druidEventToGraphite

public GraphiteEvent druidEventToGraphite(com.metamx.emitter.service.ServiceMetricEvent serviceMetricEvent)

Description copied from interface: DruidToGraphiteEventConverter

This function acts as a filter. It returns null if the event is not suppose to be emitted to Graphite Also This function will define the mapping between the druid event dimension's values and Graphite metric Path

Specified by:

druidEventToGraphite in interface DruidToGraphiteEventConverter

Parameters:

serviceMetricEvent - druid metric event to convert

Returns:

null if the event is not white listed, otherwise return GraphiteEvent

The metric path of the graphite event is: .[].[]..

The order of the dimension is the order returned by getOrderedDimValues() Note that this path will be sanitized by replacing all the `.` or space by `_` GraphiteEmitter.sanitize(String)
