Description Eric Jones 2016-04-07 20:56:08 UTC 
Document URL: 
https://docs.openshift.com/enterprise/3.1/install_config/cluster_metrics.html#metrics-data-storage

Section Number and Name: 
Metrics Data Storage

Describe the issue: 
In reference to storage size, the documentation only says the following:

To use persistent storage with the metric components, ensure that a persistent volume of sufficient size is available. 

Suggestions for improvement: 
Provide a way to determine, based on your cluster configuration, what is "a persistent volume of sufficient size"
Comment 1 Eric Jones 2016-05-20 14:01:21 UTC 
The docs have been updated with a little more info about storage size, however, it still suggests that you should "ensure that the size requirements are sufficient for their setup and to monitor usage to ensure that the disk does not become full."

But still makes no reference as to how to determine what is sufficient size.

Is there a way to figure this out?
