Turning many standard dimensions into non-segmentable attributes

[vgorbenko]

After analyzing usage of standard dimensions in AppInsights, we decided to turn many of non-commonly used dimensions into plain properties. This will make it easier to find the ones that are important (instead of scrolling through long lists), will increase performance of AppInsights UI, and, of course, will reduce our cost of storing data that only very few people need. Below you can find a list of dimensions that will stay, will be removed, and some FAQs about the planned change.

Here is the current consolidated list of dimensions that are staying:

1. availability.result
2. availability.runLocation
3. availability.testName
4. basicException.problemId
5. billingMetric.documentType
6. clientPerformance.performanceBucket
7. context.data.isSynthetic
8. context.device.browserVersion
9. context.device.deviceModel
10. context.device.osVersion
11. context.device.roleInstance
12. context.device.type
13. context.location.country
14. context.operation.name
15. event.name
16. remoteDependency.baseName
17. remoteDependency.durationMetric.name
18. remoteDependency.performanceBucket
19. remoteDependency.resultCode
20. remoteDependency.success
21. request.performanceBucket
22. request.responseCode
23. request.success
24. view.name
25. view.performanceBucket
26. context.device.deviceName
27. context.device.screenResolution.value
28. view.name
29. context.application.version
30. Context.sessionid
31. Context.anonuserid
32. Insight.severity
33. Insight.provider

# These are the FAQs about the change:

Q: Will SDK continue to collect the values for the dimensions that are being cut? A: There are no plan on changing AI SDK side. All data will remain available at: • Event details screen • Continuous export

_Q: If all data continues to float to AI, what areas are really impacted by the cut? _ A: The users will not be able to use the affected dimensions in the Metrics Explorer “group-by” drop-down box. Also, these dimensions will no longer be available in the filter list (in ME and Diagnostic Search).

_Q: Will I continue to be able to group-by/ filter by custom dimensions? _ A: Yes, absolutely. Custom dimensions will continue to work the way they work today.
