Measure now for physical capacity

You can perform a measure now task, that is, a one-time measurement, for physical capacity of MTrees, Tenant Units, or Tenants, using the Measure Now dialog box.

1. Select all or multiple MTrees, a single MTree, a Tenant Unit, or a Tenant that you want to measure now.
2. Select Capacity > MTrees > Physical Capacity Measurement menu > Measure Now.
   In Classic View, select Capacity > Management > MTree tab > Physical Capacity Measurement menu > Measure Now
3. In the Measure Now dialog box, you can select Hide to keep the process going, but to not show the dialog box. You can monitor progress on the Jobs page.
   1. If the job submits successfully, a success message is displayed.
   2. If the job fails, the reason for failure is displayed when hovering over the "Failed" status.
   3. For entities associated with multiple systems (a single Tenant or multiple MTrees), if an error occurs, a table with the error on a per Data Domain system basis is displayed.
   4. After the job starts, it may take some time for it to complete.
      NOTE A physical capacity measurement takes roughly the same time as a cleaning cycle. This might be hours or, in extreme cases, days. Timing depends on the current workload of the system and how much data is in the MTree, Tenant Unit, or Tenant.

   It may take up to an hour for the physical capacity measurement data to show up on the MTree pages after the job is completed.
