Looks OK to me, if your instance labels are of the form name:port. It should take effect pretty much instantaneously.
You could add -v to the the curl command line, to see the response code (204 / 400 etc) Of course, the metrics will reappear if you are still scraping them, which might be because: - you've changed prometheus.yml without sending a HUP signal to reload the config - you've changed prometheus.yml, you've sent a HUP signal, but the new config has a syntax error (in which case prometheus will keep running with the old config) Check with: journalctl -eu prometheus On Sunday, 11 December 2022 at 17:10:43 UTC [email protected] wrote: > curl -X POST -g ' > http://localhost:9090/api/v1/admin/tsdb/delete_series?match[]={instance= > "instance:port"}' > > Is the above query correct?
