Hi

I have been using a ELK stack now for nearly a year. I have noticed that my logstash is no longer sending data to ES/Kibana, It looks like the issue started about a month ago (worked fine until then)

I am using a single node setup, which collects logs locally (no filebeat)

Logstash is running -  
[logstash.agent] Successfully started Logstash API endpoint {:port=\>9600}

Logstash also seems to off stopped logging to /var/log/logstash in around march, exept occasionly. (The data is also inconsitent), There is for example 400 hits on 20/05/2019 but if i cat | wc -l the logs there should be over 10k+.

Elastic search is running -  
curl -v [http://localhost:9200](http://localhost:9200)

- Rebuilt URL to: [http://localhost:9200/](http://localhost:9200/)
- Trying 127.0.0.1...
- TCP\_NODELAY set
- Connected to localhost (127.0.0.1) port 9200 (#0)

> GET / HTTP/1.1  
> Host: localhost:9200

"minimum\_index\_compatibility\_version" : "5.0.0"  
},  
"tagline" : "You Know, for Search"  
}

- Connection #0 to host localhost left intact

I am pretty sure the logstash logs should be full of information, but it doesnt seem to be doing anything.

I don't really know where to start in diagnosing this, can someone point me in the right direction?
