Label for host separation per request

[izaacmenezes]

Good morning, I am using two projects connected to each other, heplify-server-master/docker/hep-prom-graf and homer7-docker-master/heplify-server/hom7-prom-all, where, in hep-prom- graf I use prometheus, alertmanager, nodeexporter, grafana and caddy, while in hom7-prom-all I use heplify-server, loki, homer-app with db postgres:11-alphine;

The environment is functional, however, in the hep-prom-graf project, it appears as queries in general, without separation by received host, there is no label for separation by source IP or even destination IP, in this case, what is the best Output to a label where I can separate this data? I tried via HEPLIFYSERVER-PROMTARGETIP and HEPLIFYSERVER-PROMTARGETNAME, but without success, it doesn't return data
