Hi,
I'm using a FileNamePattern with a FixedWindowPolicy:
Here's my appender:
<appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/usr/local/mystro/logs/MSAServer.log</file>
<append>true</append>
<rollingPolicy
class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<FileNamePattern>/usr/local/neil/logs/MSAServer.%i.
%d{yyyyMMdd-HHmmss}.gz</FileNamePattern>
<MinIndex>1</MinIndex>
<MaxIndex>3</MaxIndex>
</rollingPolicy>
<triggeringPolicy
class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<MaxFileSize>1KB</MaxFileSize>
</triggeringPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{ISO8601} %-5level [%thread] \(%logger{0}.%M:%L
\\) - %msg%n</Pattern>
</layout>
</appender>
Here's the exception when the file rolls -- I had to alter the
rollover method of FixedWindowPolicy in order to catch throwable to
see what was going on:
java.lang.IllegalArgumentException: Cannot convert 3 of

Is this an intentional restriction to make the file name pattern have
%i first and then %d?
Thanks,
Neil
