Table A-11. Storage Device Panel Interactive Commands
Command Description
e
Expand or roll up storage world statistics. This command allows you to view storage resource utilization
statistics separated by individual worlds belonging to an expanded storage device. You are prompted
for the device name. The statistics are per world per device. This is not applicable to NFS.
p
Expand or roll up storage path statistics. This command allows you to view storage resource utilization
statistics separated by individual paths belonging to an expanded storage device. You are prompted for
the device name. This is not applicable to NFS.
t
Expand or roll up storage partition statistics. This command allows you to view storage resource
utilization statistics separated by individual partitions belonging to an expanded storage device. You
are prompted for the device name. This is not applicable to NFS.
r
Sort by READS/s column.
w
Sort by WRITES/s column.
R
Sort by MBREAD/s column.
T
Sort by MBWRTN column.
N
Sort first by DEVICE column, then by PATH, WORLD, and PARTITION column. This is the default sort
order.
L
Changes the displayed length of the DEVICE column.
NFS Statistics
In ESX 4.0 Update 2, esxtop can report NFS statistics.
n
NFS datastores are displayed by prepending {NFS} to the datastore name.
n
For disk devices that are not NFS, you can expand or roll up the device in the display. For NFS disk devices,
expand or roll up does not exist.
n
NFS statistics are included in display sort, such as the r, w, and N commands.
n
Statistics that are not available for NFS will be shown as -.
Virtual Machine Storage Panel
This panel displays virtual machine-centric storage statistics.
By default, statistics are aggregated on a per-resource-pool basis. One virtual machine has one corresponding
resource pool, so the panel really displays statistics on a per-virtual-machine basis. You can also view statistics
on a per-world, or a per-world-per-device basis.
Table A-12. Virtual Machine Storage Panel Statistics
Column Description
ID Resource pool ID of the running world’s resource pool or the world ID of the running world.
GID Resource pool ID of running world’s resource pool.
NAME Name of running world’s resource pool or name of the running world.
Device Storage device name. This name is visible only if corresponding world is expanded to devices. See the
interactive command I below.
NWD Number of worlds.
NDV The number of devices. This number is valid only if the corresponding resource pool is expanded to
worlds
SHARES Number of shares. This statistic is only applicable to worlds. It is valid only if the corresponding resource
pool is expanded to worlds
