[Question]: Delete metrics for a specific target

[DigitalMarc]

Hi,
Prom version: 1.2.1

It seems that we can't use the delete API to remove a set of metrics such as:
{__name__=~".*",cluster="Test Cluster"}
The API reply with 400 Bad Request

full request made: curl -X DELETE -g 'http://localhost:9090/api/v1/series?match[]={__name__=~".*",cluster="Test Cluster"}'

How can we remove all the metrics that matches a specific field or, put differently, all metrics from a target?

Many thanks

That looks to be correct. Does that expression work in the expression browser?

[DigitalMarc]

Yes it does.

The space needs to be encoded as %20

[DigitalMarc]

Wonderful!

curl -X DELETE -g 'localhost:9090/prometheus/api/v1/series?match[]={instance="localhost:9100"}' | jq

{
  "status": "error",
  "errorType": "internal",
  "error": "not implemented"
}
