java - 如何使用 Java SDK 查询最近五分钟的 Azure 存储指标

Question

我编写了一个独立代码来获取 Azure 存储 Blob 服务的指标，但我只想获取最后 5 分钟的指标，如何从 $MetricsMinutePrimaryTransactionsBlob 获取它，请提出建议

CloudTable cloudMetric = tableClient.getTableReference(cloud
                .getHourMetricsTable(StorageService.BLOB).getName());
        String partitionFilter2 = TableQuery.generateFilterCondition(
                "PartitionKey", QueryComparisons.EQUAL, "20170602T1400");
        String rowFilter3 = TableQuery.generateFilterCondition("RowKey",
                QueryComparisons.EQUAL, "user;All");
        String combinedFilter = TableQuery.combineFilters(partitionFilter2,
                Operators.AND, rowFilter3);
        TableQuery<MetricsPojo> partitionQuery2 = TableQuery.from(
                MetricsPojo.class).where(combinedFilter);
        for (MetricsPojo capacityMetrics2 : cloudMetric
                .execute(partitionQuery2)) {
            System.out.println(capacityMetrics2);
            System.out.println(capacityMetrics2.getPartitionKey() + "\n"
                    + capacityMetrics2.getRowKey() + "\n"
                    + capacityMetrics2.getTimestamp());

根据您的描述和@FrancisYu-MSFT的回复，我编写了示例代码并重现了您当前的问题。

这是我的示例代码。

String connectionString = String.format("DefaultEndpointsProtocol=http;AccountName=%s;AccountKey=%s", ACCOUNT_NAME, ACCOUNT_KEY);
CloudStorageAccount account = CloudStorageAccount.parse(connectionString);
CloudAnalyticsClient client = account.createCloudAnalyticsClient();
CloudTable metrics = client.getMinuteMetricsTable(StorageService.BLOB);
System.out.println(metrics.getName());
String queryString = TableQuery.combineFilters(
                TableQuery.generateFilterCondition("PartitionKey", QueryComparisons.GREATER_THAN_OR_EQUAL, "20170602T1400"),
                Operators.AND,
                TableQuery.generateFilterCondition("PartitionKey", QueryComparisons.LESS_THAN_OR_EQUAL, "20170602T1420"));
TableQuery<TableServiceEntity> query = TableQuery.from(TableServiceEntity.class).where(queryString);
for(TableServiceEntity entity : metrics.execute(query)) {
    System.out.println(entity.getPartitionKey()+"\t"+entity.getRowKey());
}

然后我在运行代码时遇到了同样的问题，这是由于指标表$MetricsMinutePrimaryTransactionsBlob不存在引起的，因此需要启用相关的Diagnostics选项创建它，如下图。
