Using Harvest has been invaluable and helped us deep dive on a number of problems.
Monitoring 12- 14 clusters I have an issue with volume numbers.
Harvest traps every volume including temporoary volumes cloned from backups by CommVault.
The problem is that there are so many volumes (even in one SVM) the dropdown volume list truncates around 800 volumes.
I there a way to filter out volumes with a prefix so they are not recorded in by Harvest?
There are specific prefixes.

Harvest does not have a feature to exclude collection of specific instances, but you can configure the Graphite server to drop them by using the blacklist feature. Details on how to set this up are in the Harvest 1.3 Administration guide on pg 24 " Use a blacklist to prevent visibility of temporary volumes [optional] ". If you have stale metrics you might also like to delete them as a one time action and setup in cron using details on pg 25 in "Purging inactive metrics from Graphite [optional]"
Hope this helps!

Have updated the blacklist and removed the stagnant commvault files adn created the cron.
Grafana directory structure almost halved in size and drilldown to volume level is much faster.
I've setup a blacklist however it does not seem to ignore volumes.
What have I got wrong?
