通过 az rest --method get  如何获得Event Hub Entity 级的统计指标？

问题解答

查阅文档  https://learn.microsoft.com/en-us/rest/api/monitor/metrics/list?tabs=HTTP ,  可以通过 **filter 参数指定 EntityName eq '*' ** 或者 EntityName eq '<entity-name>'。

Windows系统的CMD中，使用AZ CLI测试：

# EntityName eq '*'
az rest --debug --method get --url "/subscriptions/<your subscription id>/resourceGroups/<your resource group>
/providers/Microsoft.EventHub/namespaces/<event-hub-name>/providers/microsoft.Insights/metrics?
timespan=2022-08-31T07:03:32.960Z/2022-08-31T07:57:34.794Z
&interval=PT5M&metricnames=IncomingRequests&aggregation=total
&metricNamespace=microsoft.eventhub%2Fnamespaces&top=10
&orderby=total desc&
$filter=EntityName eq '*'
&api-version=2019-07-01"

# EntityName eq 'entity-name'
az rest --method get --url "/subscriptions/<your subscription id>/resourceGroups/<your resource group>
/providers/Microsoft.EventHub/namespaces/<event-hub-name>/providers/microsoft.Insights/metrics?
timespan=2022-08-31T07:03:32.960Z/2022-08-31T07:57:34.794Z
&interval=PT5M&metricnames=IncomingRequests&aggregation=total
&metricNamespace=microsoft.eventhub%2Fnamespaces&top=10
&orderby=total desc
&$filter=EntityName eq 'kafka-test'
&api-version=2019-07-01"

Linux系统中，需要对url参数中的$filter进行转义，变为 $filter 。 

az rest --debug --method get --url "/subscriptions/<your subscription id>/resourceGroups/<your resource group>
/providers/Microsoft.EventHub/namespaces/<event-hub-name>/providers/microsoft.Insights/metrics?
timespan=2022-08-31T07:03:32.960Z/2022-08-31T07:57:34.794Z
&interval=PT1M
&metricnames=SuccessfulRequests
&aggregation=total
&metricNamespace=microsoft.eventhub%2Fnamespaces
&top=10
&orderby=total asc
&\$filter=EntityName eq 'kafka-test'
&api-version=2019-07-01"
