Compare recursive resolvers

66-dns-nameserver-compare.yaml

DNS

What this example does

DNS infrastructure verification: Compare recursive resolvers. It helps detect resolution, delegation or published-record problems.

Checks and behavior

  • Queries DNS records or resolver behavior ([{'type': 'A', 'min_count': 1, 'max_response_time': 2.0}]).
  • Formats results for icinga2 output.

Adapt example domains, addresses, credentials and thresholds to your environment before use.
