The Flume appender can persist messages within the same process to files
before sending them to other agents. I don't think any other appender can
guarantee that.

Personally, I've been using direct console appenders lately and using
graylog to slurp stdout on docker containers, but I'm not the one who set
all that up. Either way, the most reliable way to log things outside of
files is Flume.
