NAv2 node reference

​​ Main nodes

Main nodes provide deep packet-level information about traffic and attacks for Spectrum customers and Magic Transit customers.

Use the main node to query traffic and attacks at a high level, as seen at the Cloudflare edge:

ProductMain node
SpectrumspectrumNetworkAnalyticsAdaptiveGroups
Magic TransitmagicTransitNetworkAnalyticsAdaptiveGroups

To query more specific details about attacks, use the attack nodes.

Each row represents a packet sample. The sample rate of main nodes is 1/10,000 packets.

If you are using both Magic Transit and Spectrum for IP addresses that overlap, you can use only the Magic Transit node.

​​ Attack nodes

​​ dosdAttackAnalyticsGroups

This node provides information about DDoS attacks detected and mitigated by Cloudflare’s main DDoS protection system, the denial of service daemon (dosd). This node includes attack metadata such as:

  • startDatetime
  • endDatetime
  • attackType
  • sourceIp

Each row represents an attack event. Each attack has a unique ID.

The sample rate is dynamic and based on the volume of packets, ranging from 1/100 to 1/10,000 packets.

​​ dosdNetworkAnalyticsAdaptiveGroups

This node complements the information in the dosdAttackAnalyticsGroups node. Provides deep packet-level information about DDoS attack packets mitigated by dosd, including fields such as:

  • ipProtocol
  • ipv4Checksum
  • ipv4Options
  • tcpSequenceNumber
  • tcpChecksum
  • icmpCode

Each row represents a packet sample. The sample rate is 1/10,000 packets.

​​ flowtrackdNetworkAnalyticsAdaptiveGroups

This node is only available to Magic Transit customers. Provides metadata about out-of-state TCP DDoS attacks mitigated by flowtrackd, Cloudflare’s Advanced TCP Protection system.

flowtrackd does not use the following ID fields: attack ID, rule ID, and ruleset ID.

The sample rate is 1/10,000 packets.

​​ magicFirewallNetworkAnalyticsAdaptiveGroups

This node is only available to Magic Transit customers. Provides information about packets that were matched against customer-configured Magic Firewall rules.

Each row represents a packet sample that matches a Magic Firewall rule.

Magic Firewall does not use attack IDs, only rule IDs and ruleset IDs.

The sample rate is dynamic and based on the volume of packets, ranging from 1/100 to 1/1,000,000 packets.
