[logback-user] 回复： maxIndex issue

[陌路人]

The max index can not greater than 20, hardcode, in FixedWindowRollingPolicy.java



    /**
     * It's almost always a bad idea to have a large window size, say over 20.
     */
    private static int MAX_WINDOW_SIZE = 20;

does '200KB' is effective? every file part size is '200KB'?

Hi all,

I have my rollingFileAppender configured as follows:


appender("myAppender", RollingFileAppender) {
        file = "${logDir}/myApp.log"
        encoder(PatternLayoutEncoder) {
            charset = Charset.forName('UTF-8')
            pattern = log_pattern
        }
        rollingPolicy(FixedWindowRollingPolicy) {
            fileNamePattern = "${logDir}/myApp%i.log"
            minIndex = 1
            maxIndex = 24
        }
        triggeringPolicy(SizeBasedTriggeringPolicy) {
            maxFileSize = FileSize.valueOf("200KB")      
        }
    }



I had first the maxIndex = 20, i modified it to 24 and I'm testing. As I see the number of logs are 21 and rotating while it should be 24! I tested it a lot and still the same issue. Anybody has this issue before or knows why this is happening?


Thanks in advance,
Joud
