Parameters

Parameter

Description

Value

pool_id=? ID of the storage pool whose performance statistics you need to collect.

To obtain the value, run "show storage_pool general".

pool_id_list=? ID list of storage pools whose performance statistics you need to collect.
  • To obtain the value, run "show storage_pool general".
  • Separate the IDs of storage pool with commas (,) or hyphens (-).
  • A maximum of 50 IDs can be queried.
