Class StatsRegistry

  • All Implemented Interfaces:
    
public final class StatsRegistry<T extends Meter>

    Facilitates standard Micrometer Meter usage when we need to use them with parameters. For example, there might be common 'processingTime' timer and we want to use it for action=action1, action=action2, etc.

    Also it has a feature that context data for the target tag names is automatically retrieved from ExecutionContextManager and attached to data points generated by this registry's meters.

    Note: we introduce multiple overloaded getMeter methods here (getMeter(tag), getMeter(tag1, tag2), etc) instead of providing generic varargs-based processing because stats collection is expected to be performed quite often. Hence, we want to avoid new array construction every time getMeter is called.
