Hi everyone,  
I have tried several configurations in the filebeat service but I cannot see a good performance. When I use a single input file we can see a high network throutput and logstash and elasticsearch do a good data processing.  
However, when we use multiple intput files for filebeat the overall performance gets worse.  
This is the parameter configuration we are using for multiple filebeat inputs:

filebeat.spool\_size: 6144  
queue.mem:  
events: 131072

#----------------------------- Logstash output --------------------------------  
output.logstash:

# The Logstash hosts

hosts: ["XXXX:5045", "XXXX:5045"]  
loadbalance: true  
worker: 4  
pipelining: 0  
ttl: 2s  
bulk\_max\_size: 4096

Thanks for your help

Could you please share your full configuration formatted using `</>`?

This is my filebeat.yml

> ```
> #=========================== Filebeat inputs =============================
> filebeat.config.inputs:
> enabled: true
> path: inputs.d/*.yml
> reload.enabled: true
> reload.period: 10s
> #============================= Filebeat modules ===============================
> filebeat.config.modules:
> path: ${path.config}/modules.d/*.yml
> reload.enabled: false
> #================================ General =====================================
> filebeat.spool_size: 6144
> queue.mem:
> events: 131072
> #================================ Outputs =====================================
> #----------------------------- Logstash output --------------------------------
> output.logstash:
> hosts: ["X.X.X.X:5045", "Y.Y.Y.Y:5045"]
> loadbalance: true
> worker: 4
> pipelining: 0
> ttl: 2s
> bulk_max_size: 4096
> 
> ```

And I have 12 .yml files under inputs.d folder with this structure:

> ```
> - type: log
> enabled: true
> paths:
> - /folder/log/service/*.log
> fields_under_root: true
> fields: {type: service}
> 
> ```

Thanks

I don't see anything in your configuration which would lead to degraded performance.  
What is your expectation regarding events/sec?  
Could you please provide the debug logs of Filebeat? Do you see any errors in Logstash?

</div>

When I configure one input file for filebeat, I see up to 35Mbps (around 3300 paquets/sec) and when add more files I only get around 1Mbps (70 paquets/sec).

How do I get debug logs for filebeat? filebeat - e - d "\*" ?

I don't get any errors in Logstash.

thanks
