DNS
What this example does
DNS infrastructure verification: DNS stable assertion ID severity rules. It helps detect resolution, delegation or published-record problems.
Checks and behavior
- Queries DNS records or resolver behavior ([{'type': 'A', 'exists': True, 'min_ttl': 30, 'max_response_time': 1.0}]).
- Formats results for nagios output.
Adapt example domains, addresses, credentials and thresholds to your environment before use.
