azure - 如何使用 Azure Kusto 输出多个变量？

Question

我对 Azure Kusto 查询语言相当陌生。我正在尝试输出 2 个变量。这必须是非常简单的事情，我只是不知道如何。我曾尝试使用数据表、make-series、打印等功能，但无济于事。这是我当前的代码：

let allrequests = requests | project itemCount, resultCode, success, timestamp | where timestamp > now(-1h) and timestamp < now(-5m);

let requestcount = allrequests | summarize sum(itemCount);

let errorcount = allrequests | where toint(resultCode) >= 400 and toint(resultCode) <= 499 | summarize sum(itemCount);

requestcount; errorcount

Answer 1

使用union是一种方法，但如果您希望它们在单行上使用print语句（docs）：

let requestcount = requests
 | summarize sum(itemCount);
let errorcount = exceptions
 | summarize count();
print requests = toscalar(requestcount), exceptions = toscalar(errorcount)

Answer 2

我想到了。您可以使用联合运算符连接结果。

let allrequests = requests | project itemCount, resultCode, success, timestamp | where timestamp > now(-1h) and timestamp < now(-5m);

let requestcount = allrequests | summarize sum(itemCount);

let errorcount = allrequests | where toint(resultCode) >= 400 and toint(resultCode) <= 499 | summarize sum(itemCount);

errorcount | union requestcount
