[英]Why app insight generate _MS.links column for event hub dependency telemetry?
I added event hub to my application and App Insight started to emit telemetry with for event dependency.我在我的应用程序中添加了事件中心,App Insight 开始针对事件依赖发出遥测数据。 One of the column in this dependency is _MS.links causing downstream workflows to fail due to column name.
此依赖项中的一列是 _MS.links,导致下游工作流因列名而失败。
Why app insight emits column with _MS.为什么应用洞察力会发出带有 _MS 的列。 prefix?
字首?
具有特殊字符的名称应引用为x["y"]
或x['y']
(而不是xy
),在这种情况下: customDimensions["_MS.links"]
,如此处所示
customDimensions["_MS.links"]
is the "Operation links" used alongside Operation Id ( operation_Id
), Parent Id ( operation_ParentId
) and Id ( id
) for Application Insights to correlate telemetry. customDimensions["_MS.links"]
是与操作 ID ( operation_Id
)、父 ID ( operation_ParentId
) 和 ID ( id
) 一起使用的“操作链接”,用于 Application Insights 关联遥测。 See Understanding operation IDs & operation links when working with Event Hubs for more info on that.有关详细信息,请参阅使用事件中心时了解操作 ID 和操作链接。
