資源:LmkRateMetricSet
代表一組 LMK (記憶體不足終止) 指標的單例資源。
這組指標包含 LMK 資料和使用資料,可產生與使用者人數無關的正規化指標。
支援的匯總期間:
DAILY
:指標會以日曆日期間隔匯總。由於歷史限制,目前僅支援 America/Los_Angeles
時區。
支援的指標:
userPerceivedLmkRate
(google.type.Decimal
):在彙整期間,主動使用應用程式時至少感知到一次 LMK 的不重複使用者百分比。如果應用程式顯示任何活動或執行任何前景服務,系統會將應用程式視為處於主動使用狀態。
userPerceivedLmkRate7dUserWeighted
(google.type.Decimal
):過去 7 天的userPerceivedLmkRate
累計平均值。每日值會根據當天不重複使用者人數加權計算。
userPerceivedLmkRate28dUserWeighted
(google.type.Decimal
):過去 28 天的userPerceivedLmkRate
累計平均值。每日值會根據當天不重複使用者人數加權計算。
distinctUsers
(google.type.Decimal
):匯總期間內的不重複使用者人數,用來做為 userPerceivedLmkRate
指標的正規化值。如果使用者在彙整期間於前景使用應用程式,系統就會將他們計入這個指標。請務必不要進一步匯總這項計數,否則可能會導致系統重複計算使用者。系統會根據值的大小,將值四捨五入至最接近的 10、100、1,000 或 1,000,000 倍數。
支援的尺寸:
apiLevel
(string
):使用者裝置上執行的 Android API 級別,例如 26.

Due to historical constraints, the only supported timezone is `America/Los_Angeles`.\n\n**Supported metrics:**\n\n- `userPerceivedLmkRate` (`google.type.Decimal`): Percentage of distinct users in the aggregation period that experienced at least one LMK while they were actively using your app (a user-perceived LMK). An app is considered to be in active use if it is displaying any activity or executing any foreground service.\n- `userPerceivedLmkRate7dUserWeighted` (`google.type.Decimal`): Rolling average value of `userPerceivedLmkRate` in the last 7 days. The daily values are weighted by the count of distinct users for the day.\n- `userPerceivedLmkRate28dUserWeighted` (`google.type.Decimal`): Rolling average value of `userPerceivedLmkRate` in the last 28 days. The daily values are weighted by the count of distinct users for the day.\n- `distinctUsers` (`google.type.Decimal`): Count of distinct users in the aggregation period that were used as normalization value for the `userPerceivedLmkRate` metrics. A user is counted in this metric if they used the app in the foreground during the aggregation period. Care must be taken not to aggregate this count further, as it may result in users being counted multiple times. The value is rounded to the nearest multiple of 10, 100, 1,000 or 1,000,000, depending on the magnitude of the value.\n\n**Supported dimensions:**\n\n- `apiLevel` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): the API level of Android that was running on the user's device, e.g., 26.\n- `versionCode` ([int64](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.int64_value)): version of the app that was running on the user's device.\n- `deviceModel` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): unique identifier of the user's device model. The form of the identifier is 'deviceBrand/device', where deviceBrand corresponds to Build.BRAND and device corresponds to Build.DEVICE, e.g., google/coral.\n- `deviceBrand` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): unique identifier of the user's device brand, e.g., google.\n- `deviceType` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): the type (also known as form factor) of the user's device, e.g., PHONE.\n- `countryCode` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): the country or region of the user's device based on their IP address, represented as a 2-letter ISO-3166 code (e.g. US for the United States).\n- `deviceRamBucket` ([int64](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.int64_value)): RAM of the device, in MB, in buckets (3GB, 4GB, etc.).\n- `deviceSocMake` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): Make of the device's primary system-on-chip, e.g., Samsung. [Reference](https://developer.android.com/reference/android/os/Build#SOC_MANUFACTURER)\n- `deviceSocModel` ([string](/play/developer/reporting/reference/rest/v1beta1/anomalies#DimensionValue.FIELDS.string_value)): Model of the device's primary system-on-chip, e.g., \"Exynos 2100\".
