recently I'm trying to drop some metrics since prometheus usage is getting way too much than I expected.
metric_relabel_configs:
- source_labels: [__name__]
separator: ;
regex: (istio_requests_total)
replacement: $1
action: drop
But I tried this fairly straight forward metric_relabel_configs, "istio_requests_total" doesn't drop as expected. I know you may ask why I don't drop this in relabeling.
My very first goal is to drop all the metrics with destination_service = unknown associated with istio like :
- source_labels: [destination_service]
separator: ;
regex: ^unknown(.*)
replacement: $1
action: drop
This doens't work ,so I go back to a simple "metric" drop see if this can work. Anyways let me know if I made anything wrong and thank you all in advance !
