Subject [jira] Updated: (SOLR-1145) Patch to set IndexWriter.defaultInfoStream from solr.xml
Date Thu, 21 May 2009 21:49:45 GMT


Chris Harris updated SOLR-1145:

    Attachment: SOLR-1145.patch

I found it confusing not to have any timestamp data in the infostream log. This new version
prints a timestamp along with each infoStream message. You can configure the timestamp format,
though there's currently no way to disable timestamping.

> Lucene IndexWriters use an infoStream to log detailed info about indexing operations
for debugging purpose. This patch is an extremely simple way to allow logging this info to
a file from within Solr: After applying the patch, set the new "defaultInfoStreamFilePath"
attribute of the solr element in solr.xml to the path of the file where you'd like to save
the logging information.
> Note that, in a multi-core setup, all cores will end up logging to the same infoStream
log file. This may not be desired. (But it does justify putting the setting in solr.xml rather
than solrconfig.xml.)
