How can I delete old Jobs from Prometheus?

Question

I have 2 jobs. One is new, the other is old.

I need to delete the old one, so that it gets removed from Grafana dashboard too.

Answer 1

Expanding on evgenyl's answer, the exact command would be something like:

curl -X POST -g 'http://localhost:9090/api/v1/admin/tsdb/delete_series?match[]={job="name_of_old_job"}'

Replace name_of_old_job with the name of the job you want deleted.

Reminder that you need to have started Prometheus with the --web.enable-admin-api flag
