Component(s)

exporter/azuremonitor

What happened?

Description

When mapping Logs to App Insights traces, it is not mapping Attributes to CustomDementions like it does for spans. This loses data when using formatted logging.

Steps to Reproduce

Log data using formatted logs.

logger.LogInformation("Info {data}", 123);

Expected Result

Attributes (log args) display as CustomDimensions.

Actual Result

CustomDimensions is empty.

Is there any progress on this? It seems that it's also missing additional properties like cloud_RoleName. At the custom dimensions we are also expecting the service.name.
