@Pavan Challa I've created a template [1] that sketches out how to satisfy your use case. In it I used an ExecuteScript [2] to evaluate the attribute expression from the to.path in the XML file. I do think it'd be better/easier/more perspicuous to just set the directory in PutFile as `/var/tmp/${country}/${datasource}/csv` but figured it was worth showing you how you could do this anyway. The (default) expression engine for the lookups [3] is rather simple so you can't do conditional lookups like you're suggesting, but you can, however, do what you want using the index of the properties. There is a way to enable XPath in the underlying libraries but that'll require some internal code changes and won't help you immediately. 1. https://gist.github.com/jfrazee/26deffba3a7d50e991495e223a020b93#file-lookupattribute_xml_putfile_example-xmllookupattribute_xml_putfile_example-xml 2. https://gist.github.com/jfrazee/26deffba3a7d50e991495e223a020b93#file-evalexp-groovy 3. http://commons.apache.org/proper/commons-configuration/apidocs/org/apache/commons/configuration2/tree/DefaultExpressionEngine.html ...

The memory pool names are specific to whatever garbage collector you're using with the JVM. If you're using ParallelGC the choice of names are going to be: PS Eden Space PS Survivor Space PS Old Gen PS Perm Gen For G1GC: G1 Eden G1 Survivor G1 Old Gen G1 Perm Gen And there are others for other garbage collectors. If you're unsure you can connect to a process using jconsole and look at java.lang -> MemoryPool: ... View more
