Filebeat multiline pattern with linefeed

Elastic Stack Beats
1

Dear all,

i try to match a multiline java - event in Filebeat via multiline pattern. In general, this is still working, but i´m not able to parse empty lines in this event. The String looks like this:

BMC:SR:2019-08-01 07:37:00:ERROR (TaskScheduler:run) - Error checking system schedules:

    ... 6 more

and my RegEx is:
'^[[:space:]]|^Caused by:|^java|^org|^com'

i also tried
'^[[:space:]]|^Caused by:|^java|^org|^com|^$'

but this doent work at all.

The shown character in this logevent (:set list in vi) ist "$".

Are there any ideas how to fix this?

Thanks a lot

Hmm, can you share your filebeat.yml configuration? Specifically the multiline parts.
According to the Go playground, your regex should work fine, with the '^$' capturing the empty line:
