Detailed Description

Send a metric to Graphite.

Graphite accepts metrics in a tree hiereachy, using '.' as a delimiter. Therefore, the metric artdaq.BoardReader.Fragment_Rate will appear in Graphite as: artdaq/ BoardReader/ Fragment_Rate

This plugin sends TCP messages with the following content: [name] [value] [timestamp], units are discarded

GraphiteMetric Constructor.

Parameters
configParameterSet used to configure GraphiteMetric
app_nameName of the application sending metrics
* GraphiteMetric accepts the following Parameters:
