How to remove old system from site from Harvest/Grafana/Graphite? Simply deleting it does not work, because the pages are no longer served. How can it be done otherwise?
Also check this section in the faq - "I’m running out of space, how can I manually clean up ?" you can safely remove any file or directory in the /opt/graphite/storage/whisper/directory. Anything you remove here will then disappear from grafana itself, there is no other database or registry. https://nabox.org/faq/
