Grafana server IP change

[Hemedi Salim]

Hi Lads,

I am a bit new in this field. I have implemented a grafana server with prometheus and alertmanager install and all works fine. But now we are thinking of  moving from the subnet where the grafana and prometheus are installed to a new subnet (to change IP address).

my question is does anybody have an idea on this or Does the changing IP address affect the operation of prometheus and grafana?

(all prometheus and grafana are install in one vm)

Thanks in advance

Prometheus doesn't care what IP address it listens on, and as far as I know nor does Grafana.  If they are running in the same VM, and Grafana is pointing to http://127.0.0.1:9090 to query Prometheus, then it won't even notice the change.

The things which will will make a difference are:

- if you change the IP addresses of the targets that are being scraped

- if the targets are using firewall rules or ACLs to accept scrapes only from a particular IP address

- if the targets are configured to use Remote Write to connect actively to the Prometheus server on its IP address (this is a relatively unusual configuration)

- if anything else connects to Prometheus to query it

Issues about Grafana specifically would best be addressed to the Grafana community.

Thanks, very much. I got it.
