Report data before closing reporter

[posto]

Hi,

A short suggestion to call reporter.report(); before calling reporter.close(), to ensure that the latest data is reported and avoid data loss, before application shutdown. (Especially useful when reporting to Graphite, for example).

Regards, posto
