The above shows an example output for Metrics exporter. It looks to be repeating Resource info and InstrumentationScope(Meter) information for each and every data point.

This can be improved!

1. Resource can be printed just once, as it is fixed for entire exported items.
2. InstrumentationScope can be printed once per Metric.

This'll make it much easier to follow the output. It maybe worth considering to adopt the same format used by Collector's debug output - that one is very human readable.

What is the expected behavior?

Description has the details.

Which alternative solutions or features have you considered?

None.
