Table 7‑7. Memory Panel Statistics (Continued)
Field Description
OVD_NDx (MB) VMM overhead memory allocated for a resource pool on NUMA node x. This statistic is
applicable on NUMA systems only.
TCHD_W (MB) Write working set estimate for resource pool.
CACHESZ (MB) Compression memory cache size.
CACHEUSD (MB) Used compression memory cache.
ZIP/s (MB/s) Compressed memory per second.
UNZIP/s (MB/s) Decompressed memory per second.
Table 7‑8. Memory Panel Interactive Commands
Command Description
M Sort resource pools or virtual machines by MEMSZ column. This is the default sort order.
B Sort resource pools or virtual machines by Group Memctl column.
N Sort resource pools or virtual machines by GID column.
V Display virtual machine instances only.
L Changes the displayed length of the NAME column.
Storage Adapter Panel
Statistics in the Storage Adapter panel are aggregated per storage adapter by default. Statistics can also be
viewed per storage path.
Table 7‑9. Storage Adapter Panel Statistics
Column Description
ADAPTR Name of the storage adapter.
PATH Storage path name. This name is only visible if the corresponding adapter is expanded. See
interactive command e in Table 7-10.
NPTH Number of paths.
AQLEN Current queue depth of the storage adapter.
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.
RESV/s Number of SCSI reservations per second.
CONS/s Number of SCSI reservation conflicts per second.
DAVG/cmd Average device latency per command, in milliseconds.
KAVG/cmd Average ESXi VMkernel latency per command, in milliseconds.
GAVG/cmd Average virtual machine 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.
