Re: [prometheus-developers] Re: auto discover of targets in Prometheus

[Gajendra Ambi]

Hi,
I too just discovered that it does not do dynamic discovery. I have to tell 
prometheus to see it by using file based discovery in prometheus. This is 
very unfortunate where we have 100s of nodes and growing and each group of 
devs who own them get to add them when they want. Currently it seems We 
have to do it manually. Thanks for the quick info.

[prometheus-developers] Re: auto discover of targets in Prometheus

[Gajendra Ambi]

Everyone gives the same link 
https://prometheus.io/docs/prometheus/latest/configuration/configuration when 
asked about auto discovery of physical nodes but the entire page has only 2 
occurences of the word auto-discovery. 
We have 700+ physical servers and Prometheus is running on k8s (targets are 
not part of k8s). Can someone please point to a blog or the actual part of 
the documentation which has auto discovery of physical nodes, not the same 
link please. I could not find anything there. It says, you can do it using 
1 of the auto discovery methods but the link does not have a single method 
of auto discovery listed there.
