Querying Cloudflare Network Firewall Samples with GraphQL

In this example, we are going to use the GraphQL Analytics API to query for Cloudflare Network Firewall Samples over a specified time period.

The following API call will request Cloudflare Network Firewall Samples over a one hour period, and output the requested fields. Be sure to replace <CLOUDFLARE_ACCOUNT_TAG> and <API_TOKEN>¹ with your zone tag and API credentials, and adjust the datetime_geg and datetime_leq values to your liking.

API Call

echo '{ "query":
  "query MFWActivity {
    viewer {
      accounts(filter: { accountTag: $accountTag }) {
        magicFirewallSamplesAdaptiveGroups(
          filter: $filter
          limit: 10
          orderBy: [datetimeFiveMinute_DESC]
        ) {
          sum {
            bits
            packets
          }
          dimensions {
            datetimeFiveMinute
            ruleId
          }
        }
      }
    }
  }",
  "variables": {
    "accountTag": "<CLOUDFLARE_ACCOUNT_TAG>",
    "filter": {
      "datetime_geq": "2022-07-24T11:00:00Z",
      "datetime_leq": "2022-07-24T11:10:00Z"
    }
  }
}' | tr -d '\n' | curl --silent \
https://api.cloudflare.com/client/v4/graphql \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data @-

The returned values represent the total number of packets and bits received during the five minute interval for a particular rule. The result will be in JSON (as requested), so piping the output to jq will make it easier to read, like in the following example:

... | curl --silent \
https://api.cloudflare.com/client/v4/graphql \
--header "Authorization: Bearer <API_TOKEN>" \
--header "Accept: application/json" \
--header "Content-Type: application/json" \
--data @- | jq .
