I’m new to solr and not very good with java.
we are using solr as our search solution and tomcat is hosted as a service in windows and solr is runs in tomcat.
We are trying to implement log rotation for tomcat. We tried using log4j.properties in and logging.properties. But for sine reason the stdout and stderr are still piling up and are consuming a lot of space.
We are using log4j.properties to rotate solr logs.
Grateful if we could get some help for rotating stdout and stderr logs.
We have tried 3 different methods and none of them worked as expected.
Added stdout to log4j.properties
solr.log=logs/ log4j.rootLogger=ERROR, stdout
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x \u2013 %m%n
size rotation with log cleanup.
log4j.appender.stdout=org.apache.log4j.RollingFileAppender log4j.appender.stdout.MaxFileSize=4MB log4j.appender.stdout.MaxBackupIndex=9
- File to log to and log format
log4j.appender.stdout.File=${solr.log}/solr.log log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%-5p - %d{yyyy-MM-dd HH:mm:ss.SSS}; %C; %m\n
Added file size limit to logging.properties in tomcat.
java.util.logging.FileHandler.limit = 2000000 java.util.logging.FileHandler.count = 5
Update the Java properties in Monitor Tomcat applications.
added the below to java option under java tab in tomcat
-Djava.util.logging.FileHandler.limit=25000000
All theese attempts failed and we had to restart the tomcat to rotate the file which is not desirable in production.
Tomcat: 8.0.20
Solr: 4.10.3
OS: Windows
