Column
Description
WQLEN
World queue depth. This is the maximum number of ESX/ESXi VMkernel active commands that the
world is allowed to have. This is a per device maximum for the world. It is valid only if the
corresponding device is expanded to worlds.
ACTV
Number of commands in the ESX/ESXi VMkernel that are currently active. This statistic is applicable
only to worlds and devices.
QUED
Number of commands in the ESX/ESXi VMkernel that are currently queued. This statistic is applicable
only to worlds and devices.
%USD
Percentage of the queue depth used by ESX/ESXi VMkernel active commands. This statistic 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 statistic 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.
RESETS/s
Number of commands reset per second.
PAECMD/s
Number of PAE commands per second. This statistic is applicable only to paths.
PAECP/s
Number of PAE copies per second. This statistic is applicable only to paths.
SPLTCMD/s
Number of split commands per second. This statistic is applicable only to paths.
SPLTCP/s
Number of split copies per second. This statistic is applicable only to paths.
