Its probably there is something wrong with your pipeline, probably the output config file. There can be a missing "{" or "}" thats not good either; WARNING: Could not find logstash.yml which is typically located in $LS\_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console You may need to start logstash with --path \*.yml ---
