Solr 7.2 solr.log is missing

Abhi Basu
Not located in the /server/logs/ folder.

Have these files instead

solr-8983-console.log
solr_gc.log.0.current

I can see logs from the Solr dashboard. Where is the solr.log file going
to? A search of "solr.log" in the system did not find the file.

Is the file called something else for solrcloud mode?

log4j.properties shows this:

# Default Solr log4j config
# rootLogger log level may be programmatically overridden by
-Dsolr.log.level
solr.log=${solr.log.dir}
log4j.rootLogger=INFO, file, CONSOLE

# Console appender will be programmatically disabled when Solr is started
with option -Dsolr.log.muteconsole
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.EnhancedPatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSS}
%-5p (%t) [%X{collection} %X{shard} %X{replica} %X{core}] %c{1.} %m%n

#- size rotation with log cleanup.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.MaxFileSize=4MB
log4j.appender.file.MaxBackupIndex=9

#- File to log to and log format
log4j.appender.file.File=${solr.log}/solr.log
log4j.appender.file.layout=org.apache.log4j.EnhancedPatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss.SSS}
%-5p (%t) [%X{collection} %X{shard} %X{replica} %X{core}] %c{1.} %m%n

# Adjust logging levels that should differ from root logger
log4j.logger.org.apache.zookeeper=WARN
log4j.logger.org.apache.hadoop=WARN
log4j.logger.org.eclipse.jetty=WARN
log4j.logger.org.eclipse.jetty.server.Server=INFO
log4j.logger.org.eclipse.jetty.server.ServerConnector=INFO

# set to INFO to enable infostream log messages
log4j.logger.org.apache.solr.update.LoggingInfoStream=OFF


Thanks,

Abhi

Technically, Solr doesn't name the file at all, that's in your log4j
config, this line:

log4j.appender.file.File=${solr.log}/solr.log

so it's weird that you can't find it on your machine at all. How do
you _start_ Solr? In particular, to you define a system variable
"-Dsolr.log=some_path"?

And also note that there are three log4j configs, and it's easy to be
using one you don't think you are using, see SOLR-12008.

Best,
Erick

Re: Solr 7.2 solr.log is missing

Abhi Basu
Wow life is complicated :)

Since I am using this to start solr, I am assuming the one in
/server/scripts/cloud-scripts is being used:
./bin/solr start -cloud -s /usr/local/bin/solr-7.2.1/server/solr/node1/solr
-p 8983 -z zk0-esohad:2181,zk1-esohad:2181,zk5-esohad:2181 -m 10g

So, I guess I need to edit that one.

Thanks,

Abhi
