Hi Dublin,

Yes it is definitely possible. @steffens had helped me on an [issue](https://discuss.elastic.co/t/filebeat-slow-improve-performance/144717/3) a couple of years back

The relevant part is as follows:  
simple logstash config for testing:

```auto
input {
  beat { ... }
}

output {
  stdout { codec => dots }
}

```

This config prints one dot per event. Using pv we can measure throughput:

```auto
./bin/logstash test.cfg | pv -War > /dev/null

```

This will give you the event rate in terms of bytes/sec. To get an idea about the actual event rate, you will have to use the [metric filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-metrics.html). Hope this helps! 🙂
