Shawn Heisey commented on SOLR-5277: ------------------------------------ Some 'thinking out loud': The fact that newly spawned threads inherit the MDC is awesome. It can be fairly minimal or really verbose if we add to it based on whether certain logging levels are enabled. > Stamp core names on log entries for certain classes > --------------------------------------------------- > > Key: SOLR-5277 > URL: https://issues.apache.org/jira/browse/SOLR-5277 > Project: Solr > Issue Type: Bug > Components: search, update > Affects Versions: 4.3.1, 4.4, 4.5 > Reporter: Dmitry Kan > Attachments: SOLR-5277.patch > > > It is handy that certain Java classes stamp a [coreName] on a log entry. It > would be useful for multicore setup if more classes would stamp this > information. > In particular we came accross a situaion with commits coming in a quick > succession to the same multicore shard and found it to be hard time figuring > out was it the same core or different cores. > The classes in question with log sample output: > o.a.s.c.SolrCore > 06:57:53.577 [qtp1640764503-13617] INFO org.apache.solr.core.SolrCore - > SolrDeletionPolicy.onCommit: commits:num=2 > 11:53:19.056 [coreLoadExecutor-3-thread-1] INFO > org.apache.solr.core.SolrCore - Soft AutoCommit: if uncommited for 1000ms; > o.a.s.u.UpdateHandler > 14:45:24.447 [commitScheduler-9-thread-1] INFO > org.apache.solr.update.UpdateHandler - start > commit{,optimize=false,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=true,prepareCommit=false} > 06:57:53.591 [qtp1640764503-13617] INFO org.apache.solr.update.UpdateHandler > - end_commit_flush > o.a.s.s.SolrIndexSearcher > 14:45:24.553 [commitScheduler-7-thread-1] INFO > org.apache.solr.search.SolrIndexSearcher - Opening Searcher@1067e5a9 main > The original question was posted on #solr and on SO: > http://stackoverflow.com/questions/19026577/how-to-output-solr-core-name-with-log4j -- This message was sent by Atlassian JIRA (v6.1#6144) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
