[beats receivers] host parsing failed for prometheus-collector: error parsing URL: parse "http://localhost:EDOT_COLLECTOR_METRICS_PORT": invalid port ":EDOT_COLLECTOR_METRICS_PORT" after host #11169
Description
- Version: 9.2.1
- Operating System: Windows Server 2019 Standard
This was supposed to be fixed in #10819 but we have a bug report that this is still happening in 9.2.1 now that the otel runtime is the default for self-monitoring in 9.2.1

name: beat-v2-clientInterestingly the prometheus/metrics-monitoring input here is running as a sub-process. I think this is likely because we fell back to using the process runtime because the user is using the Kafka output:
