[logback-user] Logback not rolling

14 Sep 2018

      Hi all

Sorry I know it's an already asked question, but I can't figure out how to
configure logback to solve the problem.
Here is my config:

tomcat 7 under windows server 2012
logback 1.1.7
slf4j 1.7.21
java 7

logback.xml:

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="10 seconds" debug="true">
	<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
		<file>logs\logback.log</file>
		<rollingPolicy
class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
			<fileNamePattern>logs\logback.%i.log</fileNamePattern>
			<minIndex>1</minIndex>
			<maxIndex>20</maxIndex>
		</rollingPolicy>
		<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
			<maxFileSize>10MB</maxFileSize>
		</triggeringPolicy>
		<encoder>
			<charset>UTF-8</charset>
			<pattern>%date [%thread] %-5level %logger - %msg%n</pattern>
		</encoder>
	</appender>

	<logger name="it.infoline" level="WARN" />
	<logger name="org.flywaydb" level="OFF" />
	<logger name="it.infoline.ouverture.data.LogonDatabase" level="DEBUG" />

	<root level="WARN">
		<appender-ref ref="FILE" />
	</root>
</configuration>

Enabling logback debug I've seen that the root cause is the renaming:

16:05:55,728 |-INFO in c.q.l.co.rolling.helper.RenameUtil - Renaming file
[logs\logback.log] to [logs\logback.1.log]
16:05:55,728 |-WARN in c.q.l.co.rolling.helper.RenameUtil - Failed to rename
file [logs\logback.log] as [logs\logback.1.log].
16:05:55,729 |-WARN in c.q.l.co.rolling.helper.RenameUtil - Please consider
leaving the [file] option of RollingFileAppender empty.
16:05:55,729 |-WARN in c.q.l.co.rolling.helper.RenameUtil - See also
http://logback.qos.ch/codes.html#renamingError

The solution in the link (http://logback.qos.ch/codes.html#renamingError)
doesn't work with FixedWindowRollingPolicy if I understand well, right ?

So I tried something like this:

	<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<fileNamePattern>C:\Infoline\WebAppConfig\log.%d{yyyy-MM-dd}.log</fileNamePattern>
			<maxHistory>30</maxHistory> 
			<totalSizeCap>3GB</totalSizeCap>			
		</rollingPolicy>
		<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
			<maxFileSize>1KB</maxFileSize>
		</triggeringPolicy>
		<encoder>
			<charset>UTF-8</charset>
			<pattern>${HOSTNAME} %date [%thread] %-5level %logger >%X{ILSID}< -
%msg%n</pattern>
		</encoder>
	</appender>

With this configuration I didn't understand where the log will go.
Without file option, how can I tell logback which file to use? 

Sorry for the trivial question but it seems I can't find a solution myself
thanks in advance
Nicola
