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