Another questions, please.. It is possible to modify retention to have more details on the dashboard ? i would like to replace the values in the /etc/carbon/storage-schema.conf from (values by defaults : #retentions = 1m:1h,2m:2h,4m:3h,12m:12h,24m:2d,96m:7d,192m:30d,3840m:1y) to this values : retentions = 20s:1d,1m:7d,5m:30d,1h:1y,2h:2y . But after services restarted the metrics on Dashboard doesn't change . Maybe i miss something ? Thank you again !
