DNS discovery issue for hosts with same hostname

[xkidro]

Hello!

I have 6 hosts in Rancher currently ( must configure docker on the rest of my 200 compute cluster ) and 3 of them are cloud servers and the other 3 are compute nodes which I would like to monitor.

All my compute nodes have the same hostname.

I only see 4 hosts in Grafana, I figured it has to be the hostname because I recently added a new server specially for Prometheus, previously I had only 2 servers and 3 compute nodes and I only saw 3 hosts.

Is there something I can do so that I can see all hosts ?

Thank you1
