Monitor DNS performance and configuration using the DNS Analytics MCP server.

Available Tools

Common Workflows

DNS Health Check

1. Use zones_list to identify zones
2. Use dns_report for each zone to check performance
3. Review metrics for latency, query volume, errors

Configuration Audit

1. Use show_account_dns_settings for account-level settings
2. Use show_zone_dns_settings for zone-specific settings
3. Compare settings across zones for consistency

Performance Investigation

1. Identify the zone with zones_list
2. Pull dns_report for the relevant time frame
3. Analyze query patterns and response times

DNS Report Metrics

The DNS report typically includes:

• Query volume over time
• Response time distribution
• Query types (A, AAAA, CNAME, etc.)
• Response codes (NOERROR, NXDOMAIN, etc.)
• Geographic distribution

Integration with Workers

For Workers using custom domains:

1. Verify zone configuration with show_zone_dns_settings
2. Check DNS report for the zone
3. Correlate with Workers observability data

Troubleshooting

Tips

• Zone IDs from zones_list are needed for other operations
• DNS reports can span custom time ranges
• Account settings may override zone settings
• Use with observability tools for full-stack debugging
