Table 7‑11. Storage Device Panel Statistics (Continued)
Column Description
WORLD World ID. This ID is visible only if the corresponding device is expanded to worlds. See the
interactive command e in Table 7-12. The world statistics are per world per device.
PARTITION Partition ID. This ID is visible only if the corresponding device is expanded to partitions. See
interactive command t in Table 7-12.
NPH Number of paths.
NWD Number of worlds.
NPN Number of partitions.
SHARES Number of shares. This statistic is applicable only to worlds.
BLKSZ Block size in bytes.
NUMBLKS Number of blocks of the device.
DQLEN Current device queue depth of the storage device.
WQLEN World queue depth. This is the maximum number of 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 ESXi VMkernel that are currently active. This statistic applies to only
worlds and devices.
QUED Number of commands in the ESXi VMkernel that are currently queued. This statistic applies to only
worlds and devices.
%USD Percentage of the queue depth used by ESXi VMkernel active commands. This statistic applies to
only worlds and devices.
LOAD Ratio of ESXi VMkernel active commands plus ESXi VMkernel queued commands to queue depth.
This statistic applies to only 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 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 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 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 applies to only paths.
