Thanks for answering,
Following what you wrote, I now have the following multiple times in my
config:
metric_relabel_configs:
- separator: ;
regex: id
replacement: $1
action: labeldrop
However, and after restarting the Prometheus stateful set, in my TSDB
status the ID label is still there, with the same cardinality as before, in
the table titled: "Top 10 label names with high memory usage"
Please advise.
