I think this is a common problem of at least Java services. You can solve this problem with **fluentd** itself - https://stackoverflow.com/questions/57327257/how-to-parse-multiline-java-error-exception-stack-traces-input-in-fluentd-i-sho - https://github.com/fluent/fluent-plugin-grok-parser/issues/69 It seems that in Log4j2 there is a configurable solution for this. It can also be done in log4j1 (current version in ivy) but it's not that easy to correctly implement it in ivy. https://stackoverflow.com/questions/38486248/how-to-make-log4j-syslog-appender-write-a-stack-trace-in-one-line/55407412#55407412 I recommend to solve it in **fluentd** for now. On our side we plan to upgrade to **log4j2**.
