Delete targets from prometheus

Hi all,

I have old instances on prometeheus that are deleted.

How I can delete the target in prometheus?

Also I have the same problem for a postgres added from grafana dashboard.

Many thanks all

Anyone can help me?
When I enter to htttp://percona/consul
the webpage is empty


Thanks for the info.

I want to delete from prometheus:
That endopoints down.

Also I have a PSQL BBDD monitored that removed, but created a new, and prometheus allways try to connect with it.
