LogDataSink

The LogDataSink puts each record into the log file. It is possible to specify a set of messages to be logged or to log the complete output data. If no log name is specified, the data is written to the standard error output.

Configuration

Name	Type, usage constraints, defaults	Description
log	required: paraVal default: none type: string	The name of the log. By default, the standard error output is used.
messages	optional: paraList default: none type: list of strings	Defines the messages to be written to the log. By default, the full data of the output object is written.
timeExports	optional: paraVal default: none type: integer	Defines after how many exports timing information should be written to the log file.

Example

Print output object to the standard error output.

<dataSink type="LogDataSink" />

Log some messages to the logger "mylogname" defined in log4j.xml.

<dataSink type="LogDataSink" >
  <dp:paraVal name="log" value="mylogname"/>
  <dp:paraList name="message">
    <value>Message1</value>
    <value>Name: #{in.user.name}</value>
  </dp:paraList>
</dataSink>

Log the time it takes to export 1000 objects.

  <dp:paraVal name="timeExports" value="1000"/>
