Multi Process Workers doesn't work

[vkakhnych]

We have a simple config:

<system>
  workers 4
</system>

<source>
  @type beats
  bind 127.0.0.1
</source>

But running top I see load on the only one worker. It hits 100% CPU consuming and we're loosing logs.

top - 11:17:00 up 324 days, 16:45,  1 user,  load average: 13.00, 11.62, 10.53

UPD: No any additional listener in the system:

[root@batch01 ~]# netstat -natp | grep 504[4-9]

Ok, I might misunderstood multi workers approach. Get it worked after adjusting config:

<system>
  workers 4
</system>

<worker 0>
  <source>
    @type beats
    bind 127.0.0.1
  </source>
</worker>

<worker 1>
  <source>
    @type beats
    bind 127.0.0.1
  </source>
</worker>

<worker 2>
  <source>
    @type beats
    bind 127.0.0.1
  </source>
</worker>

<worker 3>
  <source>
    @type beats
    bind 127.0.0.1
  </source>
</worker>

And added these hosts/ports to filebeat config accordingly.
