Hi, for multiple-process HAProxy installation we recommend using plugins socket mode.  
All You need to do there is specify one stats socket for each HAProxy process.  
[HAProxy extension — Dynatrace Docs](https://www.dynatrace.com/support/help/technology-support/monitoring-support/how-do-i-configure-haproxy-monitoring/) here you are, usage example.
