Interface MetricsProgrammaticConfig

All Known Implementing Classes:
SeMetricsProgrammaticConfig
public interface MetricsProgrammaticConfig
Programmatic (rather than user-configurable) settings that govern certain metrics behavior.

Implementations of this interface are typically provided by Helidon itself rather than developers building applications and are not intended for per-deployment (or even per-application) customization.
