> Currently alert engine open metric system per tuple which will waste connection and throughput:
> https://github.com/apache/incubator-eagle/blob/master/eagle-core/eagle-alert-parent/eagle-alert/alert-engine/src/main/java/org/apache/eagle/alert/engine/runner/AlertBolt.java#L131
> In order to export metric in eagle, app developer (including alert engine) should never touch MetricSystem directly but  should use storm native metric framework to declare and update metric, and eagle framework will automatically receive metrics and export as configured.
