Filebeat - first setup

Elastic Stack Logstash
1

Hello, Im trying to setup my first test site.

This is my filebeat.yml
filebeat.prospectors:
- input_type: log
    - /var/log/*.log
    - /var/log/auth.log
output.logstash:
  # The Logstash hosts
  hosts: ["172.23.253.24:5043"]

my logstash config:
/etc/logstash/conf.d$ cat first.conf
input {
beats {
port => "5043"
}
}
output {
elasticsearch {
hosts => ["172.23.253.23:9200"]
protocol => "http"
}
}

My /var/log/filebeat/filebeat logfile:

On logstash server I have also installed ./logstash-plugin install logstash-input-beats

I am running
ubuntu 16.04.1
logstash 5
filebeat 5
installed from repository

It looks like Logstash on 172.23.253.24 isn't actually listening on port 5043 (check with netstat), or maybe the port is blocked by a firewall.

3

yes I checked its open
olof@80003v-app002:/etc/filebeat$ netcat -z -v 172.23.253.24 5043
Connection to 172.23.253.24 5043 port [tcp/*] succeeded!

4

Restarted both services.

on logstash:

@80003v-app004:/etc/logstash/conf.d# netstat -ln | grep 5043
tcp6       0      0 :::5043                 :::*                    LISTEN
