I am running Graylog, Logstash, Elastic and mongodb with a docker-compose file that i found and crafted to use logstash as well.
The original is here
i have just added logstash and connected.
But i managed to ship my logs from a remote machine, all seem to work but graylog journal gives the following
-92,807 unprocessed messages are currently in the journal, in 1 segments.
17 messages have been appended in the last second, 0 messages have been read in the last second.
It does not proccess the messages.
