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.

​​ API Call

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 .
