## org.red5.server.api.statistics
Interface IStatisticsService

All Known Implementing Classes:
  StatisticsService

    public interface IStatisticsService

Statistics methods for Red5. They can be used to poll for updates of given elements inside the server. Statistics data will be stored as properties of different shared objects. Use `getScopeStatisticsSO` and `getSharedObjectStatisticsSO` to get these shared objects. The property names are `scopeName` for scope attributes and `scopeName|sharedObjectName` for shared object attributes. Each property holds a Map containing key/value mappings of the corresponding attributes. Sometime in the future, the updates on the shared objects will be done automatically so a client doesn't need to poll for them.
