It's pretty obvious that lots of print jobs are running on your cups server. In my case there are more than one cups servers running behind a load balancer. So tracking their active jobs will work for you to check if they spread across on the servers smoothly.
Schema definitions for Whisper files in the storage-schemas.conf are expressed:
pattern = ^print_stats.*
retentions = 1m:7d,30m:2y

# ./feed_graphite.sh >/dev/null 2>&1 &
