在WSO2中，ESB 4.5.1在repository / logs文件夹中有several log file。但是一个重要的“wso2carbon.log”只包含一天的整个日志。然后在午夜它被冲洗了。 因为同一目录中的其他日志文件（wso2-esb-service.log或http_access.log）具有此功能，所以保留了几天。
如何保留wso2carbon.log文件几天？ （WSO2应该只重命名它们，而不是删除它们。）

您的配置看起来不错，它应该在每天结束时轮换您的日志文件。如果您是Windows用户，则报告了旋转问题[1]。这已在最新的碳包中修复
答案 1 :(得分：0)
您应该能够使用每日滚动日志的“DailyRollingFileAppender”并将其保存在命名模式为“wso2carbon.yyy-mm-dd.log”的同一文件夹中。我相信这是默认情况下作为任何Carbon产品（包括WSO2 ESB）的log4j配置中的wso2carbon.log文件的附加程序附加的选项。

我使用每天23:59运行的任务创建了自己的文件备份。好吧，我会丢失一分钟的日志，但这比丢失整个文件要好。
