DNS two resolvers with retries

86-dns-multi-backend-retry.yaml

DNS

What this example does

Multi-node infrastructure verification: DNS two resolvers with retries. This can reveal differences between individual service backends.

Checks and behavior

  • Queries DNS records or resolver behavior ([{'type': 'NS', 'exists': True}]).
  • Runs against explicitly configured backends.
  • Retries failures to reduce transient false alarms.
  • Formats results for nagios output.

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