Class KeyOutWriter

java.lang.Object

com.googlecode.jmxtrans.model.output.BaseOutputWriter

com.googlecode.jmxtrans.model.output.KeyOutWriter

All Implemented Interfaces:

OutputWriter, OutputWriterFactory, AutoCloseable

Direct Known Subclasses:

DailyKeyOutWriter, TimeBasedRollingKeyOutWriter

public class KeyOutWriter
extends BaseOutputWriter

Writes out data in the same format as the GraphiteWriter, except to a file and tab delimited. Takes advantage of Log4J RollingFileAppender to automatically handle rolling the files after they reach a certain size.

The default max size of the log files are 10MB (maxLogFileSize) The default number of rolled files to keep is 200 (maxLogBackupFiles)
