Description: Sample histogram dashboard for HCICollector v0.7. 
It gathers a histogram metric - one of serveral - for all volumes and graphs its top quintile.
Screenshots shows another example which can be easily created by editing this sample dashboard.

Data is collected from SolidFire/Element v11/NetApp HCI storage cluster (v11 or higher) by https://github.com/scaleoutsean/hcicollector/blob/v0.7/sfcollector/solidfire_graphite_collector.py script and sent to GraphiteDB. 
See https://github.com/scaleoutsean/hcicollector/ (v0.7 or higher) for additional details.
