POOL graphs in v1.10
POOL graphs became new default view when you open any storage.
New version has enhanced POOL data about storage front-end statistics for all storage types. There had been only POOL back-end statistics available since this release.
As POOL front-end data is a new feature then it does not have any data history and you will see empty graphs immediately after the upgrade.
POOL back-end data stay as it was include all its already captured history.
You can see it on our demo site
