Summary: Multiple log files being created for rolling log4j2 conf
in IBM Websphere
Key: LOG4J2-1754
URL: https://issues.apache.org/jira/browse/LOG4J2-1754
Project: Log4j 2
Issue Type: Question
Components: Appenders
Affects Versions: 2.6.2, 2.5
Environment: IBM Websphere,
java-1.8.0-ibm-1.8.0.3.20-1,
IBM Iseries,
log4j2 2.5, log4j 2.6.2
Reporter: prayagupd
When I am testing my logs in IBM server with websphere 8, I see multiple log
files created at the same time, I don't know what's the logic behind it. My
logrotate config is for 100MB upto 10 files.
My config is
{
"configuration": {
"name": "logggg",
"appenders": {
"RollingFile": {
"name": "rollingFile",
"fileName": "/var/log/app/test_logging.log",
"filePattern":
"/var/log/app/test_logging-%d{MM-dd-yy-HH-mm-ss}-%i.log.gz",
"JSONLayout": {
"complete": false,
"compact": true,
"eventEol": true
},
"SizeBasedTriggeringPolicy": {
"size": "100 MB"
},
"DefaultRolloverStrategy": {
"max": "10"
}
}
},
"loggers": {
"root": {
"level": "DEBUG",
"appender-ref": {
"ref": "rollingFile"
}
}
}
}
}
I haven't seen this problem in Tomcat server on Linux server.
Example, there's test_logging.10 and test_logging.log less than 100M

After 10 mins, I see it only appending to the test_logging.log.
