Network Analytics v1 to Network Analytics v2

In early 2020, Cloudflare released the first version of the Network Analytics dashboard and its corresponding API. The second version (Network Analytics v2) was made available on 2021-09-13.

Warning

Network Analytics v1 (NAv1) is now deprecated. For more information on Network Analytics v2 (NAv2), refer to Cloudflare Network Analytics.

Feature comparison

The following table compares the features of NAv1 and NAv2:

Feature	NAv1	NAv2
Sampling rate	1/8,192 packets	Varies between 1/100 and 1/1,000,000 packets, depending on the mitigation service.
Sampling method	Core Sample Enrichment	Edge Sample Enrichment
Historical data retention method	Aggregated roll-ups	Adaptive Bit Rate
Retention period	1-min roll-ups: 30 days 1-hour roll-ups: 6 months 1-day roll-ups: 1 year Attack roll-ups: 1 year	All nodes: 16 weeks
Attack mitigation systems	dosd	dosd, flowtrackd*, and Magic Firewall*
Examples of new fields	n/a	Rule ID GRE tunnel ID Packet size

* Applicable only for Magic Transit customers.

For more information on the differences in terms of sampling method and historical data retention, refer to Main differences between Network Analytics v1 and v2.

Note

The attackId field value may be different between NAv1 and NAv2 for the same attack.

Node comparison

NAv2 uses the same API endpoint but makes use of new nodes. While NAv1 has three nodes for aggregated roll-ups for all traffic and attacks, and one node for attacks, NAv2 has one node for all traffic and attacks, and four separate nodes for attacks that vary based on the mitigation system.

Node type	NAv1	NAv2 for Magic Transit	NAv2 for Spectrum
Main node(s)	ipFlows1mGroups ipFlows1hGroups ipFlows1dGroups	magicTransitNetworkAnalyticsAdaptiveGroups	spectrumNetworkAnalyticsAdaptiveGroups
Attack node(s)	ipFlows1mAttacksGroups	dosdNetworkAnalyticsAdaptiveGroups dosdAttackAnalyticsGroups flowtrackdNetworkAnalyticsAdaptiveGroups magicFirewallNetworkAnalyticsAdaptiveGroups	dosdNetworkAnalyticsAdaptiveGroups dosdAttackAnalyticsGroups

Each row represents one packet sample. The data is sampled at Cloudflare’s edge at various rates. You can also query the sample rate from the nodes using the sample_interval field.

For reference information on NAv2 nodes, refer to the NAv2 node reference.

Obtaining data for ingress traffic only

All the NAv2 *AnalyticsAdaptiveGroups nodes include data for ingress and egress traffic. To obtain data about ingress traffic only, include direction: "ingress" in your GraphQL query filter.

Schema comparison

Refer to NAv1 to NAv2 schema map for a mapping of schema fields from NAv1 nodes to NAv2 nodes. Follow this recommended mapping when migrating to NAv2.

Example

The following example queries the top 20 logs of traffic dropped by mitigation systems different from Magic Firewall within a given time range, ordered by destination IP address.

{
  viewer
  {
    accounts(filter: {accountTag: "<REDACTED>"})
    {
      magicTransitNetworkAnalyticsAdaptiveGroups(
        filter: {
          datetime_gt: "2021-10-01T00:00:00Z",
          datetime_lt: "2021-10-05T00:00:00Z",
          outcome_like: "drop",
          mitigationSystem_neq: "magic-firewall"
        },
        limit: 20,
        orderBy: [ipDestinationAddress_ASC])
      {
        dimensions {
          outcome
          mitigationSystem
          ipSourceAddress
          ipDestinationAddress
          ipProtocol
          destinationPort
        }
      }
    }
  }
}

Final remarks

The mitigationSystem field can take one the following values:

• dosd for DDoS managed rulesets (Network-layer DDoS Attack Protection or HTTP DDoS Attack Protection).
• flowtrackd for Advanced TCP Protection.
• magic-firewall for Magic Firewall.
• Empty string for unmitigated traffic.
