Querying HTTP events by hostname with GraphQL
In this example, we are going to use the GraphQL Analytics API to query aggregated metrics about HTTP events by hostname over a specific period of time.
The following API call will request the number of visits and edge response bytes for the custom hostname hostname.example.com over a four day period. Be sure to replace CLOUDFLARE_ZONE_ID AND CLOUDFLARE_API_TOKEN with your zone ID and API credentials, and adjust the datetime_geq and datetime_leq values as needed.
API Call
echo '{ "query": "query RequestsAndDataTransferByHostname($zoneTag: string, $filter:filter) { viewer { zones(filter: {zoneTag: $zoneTag}) { httpRequestsAdaptiveGroups(limit: 10, filter: $filter) { sum { visits edgeResponseBytes } dimensions { datetimeHour } } } } }", "variables": { "zoneTag": "CLOUDFLARE_ZONE_ID", "filter": { "datetime_geq": "2022-07-20T11:00:00Z", "datetime_lt": "2022-07-24T12:00:00Z", "clientRequestHTTPHost": "hostname.example.com", "requestSource": "eyeball" } }}' | tr -d '\n' | curl \ --header "Authorization: Bearer <API_TOKEN>" \ --header "Accept: application/json" \ --silent \ --data @- \ https://api.cloudflare.com/client/v4/graphql | jq .
The returned results will be in JSON format (as requested), so piping the output to jq will make them easier to read, like in the following example:
{ "data": { "viewer": { "zones": [ { "httpRequestsAdaptiveGroups": [ { "dimensions": { "datetimeHour": "2022-07-21T10:00:00Z" }, "sum": { "edgeResponseBytes": 19849385, "visits": 4383 } }, { "dimensions": { "datetimeHour": "2022-07-21T06:00:00Z" }, "sum": { "edgeResponseBytes": 20607204, "visits": 4375 } }, { "dimensions": { "datetimeHour": "2022-07-26T05:00:00Z" }, "sum": { "edgeResponseBytes": 20170839, "visits": 4519 } }, { "dimensions": { "datetimeHour": "2022-07-23T08:00:00Z" }, "sum": { "edgeResponseBytes": 20141860, "visits": 4448 } }, { "dimensions": { "datetimeHour": "2022-07-25T15:00:00Z" }, "sum": { "edgeResponseBytes": 21070367, "visits": 4469 } }, { "dimensions": { "datetimeHour": "2022-07-28T08:00:00Z" }, "sum": { "edgeResponseBytes": 19200774, "visits": 4345 } }, { "dimensions": { "datetimeHour": "2022-07-26T02:00:00Z" }, "sum": { "edgeResponseBytes": 20758067, "visits": 4502 } }, { "dimensions": { "datetimeHour": "2022-07-20T19:00:00Z" }, "sum": { "edgeResponseBytes": 22127811, "visits": 4443 } }, { "dimensions": { "datetimeHour": "2022-07-27T15:00:00Z" }, "sum": { "edgeResponseBytes": 20480644, "visits": 4268 } }, { "dimensions": { "datetimeHour": "2022-07-27T17:00:00Z" }, "sum": { "edgeResponseBytes": 19885704, "visits": 4287 } } ] } ] } }, "errors": null
