Description of problem:
RHELPLAN-56797 - Logging - RFE - support property-based filters in the files and forwards outputs
In an rsyslog.conf file I would use the following:
:msg, startswith, "somefilter" -/var/log/output.log
Rsyslog doc: https://www.rsyslog.com/doc/v8-stable/configuration/filters.html
Upstream CI test cases are available in https://github.com/linux-system-roles/logging/blob/master/tests/tests_basics_files2.yml.
As described in #c1, there is a test case in the upstream CI to verify this bug.
Could you give a qa_ack+?
