Table A-10. Storage Device Panel Statistics (Continued)
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.
Table A-11 displays the interactive commands you can use with the storage device panel.
