Upgrade Notes
|
||||
----------------------
|
||||
|
||||
* SOLR-7887: Solr now uses Log4J 2.11. The log4j configuration is now in log4j2.xml rather than lo4j.properties files
|
||||
* SOLR-7887: Solr now uses Log4J 2.11 . The log4j configuration is now in log4j2.xml rather than log4j.properties files.
|
||||
This is a server side change only and clients using SolrJ won't need any changes. Clients can still use any logging
|
||||
implementation which is compatible with SLF4J.

||||
|

Solr uses http://logging.apache.org/log4j/{ivy-log4j-version}/[Log4J version {ivy-log4j-version}] for logging which is configured using `server/resources/log4j2.xml`. Take a moment to inspect the contents of the `log4j2.xml` file so that you are familiar with its structure. By default, Solr log messages will be written to `SOLR_LOGS_DIR/solr.log`.

When you're ready to deploy Solr in production, set the variable `SOLR_LOGS_DIR` to the location where you want Solr to write log files, such as `/var/solr/logs`. You may also want to tweak `log4j2.xml`. Note that if you installed Solr as a service using the instructions provided in <<taking-solr-to-production.adoc#taking-solr-to-production,Taking Solr to Production>>, then see `/var/solr/log4j2.xml` instead of the default `server/resources` version.

Java Garbage Collection logs are rotated by the JVM when size hits 20M, for a max of 9 generations. Old GC logs are moved to `SOLR_LOGS_DIR/archived`. These settings can only be changed by editing the start scripts.
|
||||
|
||||
On every startup of Solr, the start script will clean up old logs and rotate the main `solr.log` file. If you changed the `log4j.appender.file.MaxBackupIndex` setting in `log4j2.xml`, you also need to change the corresponding setting `-rotate_solr_logs 10` in the start script.

On every startup of Solr, the start script will clean up old logs and rotate the main `solr.log` file. If you changed the `<DefaultRolloverStrategy max="10"/>` setting in `log4j2.xml`, you also need to change the corresponding setting `-rotate_solr_logs 10` in the start script.
|
||||
|
||||
You can disable the automatic log rotation at startup by changing the setting `SOLR_LOG_PRESTART_ROTATION` found in `bin/solr.in.sh` or `bin/solr.in.cmd` to false.
