FixedWindowRollingPolicy Introduction

The following is about FixedWindowRollingPolicy Introduction to , As shown below :

 FixedWindowRollingPolicy The function of :  According to the fixed window algorithm rename the file rolling strategy . 

FixedWindowRollingPolicy attribute

minIndex: Minimum window index 
maxIndex: Maximum window index , When the window specified by the user is too large , Will automatically set the window to 20
fileNamePattern: Must contain “%i” for example , Suppose that the minimum and maximum values are respectively 1 and 2
    The naming pattern is  myjava265log%i.log, There will be an archive myjava265log1.log and myjava265log2.log
   You can also specify file compression options , Such as :myjava265log%i.log.gz  Or not myjava265log%i.log.zip

example

<!--  Set to scroll by index , When defining the file name, use %i As placeholder , After scrolling, it will be replaced with a corner mark  -->
<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
    <fileNamePattern>/logback/log/test-%i.log</fileNamePattern>
    <minIndex>1</minIndex>
    <maxIndex>3</maxIndex>
</rollingPolicy>
<!--  Specify the maximum file size , Reach this size , It triggers rollingPolicy The corresponding strategy ,maxFileSize Property specifies the file size  -->
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
	<maxFileSize>1MB</maxFileSize>
</triggeringPolicy>
