I had the same problem. I'd be very interested to know how to get this working...

Here is our setting: <!-- To aid in advanced debugging, you may turn on IndexWriter debug logging. Uncommenting this and setting to true will set the file that the underlying Lucene IndexWriter will write its debug infostream to. --> <infoStream file="/tmp/LuceneIndexWriterDebug.log">true</infoStream> After making that change to solrconfig.xml, restarting Solr, we see a message in the tomcat logs saying that the log is enabled: build-2_log.2009-10-06.txt:INFO: IndexWriter infoStream debug log is enabled: /tmp/LuceneIndexWriterDebug.log However, if we then run an optimize we can't see any log file being written. I also looked at the patch for http://issues.apache.org/jira/browse/SOLR-1145, but did not see a unit test that I might try to run in our system. Do others have this logging working successfully ? Is there something else that needs to be set up? Tom
