[FEATURE REQ] Unable to override specific field in Application Insights schema

[TimothyMothra]

I'm opening this issue to track and consolidate all other reported instances of this problem.
Currently, the Azure Monitor Exporter does not offer any mechanism to override every attribute in the Application Insights schema. While several attributes are mapped today, several others are not. My team is investigating how to better document this and how to close this feature gap.

This affects users manually creating telemetry and users wishing to override attributes created by an Instrumentation library.

Affected Libraries

• Azure.Monitor.OpenTelemetry.Exporter
• Azure.Monitor.OpenTelemetry.AspNetCore

Reported Issues

• [FEATURE REQ] Support for extending app insights Dependency.Type values #45112
  Override Dependency.Type because unsupported dependencies show as "OTHER" and displays in UX. (E2E transactions)
