Modify the configuration files:
  cat /opt/graphite/conf/storage-schemas.conf
<code>[carbon]
pattern = ^carbon\.
retentions = 60:90d

[default]
priority = 110
pattern = .*
retentions = 15s:7d,1m:21d,15m:5y

RRD_DIR = '/opt/graphite/storage/rrd'
DATA_DIRS = [WHISPER_DIR, RRD_DIR] # Default: set from the above variables
LOG_DIR = '/opt/graphite/storage/log/webapp'
INDEX_FILE = '/opt/graphite/storage/index'  # Search index file
