Hi, Im a beginner with ELK and I want to apply different filter on my log.  
This is my input file :  
input {  
beats {  
type =\> log  
port =\> 5044  
host =\> 0.0.0.0  
}  
}  
With this file, we listen on port 5044, from everywhre, and each log we received on this port will have the log type. Are we ok ?

Now if i receive Apache log on this port, and Syslog too for example, how can I filter filter them. I mean how in the filter I can take only apache log, or only log file ?

And when I used filebeat modules, should I have to create by my self a filter file ?

Sorry for bad english and thank you.

[This](https://discuss.elastic.co/t/if-condition-in-logstash-filter-not-working/164577) thread has an example of making adding fields to a record in filebeat and using conditionals in the filter in logstash.

Hi and thanks.

When I have this input :

```auto
filebeat.inputs:
- type: log
  paths:
    - /var/log/auth1.log
  fields:
    log_type: auth1
  fields_under_root: true
- type: log
  paths:
    - /var/log/auth2.log
  fields:
    log_type: auth2
  fields_under_root: true

```

My filter file will start like :  
filter {  
if [log\_type] == "auth1" {  
grok { blabla }  
}  
}

This will be ok ?
