MetricReporter
If the reporter was instantiated generically and hence parameter-less, this method is the place where the reporter sets it's basic fields based on configuration values. Otherwise, this method will typically be a no-op since resources can be acquired in the constructor.
This method is always called first on a newly instantiated reporter.
