> Updated description based on feedback:
> We have a need to publish metrics out of some short-living processes, which is not really
well-suited to the current metrics system implementation which periodically publishes metrics
asynchronously (a behavior that works great for long-living processes). Of course I could
write my own metrics system, but it seems like such a waste to rewrite all the awesome code
currently in the MetricsSystemImpl and supporting classes.
> The way this JIRA solves this problem is adding a new method publishMetricsNow() to the
MetricsSystemImpl() class, that does a synchronous out-of-band push of the metrics from the
sources to the sink. I also add a method to MetricsSinkAdapter (putMetricsImmediate) to support
that change.
