# 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_TAG>` and `<API_TOKEN>`[1](#user-content-fn-1) with your API credentials, and adjust the `datetimeStart`, `datetimeEnd`, and `scriptName` variables as needed.

## API Call

Terminal window

```

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_TAG>",

    "datetimeStart": "2022-08-04T00:00:00.000Z",

    "datetimeEnd": "2022-08-04T01:00:00.000Z",

    "scriptName": "worker-subrequest-test-client"

  }

}' | 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 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:

Terminal window

```

... | 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 .
