我正在测试ESB 4.9.0和BAM 2.5.0，并尝试按照此文档https://docs.wso2.com/display/Carbon442/Publishing+Logs+to+BAM将ESB日志发布到BAM，但在启动ESB实例时报告了错误。

当我试图在org.wso2.carbon.logging.service_4.4.7.jar中找到logeventappender时，无法找到它。这个appender可以在之前发布的ESB 4.8.1的org.wso2.carbon.logging.service_4.2.0.jar中找到。
如果此功能仍在4.9.0中使用，有人可以帮我设置吗？
答案 0 :(得分：3)
ESB 4.9.0和BAM 2.5.0将不再支持此功能。因为两者都取决于两种不同的碳版本。
ESB 4.9.0取决于碳4.4.0，BAM 2.5.0取决于4.2.0。
WSO2现在对BAM进行了解密，并推出了一款名为Data Analytics Server的新产品，该产品为revamp of old BAM with more additional features。
您可以使用DAS 3.0.0的Logging Agent功能和ESB 4.9.0
