How to consolidate multiline logs in syslog using log4j

I upload my var / log / message file with rsyslog to the tool. But, since you can see that the exception appears in several lines (different timestamps for each line), and is not registered as one line. I would like it to be like catalina.out post. Is there any way to achieve this. Any help would be appreciated.

catalina.out is as follows:

var / log / message is as follows
