Thanks, Ciprian. I ran rsyslogd -dn and I can see that imfile is reading
changes from cassandra.log, but it's not sending them to elasticsearch
until I restart. Thoughts?

Rsyslog trace before restart doesn't have any omelasticsearch logs:
...

Rsyslog after restart which causes logs to be sent to elasticsearch:
...

there should be something in the logs about the elasticsearch action, do you have it named? (name= in the action statement)

are you saying that when rsyslog starts, it doesn't send, but if you restart it, it then sends normally? or are you saying that nothing goes through until you do a restart, then onebatch of messages get through and nothing beyond that until you do a restart again?
