Table 82. pool-statistics properties
Name Type Description
sample-time string Date and time, in the format year-month-day hour:minutes:seconds, when
the data sample was taken.
sample-time-numeric uint32 Unformatted sample-time value.
serial-number string The serial number of the pool.
pool string The name of the pool.
pages-alloc-per-minute uint32 The rate, in pages per minute, at which pages are allocated to volumes in the pool
because they need more space to store data.
pages-alloc-per-hour uint32 The rate, in pages per hour, at which pages are allocated to volumes in the pool because
they need more space to store data.
pages-dealloc-per-minute uint32 The rate, in pages per minute, at which pages are deallocated from volumes in the pool
because they no longer need the space to store data.
pages-dealloc-per-hour uint32 The rate, in pages per hour, at which pages are deallocated from volumes in the pool
because they no longer need the space to store data.
num-pages-unmap-per-minute uint32 The number of 4 MB pages that host systems have unmapped per minute, through use
of the SCSI UNMAP command, to free storage space as a result of deleting files or
formatting volumes on the host.
num-pages-unmap-per-hour uint32 The number of 4 MB pages that host systems have unmapped per hour, through use of
the SCSI UNMAP command, to free storage space as a result of deleting files or
formatting volumes on the host.
num-blocked-ssd-promotions-
per-minute
uint32 The rate, in pages per minute, at which pages cannot be moved to SSD. A consistent
non-zero rate may indicate the SSD tier is too small for the current workload.
num-blocked-ssd-promotions-
per-hour
uint32 The rate, in pages per hour, at which pages cannot be moved to SSD. A consistent non-
zero rate may indicate the SSD tier is too small for the current workload.
num-page-allocations uint64 The number of pages allocated to volumes in the pool because they need more space to
store data.
num-page-deallocations uint64 The number of pages deallocated from volumes in the pool because they no longer need
the space to store data.
num-page-unmaps uint64 The number of 4 MB pages that host systems have unmapped since statistics were last
reset.
