monitored value exceeds the threshold you set. If you collect data with this script, the AXFR statistics are returned as separate datastreams.
