Annotation Interface StatisticsGroup

@Retention(RUNTIME) @Target(TYPE) public @interface StatisticsGroup
Marks a group of public statistics of an application, a class implementing Statistics: SmartGears finds every such class of the application, computes each group on its own schedule, once or in each Context (perContext()), and serves the last results without a token at /smartgears/<application>/statistics.

    • order

      int order
      Where the group comes among the groups of the application: the groups are given by their order, then by their identifier.
      Returns:
      the order, 0 unless the group says otherwise
      Default:
      0

    • perContext

      boolean perContext
      Whether the group is computed in each Context of the node, each time with the secret of that Context, and published as the total; otherwise it is computed once, with the secret of the container in the Context it publishes from. In a group computed per Context, the figures of the same id are summed: numbers, and the numbers by name of distributions, states and values; of instants the latest is kept. Averages, medians and maxima do not belong to such a group.
      Returns:
      true for a group computed per Context, false unless the group says otherwise
      Default:
      false
