Table A-12. Virtual Machine Storage Panel Statistics (Continued)
Column Description
BLKSZ Block size in bytes. It is valid only if the corresponding world is expanded to devices.
NUMBLKS Number of blocks of the device. It is valid only if the corresponding world is expanded to devices.
DQLEN Storage device queue depth. This is the maximum number of ESX/ESXi VMkernel active commands
that the device is configured to support. The displayed number is valid only if the corresponding world
is expanded to devices.
WQLEN World queue depth. This column displays the maximum number of ESX/ESXi VMkernel active
commands that the world is allowed to have. The number is valid only if the corresponding world is
expanded to devices. This is a per device maximum for the world.
ACTV Number of commands in the ESX/ESXi VMkernel that are currently active. This number is applicable
only to worlds and devices.
QUED Number of commands in the ESX/ESXi VMkernel that are currently queued. This number is applicable
only to worlds and devices.
%USD Percentage of queue depth used by ESX/ESXi VMkernel active commands. This number is applicable
only to worlds and devices.
LOAD Ratio of ESX/ESXi VMkernel active commands plus ESX/ESXi VMkernel queued commands to queue
depth. This number is applicable only to worlds and devices.
CMDS/s Number of commands issued per second.
READS/s Number of read commands issued per second.
WRITES/s Number of write commands issued per second.
MBREAD/s Megabytes read per second.
MBWRTN/s Megabytes written per second.
DAVG/cmd Average device latency per command in milliseconds.
KAVG/cmd Average ESX/ESXi VMkernel latency per command in milliseconds.
GAVG/cmd Average guest operating system latency per command in milliseconds.
QAVG/cmd Average queue latency per command in milliseconds.
DAVG/rd Average device read latency per read operation in milliseconds.
KAVG/rd Average ESX/ESXi VMkernel read latency per read operation in milliseconds.
GAVG/rd Average guest operating system read latency per read operation in milliseconds.
QAVG/rd Average queue read latency per read operation in milliseconds.
DAVG/wr Average device write latency per write operation in milliseconds.
KAVG/wr Average ESX/ESXi VMkernel write latency per write operation in milliseconds.
GAVG/wr Average guest operating system write latency per write operation in milliseconds.
QAVG/wr Average queue write latency per write operation in milliseconds.
ABRTS/s Number of commands aborted per second in milliseconds.
RESETS/s Number of commands reset per second in milliseconds.
