Class RRDWriter

java.lang.Object

com.googlecode.jmxtrans.model.output.BaseOutputWriter

com.googlecode.jmxtrans.model.output.RRDWriter

All Implemented Interfaces:

OutputWriter, OutputWriterFactory, AutoCloseable

public class RRDWriter
extends BaseOutputWriter

This takes a JRobin template.xml file and then creates the database if it doesn't already exist. It will then write the contents of the Query (the Results) to the database. This uses the JRobin rrd format and is incompatible with the C version of rrd.
