Thanks @Brian Candler Actually not possible fixing the data at source due to multiple variations in diff aws services and huge data modification. So looking to make it dynamically by capturing labels starting with "*tag_*".
As mentioned here https://github.com/prometheus/prometheus/blob/v2.45.4/model/relabel/relabel_test.go#L461-L482 can you please give me one example of config to achieve it dynamically for all labels starting with "*tag_*" It will be great help if that works for me. :) On Thursday, April 18, 2024 at 4:46:15 PM UTC+5:30 Brian Candler wrote: > You mean you're seeing tag_owner, tag_Owner, tag_OWNER from different > instances?
