Types ¶
type BucketDataMetric ¶
type BucketDataMetric struct {
Rate float64 `json:"rate,omitempty"`
Milestone string `json:"milestone,omitempty"`
LowVolume bool `json:"low_volume,omitempty"`
}
BucketDataMetric contains metric details for a specific bucket in the UMA Export Server response. These fields correspond to those used in ChromeStatus: https://github.com/GoogleChrome/chromium-dashboard/blob/35ccb75ce0ba9a599f9adb71ed93224621a4177a/internals/fetchmetrics.py#L148-L150 You can also refer to the google3 code for the structure of the body too.
type BucketDataMetrics ¶
type BucketDataMetrics map[int64]BucketDataMetric
BucketDataMetrics maps the bucket IDs (from histograms in https://chromium.googlesource.com/chromium/src/+/main/tools/metrics/histograms/enums.xml) to their corresponding metrics. This map is returned as a field in the UMA Export Server response.
Keys: Integer values representing bucket IDs within a histogram. This integer is the "value" for each enum value in enums.xml. Values: Metric details (see BucketDataMetric).
Refer to the corresponding mojom file for a specific histogram to see the definitions of these integer values. Below is a mapping between histogram and mojom file: - WebDXFeatureObserver: https://chromium.googlesource.com/chromium/chromium/src/+/main:third_party/blink/public/mojom/use_counter/metrics/webdx_feature.mojom
type HistogramEnumValue ¶
HistogramEnumValue contains the information for a single enumeration inside a given histogram.
type HistogramMapping ¶
type HistogramMapping map[HistogramName][]HistogramEnumValue
Each histogram in the enums file contains a list of enum values.
type HistogramName ¶
type HistogramName string
Data from https://chromium.googlesource.com/chromium/src/+/main/tools/metrics/histograms/enums.xml
const ( // Generated from third_party/blink/public/mojom/use_counter/metrics/webdx_feature.mojom. WebDXFeatureEnum HistogramName = "WebDXFeatureObserver" )
Names come from the enums file above.
type UMAExportQuery ¶
type UMAExportQuery string
UMAExportQuery represents the enumeration of queries that can be sent to the UMA Export Server.
const (
WebDXFeaturesQuery UMAExportQuery = "usecounter.webdxfeatures"
)
