azure - 应用洞察 : How to query full trace of azure function executions containing errors?

Question

我想使用 Application Insights 分析 Azure Functions 的日志输出。如果函数执行的日志输出至少包含一个错误，我想查看该执行的整个日志输出。

起点:

traces 
| where severityLevel == 3
| where operation_Name == "MyFunctionName" 
| project timestamp, operation_Name, message

但这仅提供错误本身，而不提供函数执行的其他输出。

Answer 1

对于 Azure Functions V1:

traces 
| where severityLevel == 3
| where operation_Id != ""
| where operation_Name == "MyFunctionName" 
| project operation_Name , operation_Id, severityLevel    
| join (traces | project timestamp, operation_Id,  message ) on operation_Id 
| project timestamp, operation_Name, operation_Id, message

具有相同操作_Id 的所有行都属于一个函数执行。

对于 Azure Functions V2:

traces 
| extend invocationId = tostring(customDimensions.InvocationId)
| where severityLevel == 3
| where invocationId != ""
| where operation_Name == "MyFunctionName" 
| project operation_Name, severityLevel, invocationId    
| join (traces |extend invocationId = tostring(customDimensions.InvocationId)| project timestamp, invocationId,  message ) on invocationId  
| project timestamp, operation_Name, message, invocationId

具有相同 invokingId 的所有行都属于一个函数执行。
