Querying Workers Metrics with GraphQL

In this example, we are going to use the GraphQL Analytics API to query for Workers Metrics over a specified time period. We can query up to one month of data for dates up to three months ago.

The following API call will request a Worker script’s metrics over a one day period, and output the requested fields. Be sure to replace <CLOUDFLARE_ACCOUNT_ID>, <EMAIL>, and <API_KEY> with your API credentials, and adjust the datetimeStart, datetimeEnd, and scriptName variables as needed.

echo '{ "query":  "query GetWorkersAnalytics($accountTag: string, $datetimeStart: string, $datetimeEnd: string, $scriptName: string) {    viewer {      accounts(filter: {accountTag: $accountTag}) {        workersInvocationsAdaptive(limit: 100, filter: {          scriptName: $scriptName,          datetime_geq: $datetimeStart,          datetime_leq: $datetimeEnd        }) {          sum {            subrequests            requests            errors          }          quantiles {            cpuTimeP50            cpuTimeP99          }          dimensions{            datetime            scriptName            status          }        }      }    }  }",  "variables": {    "accountTag": "<CLOUDFLARE_ACCOUNT_ID>",    "datetimeStart": "2022-08-04T00:00:00.000Z",    "datetimeEnd": "2022-08-04T01:00:00.000Z",    "scriptName": "worker-subrequest-test-client"  }}' | tr -d '\n' | curl \  --header "X-Auth-Email: <EMAIL>" \  --header "X-Auth-Key: <API_KEY>" \  --header "Content-Type: application/json" \  --silent \  --data @- \  https://api.cloudflare.com/client/v4/graphql/

The results returned will be in JSON (as requested), so piping the output to jq will make them easier to read, like in the following example:

... | curl \  --header "X-Auth-Email: <EMAIL>" \  --header "X-Auth-Key: <API_KEY>" \  --header "Content-Type: application/json" \  --silent \  --data @- \  https://api.cloudflare.com/client/v4/graphql/ | jq .
