I have set-up an ELK server in testing environment. I intend to send log messages from different clients to ELK, but first i want to test it from localhost to verify it running properly.

Previously i had directly , used a python library to interact with elastic-search (since there was a problem in using urllib2 , 400 bad request) , but this time i want to send the message to log-stash and let the log-stash deal with it before it goes to Elastic Search.

I used netcat , but there is some problem with the port number:

  echo "access denied" | nc localhost 5514
  Ncat: Connection refused.

Seems like there is nothing on this port. The logstash service is running.

You could use logger with the -P switch to set your port to 5514.

Check man logger for other suitable switches, eg -t.

echo "access denied" | logger -t myservice -P 5514

To check if port 5514 is currently associated with logstash, lsof -i :5514, or check logstash startup logs (meta!). Are you certain your logstash is using that particular port?
