Prometheus scrap source IP address

[Vishal]

Hello,

In our setup, a Prometheus on node 1 scraps from Prometheus on nodes 2 and 3.

Node 1 has 2 IP addresses (.175 and .176) on eth1.

Is it possible for us to select the source IP address anywhere in Prometheus configuration when sending scrap requests to node 2 and node 3?

Sincerely,

Vishal

Sorry for the typos earlier...

I am not sure whether it work, but did you try prometheus on node1 to listen only on your desired ip?

Thank you Charles, I did try this and in my particular case it didn't work. I had it listening on .176 but netstat showed .175 as the address being used to create tcp connection.

Hi Vishal,

Setting the source IP / interface to scrape from is not possible unfortunately.

Regards,

Julius
