如何使用Java SDK查询最近五分钟的Azure存储指标

Question

I have written a stand alone code to get the metrics for Azure Storage Blob Services but i want to get only last 5mins metric how can i get it from $MetricsMinutePrimaryTransactionsBlob please suggest

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());

Answer 1

There is no simple way to query last 5 minutes rows now. As PartitionKey is the time stamp in minute unit, you can propose the query filter for last 20 minutes rows and find last 5 minutes rows from the result locally.

TableQuery.combineFilters(
    TableQuery.generateFilterCondition("PartitionKey", QueryComparisons.GreaterThanOrEqual, "20170602T1400"),
    TableOperators.And,
    TableQuery.generateFilterCondition("PartitionKey", QueryComparisons.LessThanOrEqual, "20170602T1420"));

According to your description and @FrancisYu-MSFT reply, I wrote a sample code and reproduced your current issue.

Here is my sample code.

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());
}

Then I got the same issue when running my code, which was caused by the metrics table $MetricsMinutePrimaryTransactionsBlob not exists, so you need to enable the related Diagnostics options to create it, as the figure below.
