The default retention is set to 15d iirc, so once that ages out it wil disappear. You can also use promtool to manually delete out data if you really wish.

Now I deleted one of those instance(this is unreachable instance) from prometheus.yml file. When I am trying to query up == 0, still I am able to see this instance in the database. How to delete that particular instance in database? Any help? Thanks in advance.
