如何查询存储在 azure WADMETRICS 表中的指标？
[英]How to query metrics stored in azure WADMETRICS table?
问题描述
Using Extended metrics I am trying to retrieve certain metrics for certain VMS.
使用扩展指标我试图检索某些 VMS 的某些指标。 Every query seems to take extremely long, as new records are made for each VM every 15 seconds in the table.每个查询似乎都需要很长时间，因为表中每 15 秒就会为每个 VM 创建新记录。
So I'm trying to query the table in the last 5 minutes, but it's not working and giving me an error.所以我试图在最后 5 分钟内查询该表，但它不起作用并给我一个错误。 Does anyone know how to query these WADMETRICS tables?有谁知道如何查询这些 WADMETRICS 表？
My code.我的代码。
CloudStorageAccount account = CloudStorageAccount.parse(connectionString);
CloudTableClient cloudTableClient = account.createCloudTableClient();
DateTime fiveMinutesAgo = DateTime.now().minusMinutes(5);
String queryString = TableQuery.generateFilterCondition("Timestamp", TableQuery.QueryComparisons.GREATER_THAN_OR_EQUAL, fiveMinutesAgo.toString());
TableQuery<TableServiceEntity> query = TableQuery.from(TableServiceEntity.class).where(queryString);
CloudTable table = cloudTableClient.getTableReference("WADMetricsPT1MP10DV2S20191017");
System.out.println(table.exists());
System.out.println(table.getName());
for (TableServiceEntity entity : table.execute(query)) {
System.out.println(entity.getPartitionKey() + "\t" + entity.getRowKey());
}
What I get back when I run this.当我运行这个时我得到了什么。
An error occurred while enumerating the result, check the original exception for details.

According to my test, if you want to query the WADMETRICS tables by filtering timetap, please refer to the following code:根据我的测试，如果想通过过滤timetap来查询WADMETRICS表，请参考以下代码：
CloudStorageAccount account = CloudStorageAccount.parse("connection string");
CloudTableClient client = account.createCloudTableClient();
CloudTable table = client.getTableReference("WADMetricsPT1MP10DV2S20191017");
System.out.println(table.exists());
System.out.println(table.getName());
Calendar cal = new GregorianCalendar(TimeZone.getTimeZone("UTC"));
cal.add(Calendar.HOUR, -19);
cal.add(Calendar.MINUTE,-21);
Date date = cal.getTime();
// SimpleDateFormat df = new SimpleDateFormat ("yyyy-MM-dd'T'HH:mm:ss.SSSSSSS'Z'");
// date = df.parse(df.format(date));
//
System.out.println(date.toString());
String queryString = TableQuery.generateFilterCondition("Timestamp",TableQuery.QueryComparisons.GREATER_THAN_OR_EQUAL, date);
TableQuery<TableServiceEntity> query = TableQuery.from(TableServiceEntity.class).where(queryString);
Iterable<TableServiceEntity> results = table.execute(query);
int i=0;
for (TableServiceEntity entity:results
) {
i +=1;
System.out.println(entity.getPartitionKey());
}
System.out.println(i);
Besides, you also can query you Azure table on the portal:此外，您还可以在门户中查询您的 Azure 表：
