I have install prometheus (v2.1.0 from Ubuntu 18.04's apt repository), and I have played around with adding hosts & metrics and all that for about a week. I want to “start fresh” and delete all existing stored data & metrics. How can I do this?

Mostly i would suggest to look for howtos that regards to backup this peace because then you know how to get rid off tze data. Thats how i do on generic unknown software – djdomi Oct 28 '21 at 17:06

Prometheus stores its TSDB in /var/lib/prometheus in most default packages.

It will initialize it on startup if it doesn't exist so simply clearing its content is enough.

If you've played around with remote_write however, you'll need to clear the long-term storage solution which will vary depending on which storage solution it is.

If you want to reset its configuration, delete /etc/prometheus and reinstall the package.
