Table 7‑6. CPU Power Panel Statistics (Continued)
Line Description
%Px Percentage of time the physical CPU spent in P-State 'x'. On systems with Processor Clocking
Control, P-states are not directly visible to ESXi. Theesxtop shows the percentage of time spent
at full speed under the heading 'P0' and the percentage of time spent at any lower speed under
'P1'.
%Tx Percentage of time the physical CPU spent in T-State 'x'.
Memory Panel
The Memory panel displays server-wide and group memory utilization statistics. As on the CPU panel,
groups correspond to resource pools, running virtual machines, or other worlds that are consuming
memory.
The rst line, found at the top of the Memory panel displays the current time, time since last reboot, number
of currently running worlds, and memory overcommitment averages. The memory overcommitment
averages over the past one, ve, and fteen minutes appear. Memory overcommitment of 1.00 means a
memory overcommitment of 100 percent.
Table 7‑7. Memory Panel Statistics
Field Description
PMEM (MB) Displays the machine memory statistics for the server. All numbers are in megabytes.
total
Total amount of the machine memory in the server.
vmk
Amount of the machine memory being used by the ESXi
VMkernel.
other
Amount of the machine memory being used by everything
other than the ESXi VMkernel.
free
Amount of the machine memory that is free.
VMKMEM (MB) Displays the machine memory statistics for the ESXi VMkernel. All numbers are in
megabytes.
managed
Total amount of the machine memory managed by the ESXi
VMkernel.
min free
Minimum amount of the machine memory that the ESXi
VMkernel aims to keep free.
rsvd
Total amount of the machine memory currently reserved by
resource pools.
ursvd
Total amount of the machine memory currently unreserved.
state
Current machine memory availability state. Possible values are
high, soft, hard and low. High means that the machine memory
is not under any pressure and low means that it is.
NUMA (MB) Displays the ESXi NUMA statistics. This line appears only if the ESXi host is running on a
NUMA server. All numbers are in megabytes.
For each NUMA node in the server, two statistics are displayed:
n
The total amount of machine memory in the NUMA node that is managed by ESXi.
n
The amount of machine memory in the node that is currently free (in parentheses).
Shared memory for the ESXi host might be larger than the total amount of memory if
memory is over-commied.
