HI Everyone  
I want to test how many clients(similar) can my currently setup Logstash server handle.  
I need to increase the number of servers on which filebeat agent will be installed which will be sending data at a constant rate to the Logstash.  
How can I determine the number of agents it can consume data from without failing. Please suggest any testing tool or API to simulate load on Logstash.

Hello.  
Have a look on: [https://github.com/elastic/logstash/tree/master/tools/benchmark-cli](https://github.com/elastic/logstash/tree/master/tools/benchmark-cli)

This benchmark tool doesn't allows me to simulate load on logstash pipeline. Please suggest how to to that and test breakpoint of my Logstash server.

I know about two options:

1. [https://www.elastic.co/guide/en/logstash/current/node-stats-api.html](https://www.elastic.co/guide/en/logstash/current/node-stats-api.html)
2. Enable monitoring for your logstash and monitor the performance in Kibana.
