这是一个示例日志:
2022-01-07 11:05:01,185 [http-nio-8080-exec-526] WARN de.web.Main| = - Error while execute Request

这是目前的模式: ^.*?Exception: +%{DATA:exception}$
我得到的 output 很接近,但没有雪茄: "com.cg.blart.web.HttpInvocationException: Invalid tenant session"
。 对于我的生活,我无法让它与整条线相匹配。 你能给我指路吗? The desired output is: javax.servlet.ServletException: com.cg.blart.web.HttpInvocationException: Invalid tenant session
这是测试工具的链接: https://grokdebug.herokuapp.com/
解决方案是这种模式:
(?<DATA:mps_exception>.*?(Exception:).*)
