labeldrop

[Steve]

Hi

labeldrop is straightforward when you know the label to drop.

What if the labels are not known or the list is too long?

For instance. 

After relabel_configs, I have the following labels in my timeseries:

- job

- instance

- pod_name

- namespace

What should be the metric_relabel_configs to drop all other labels?

Does regex support negative matches?

Thank you

-Steve

You can use labelkeep.

- regex: "(job|instance|pod_name|namespace)"
action: labelkeep

Note, as per doc:
Care must be taken with labeldrop and labelkeep to ensure that metrics
are still uniquely labeled once the labels are removed.
