Here, here we choose filebeat as input in logstash, because the source is "journald" binary logs. And choose file as output in logstash. Logstash service and configure seem ok. Filebeat input port is working also. But just no incoming data and no file created in output side. When I switch "elasticsearch" as output in logstash, I can see created indice from api or kibana. So my question is whether "journald" binary logs support render and can be converted to plain text by codec in file mode output. If not, any other verified output support besides elasticsearch output in logstash. Thanks.
