  • Fixed Default DNSMonitor template uses ${dev/id} rather than ${dev/manageIP} for the DNS Server field (ZEN-29750)
  • Fixed DNS server connection refusal triggers a python error, no event generated (ZEN-29751)


  • Rewrote ZenPack to use twisted.names Python library instead of Nagios check_dns plugin
