How to capture senders IP/Hostname in OTEL Collector

[dhaneshdlal]

Hi Team,

I am looking for a solution to capture senders IP/Hostname at collector Gateway. I have a clustered application which has multiple containers running behind load balancers. All are sending metrics with same name and timestamp hence getting "Duplicate sample for timestamp" ( I am not able to add additional label at source level)..Is there any way to capture IP/Host of the sender system so that I can add it as an extra label prior to sending to Prometheus.

Is there any other better way to do this.
