Logstash not outputting logs to elasticsearch

Elastic Stack Logstash
9

It turns out that when I was restarting logstash all of the processes weren't being terminated. My config files weren't the problem.

Here are the commands I ran to solve this:

ps -ef | grep logstash 
sudo kill EACH_PID 
sudo kill -9 PID_THAT_WASNT_KILLED_BEFORE 
sudo /etc/init.d/logstash start

Thank you @magnusbaeck for all of your time and help!
