如何在Azure Application Insights Analytics上做到与众不同

Question

我目前使用Application Insights Analytics运行以下查询：

customEvents 
| where name == 'Event Name 1' 
| project ['Column One'] = customDimensions['CD1'], ['Column Two'] = customDimensions['CD2'], ['Column Three'] = customDimensions['CD3']

上面的查询返回了一些如下结果：

Column One | Column Two | Column Three
    A      |     2      |      D
    B      |     3      |      E
    C      |     2      |      F

如何获取查询以仅返回第二列上的不同值？基本上我希望我的结果是：

Column One | Column Two | Column Three
    A      |     2      |      D
    B      |     3      |      E

任何帮助将不胜感激！

Answer 1

您可以执行以下操作：

customEvents 
| where name == 'Event Name 1' 
| project ['Column One'] = tostring(customDimensions['CD1']),
          ['Column Two'] = tostring(customDimensions['CD2']),
          ['Column Three'] = tostring(customDimensions['CD3'])
| summarize any(['Column One']), any(['Column Three']) by ['Column Two']

这将获取第一个-不一定是“ A，C”对中的A。如果要排除“ C”，则需要使用其他汇总聚合器，例如makelist / makeset。
