支持的聚合Supported aggregations

每个表中的“聚合类型”列对应于为图表或警报选择指标时使用的默认聚合。The Aggregation Type column in each table corresponds to the default aggregation that is used when the metric is selected for a chart or alert.

对于大多数指标，所有聚合类型都是有效的；但是，对于计数指标，即“计价单位”列值为“计数”的指标，只有一些聚合是有效的 。For most metrics, all aggregation types are valid; however, for count metrics, those with a Unit column value of Count, only some aggregations are valid. 计数指标可以是以下两种类型之一：Count metrics can be one of two types:

• 对于单点计数指标，IoT 中心每次执行测量操作时都会注册一个数据点（实质上为 1）。For Single-point count metrics, IoT Hub registers a single data point -- essentially a 1 -- every time the measured operation occurs. 然后 Azure Monitor 在指定的粒度上对这些数据点进行求和。Azure Monitor then sums these data points over the specified granularity. 单点指标的示例有发送的遥测消息数和已完成的 C2D 消息传递次数 。Examples of Single-point metrics are Telemetry messages sent and C2D message deliveries completed. 对于这些指标，唯一相关的聚合类型为总计（总和）。For these metrics, the only relevant aggregation type is Total (Sum). 通过门户可选择最小值、最大值和平均值；然而，这些值始终为 1。The portal allows you to choose minimum, maximum, and average; however, these values will always be 1.

• 对于快照计数指标，当进行测量操作时，IoT 中心将登记总计数。For Snapshot count metrics, IoT Hub registers a total count when the measured operation occurs. 当前，IoT 中心发布了三种快照指标：已使用的消息总数、设备总数（预览）和已连接设备数（预览） 。Currently, there are three Snapshot metrics emitted by IoT Hub: Total number of messages used, Total devices (preview), and Connected devices (preview). 因为这些指标在每次发出时都显示一个“总数”，所以在指定的粒度上对它们进行求和没有任何意义。Because these metrics present a "total" quantity every time they are emitted, summing them over the specified granularity makes no sense. Azure Monitor 仅限为这些指标的聚合类型选择平均值、最小值和最大值。Azure Monitor limits you to selecting average, minimum, and maximum for the aggregation type for these metrics.

• IoT 中心将某个终结点标记为死终结点，或者IoT Hub marks an endpoint as dead, or
• 从终结点收到的任何错误。Any errors received from an endpoint.

此类别不包含有关消息本身的特定错误（例如设备限制错误），这些错误在“设备遥测”类别下报告。This category does not include specific errors about the messages themselves (like device throttling errors), which are reported under the "device telemetry" category.

{
    "records":
    [
        {
            "time":"2019-12-12T03:25:14Z",
