Spectrum analytics bytime queries for multiple metrics/dimensions only returns one dimension/metric #4197
Description
Confirm this is a Go library issue and not an underlying Cloudflare API issue
- This is an issue with the Go library
Describe the bug
As best as I read the API docs dimensions and metrics should be provided as a comma delimited array and when I query this way via curl I get the values I expect
https://developers.cloudflare.com/api/resources/spectrum/subresources/analytics/subresources/events/
curl -H "Authorization: Bearer *******" "https://api.cloudflare.com/client/v4/zones/*******/spectrum/analytics/events/bytime?metrics=count,bytesIngress,bytesEgress&dimensions=appID,event,coloName,ipVersion&since=$(date -u -v-5M +%Y-%m-%dT%H:%M:%SZ)&timeDelta=minute" | jq .
However after doing some debugging trying to figure out why I was only getting one dimension and metric back I finally figured out that this was the call the SDK was making. Each of the dimensions and metrics are being set as their own query param instead of a single comma delimited one

Here's how I'm setting up the params
params := spectrum.AnalyticsEventBytimeGetParams{
ZoneID: cloudflare.F(zoneID),
Since: cloudflare.F(since),
TimeDelta: cloudflare.F(spectrum.AnalyticsEventBytimeGetParamsTimeDeltaMinute),
Metrics: cloudflare.F([]spectrum.AnalyticsEventBytimeGetParamsMetric{
spectrum.AnalyticsEventBytimeGetParamsMetricCount,
spectrum.AnalyticsEventBytimeGetParamsMetricBytesIngress,
spectrum.AnalyticsEventBytimeGetParamsMetricBytesEgress,
}),
Dimensions: cloudflare.F([]spectrum.Dimension{
spectrum.DimensionAppID,
spectrum.DimensionEvent,
spectrum.DimensionColoName,
spectrum.DimensionIPVersion,
}),
}
Using the tests as an example it looks like I'm setting the dimensions correctly
https://github.com/cloudflare/cloudflare-go/blob/v6.0.1/spectrum/analyticseventbytime_test.go#L34
this nasty hack returns the values I expect
params := spectrum.AnalyticsEventBytimeGetParams{
ZoneID: cloudflare.F(zoneID),
Since: cloudflare.F(since),
TimeDelta: cloudflare.F(spectrum.AnalyticsEventBytimeGetParamsTimeDeltaMinute),
Metrics: cloudflare.F([]spectrum.AnalyticsEventBytimeGetParamsMetric{
// Work around bug that puts these as individual params instead of a single param with comma separated values
spectrum.AnalyticsEventBytimeGetParamsMetric(strings.Join([]string{string(spectrum.AnalyticsEventBytimeGetParamsMetricCount), string(spectrum.AnalyticsEventBytimeGetParamsMetricBytesIngress), string(spectrum.AnalyticsEventBytimeGetParamsMetricBytesEgress)}, ",")),
}),
Dimensions: cloudflare.F([]spectrum.Dimension{
// Work around bug that puts these as individual params instead of a single param with comma separated values
spectrum.Dimension(strings.Join([]string{string(spectrum.DimensionAppID), string(spectrum.DimensionEvent), string(spectrum.DimensionColoName), string(spectrum.DimensionIPVersion)}, ",")),
}),
}
To Reproduce
Make a spectrum analytics bytime call attempting to use multiple metrics and/or dimensions.
Observe that values for only one dimension and metric are returned
