Replace instance label with regex
I'm trying to replace the instance label of a given job. I understand that I can do this with the
relabel_config. But I struggle with the regex and regex replace stuff.
My targets have an obscure target url like
test1.mysite.de. There are reasons why I can't change these, so I need to do some relabeling.
This is my current config:
relabel_configs: - source_labels: [__address__] target_label: instance regex: ^test.* replacement: server
But this relabels the url to
server. What's my mistake?
