Hi
 
We are using NaBox for our implementation of Harvest / Grafana/ Graphite. It's really a wonderful tool and easy to use and implement. 
 
Quick question:
 
How do I remove old systems and groups from Harvest / Grafana / Graphite?
 
I see the data here via the shell:
 
/opt/graphite/storage/whisper/netapp/perf/sitename
/opt/graphite/storage/whisper/netapp/poller/perf/sitename
 
Simply deleting the directories above though causes Grafana to stop serving pages. Is there another method?
 
Thank you,
 
Adam P
