To ensure that replication isn't running the Delphix virtualization engine out of storage overall, go to
Manage >
Dashboard, where the total amounts of used and free storage are displayed.
For the details on the space consumed by the replicated namespace, similar to the detail shown in Resource > Capacity, the Delphix graphical user interface (GUI) doesn't have that, and I cannot find anything with that detail in the command-line interface (CLI) either.
Hope this helps...
