I personally have found it useful to see time in the Solr log include milliseconds, but it is no longer included, even in 3.6.1.
Actually, I do see it in the first few log entries, but then the log format changes: 2012-08-17 10:41:35.826:INFO:oejsh.ContextHandler:started o.e.j.w.WebAppContext{/solr,file:/C:/cygwin/home/projects/apache-solr-4.0.0-BETA/apache-solr-4.0.0-BETA/example-books/solr-webapp/webapp/},C:\ cygwin\home\projects\apache-solr-4.0.0-BETA\apache-solr-4.0.0-BETA\example-books/webapps/solr.war Aug 17, 2012 10:41:35 AM org.apache.solr.core.SolrResourceLoader locateSolrHome INFO: JNDI not configured for solr (NoInitialContextEx) I much prefer the initial header format: 2012-08-17 10:41:35.826:INFO:oejsh.ContextHandler:started To the revised header format: Aug 17, 2012 10:41:35 AM org.apache.solr.core.SolrResourceLoader locateSolrHome INFO: Oh, and it looks like every log entry in the new format occupies TWO lines. Was this a conscious and Solr community-consensus decision, or just an inadvertent side effect of updating log jars? Can we get the old format back? Thanks. -- Jack Krupansky
