This indicates that your configuration contains more than one beats input listening on the same port. You can't have that.

Use a `stdout { codec => rubydebug }` output and comment out your elasticsearch output. Are you getting anything in the log? If not, raise Logstash's log level to debug (there's a command line option for it, see the docs) and try again.

Since you're still not getting any events the next course of action would be to raise the log level.

curl -XPUT 'localhost:9600/_node/logging?pretty' -H 'Content-Type: application/json' -d'

    "logger.logstash.outputs.elasticsearch" : "DEBUG"

Changing the loglevel of the logger.logstash.outputs.elasticsearch logger is useless when you're not using that plugin. It's the logstash.input.exec logger that's interesting. However, I was actually thinking about the global loglevel (that can be changed via a command-line option) but in this case I'm mostly interested in what the exec plugin logger says.

Set this in your logstash.yml

```
log.level: debug

```

or use '--log.level debug' on the command line.

Please look in a log after turning on a debug. I wrote it in another message

Can you comment out the codec on the input? Your script prints commentary on what it is doing, so its output is not JSON.

> Yes, still nothing showing in Kibana.

No, of course not since the elasticsearch output has been commented out. Once we get Logstash to produce the events we can enable that output again.

I suspect the codec needs to be json\_lines rather than json.

My logstash.yml after comment out

```
input {
  exec {
        command => "/usr/bin/python /home/maksym/PathFolder/pythonpractice/postsample.py"
        interval => 20
        #codec => "json_lines"
        } 
}

output {
  # elasticsearch {
# hosts => ["localhost:9200"]
# index => "logstash-%{+YYYY.MM.dd}"
#}
   stdout { 
     codec => rubydebug
   }
}
