WSO2 ESB：幾天后還備份wso2carbon.log文件？

Question

在WSO2中，ESB 4.5.1在repository / logs文件夾中有幾個日志文件 。 但是一個重要的“wso2carbon.log”只包含一天的整個日志。 然后在午夜它被沖洗了。 因為同一目錄中的其他日志文件（wso2-esb-service.log或http_access.log）具有此功能，所以保留了幾天。

我怎么能保留wso2carbon.log文件幾天？ （WSO2應該重命名它們，而不是刪除它們）。

這是我在conf目錄中的log4j.properties：

Answer 1

您的配置看起來沒問題，它應該在每天結束時輪換您的日志文件。 如果您是Windows用戶，則報告了旋轉問題[1]。 這已在最新的碳包中得到修復

[1] - https://wso2.org/jira/browse/ESBJAVA-1614

Answer 2

您應該能夠使用“DailyRollingFileAppender”，它每天滾動日志並將其保存在命名模式為“wso2carbon.yyy-mm-dd.log”的同一文件夾中。 我相信這是默認情況下作為任何Carbon產品（包括WSO2 ESB）的log4j配置中的wso2carbon.log文件的附加程序附加的選項。

Answer 3

我使用每天23:59運行的任務創建了自己的文件備份。 好吧，我會丟失一分鍾的日志，但這比丟失整個文件要好。
