Dashboard / OTel : Provide summary/stats of how much data is being emitted

APMs commonly charge based on the amount of data that is collected from the application. Developers typically don't have any idea of how much data they are creating until they get a bill.

Tweaking sampling rates and log message filtering can have a big affect on the amount of data that is produced.

As part of a developer-focused dashboard, we could provide a view of how data is being emitted when the application is being run in the dashboard.
I am thinking something like:

Logging:
Messages / 1000 requests: 4500
Size / 1000 requests: 1.2MB

Tracing:
Spans / 1000 requests: 3400
Size / 1000 requests: 1.2MB

Metrics:
Size: 12KB/s
