Logstash service keeps dying - no logs

[carlfriedrichgauss]

Trying a new ELK stack install against RHEL 7. Java on openjdk version "1.8.0_144"

I'm installing an older version (this is an absolute requirement) and used the logstash-2.1.3-1.noarch.rpm package. ES is up and running as a service and I can curl 9200.

I've made 1 super simple config file:

cat /etc/logstash/conf.d/test.conf
input { stdin { } }
output { stdout {} }

I try to start the logstash service and it starts, and then takes about 5 seconds to fail with no errors. It just goes from "running" to "not running." All the logs are empty (and owned by logstash:logstash).

can you do a configuration like

input { generator { count => 1 } tcp { port => 3333 } }
output { file { path => "/tmp/test.log"} }

and see if logstash stays up and writes data to that file?

That worked to get the process running. What was wrong with my conf file?
