Is your feature request related to a problem? Please describe.

The interval processor's main goal is to decrease the collector's data point throughput. Gauges and summaries still weren't implemented.

Describe the solution you'd like

Instead of passing through all gauges and summaries, we should pass only the last one.

Describe alternatives you've considered
