relabeling by metrics name

[antonios....@gmx.de]

Hi,


i try to rename the label "env" to "node_env" for the metric "machine_cpu_cores", but the regex does not work.

i added on my prometheus.yml the folowing lines:

relabel_configs:
...
    -   action: replace
        regex: .*machine_cpu_cores.*
        source_labels:
        - env
        target_label: node_env

The replacement only works if the regex-part is commented out, but then it replaces every metric.
I also tried regex: machine_cpu_cores and a lot of other regex-matches.


What am i doing wrong here?


Best,
Toni.

You want to use metric_relabel_configs. See https://www.robustperception.io/relabel_configs-vs-metric_relabel_configs/

Hi again,

i also tried out metric_relabel_config.

It only works without the regex line. This is strange somehow, since there are so many other examples.

Try:

- source_labels: [__name__, env]

  regex: 'machine_cpu_cores;(.*)'

  replacement: '${1}'

  target_label: node_env

This lets you have a condition on __name__ while capturing the value of env.
