How set filebeat output logstash speed limit?

I use Filebeat and logshtash, But I worry most of message use high NET_OUT_BITPS, and affect online business. :sweat:

You cannot slow filebeat, the only way to do this would be to do something on the network level like QoS.

It is mean Filebeat not known itself output speed (like 3MB/s).

Filebeat will just process things as fast as it can.

Thx, It’s clear to me now.
