Table 8‑3. Interactive Mode Single-Key Commands (Continued)
Key Description
p Switch to the CPU Power utilization panel.
m Switch to the memory resource utilization panel.
d Switch to the storage (disk) adapter resource utilization panel.
u Switch to storage (disk) device resource utilization screen.
v Switch to storage (disk) virtual machine resource utilization screen.
n Switch to the network resource utilization panel.
i Switch to the interrupt panel.
CPU Panel
The CPU panel displays server-wide statistics as well as statistics for the individual world, resource pool,
and virtual machine CPU utilization.
Resource pools, virtual machines that are running, or other worlds are at times called groups. For worlds
belonging to a virtual machine, statistics for the virtual machine that is running are displayed. All other
worlds are logically aggregated into the resource pools that contain them.
Table 8‑4. CPU Panel Statistics
Line Description
PCPU USED(%) A PCPU refers to a physical hardware execution context. It can be a physical CPU core if the
hyperthreading is unavailable or disabled, or a logical CPU (LCPU or SMT thread) if the hyperthreading is
enabled.
PCPU USED(%) displays the following percentages:
n
percentage of CPU usage per PCPU
n
percentage of CPU usage averaged over all PCPUs
CPU Usage (%USED) is the percentage of PCPU nominal frequency that was used since the last screen
update. It equals the total sum of %USED for Worlds that ran on this PCPU.
Note If a PCPU is running at frequency that is higher than its nominal (rated) frequency, then PCPU
USED(%) can be greater than 100%.
If a PCPU and its partner are busy when hyperthreading is enabled, each PCPU account for half of the
CPU usage.
PCPU UTIL(%) A PCPU refers to a physical hardware execution context. It can be a physical CPU core if the
hyperthreading is unavailable or disabled, or a logical CPU (LCPU or SMT thread) if the hyperthreading is
enabled.
PCPU UTIL(%) represents the percentage of real time that the PCPU was not idle (raw PCPU utilization).
It displays the percentage CPU utilization per PCPU, and the percentage CPU utilization averaged over all
PCPUs.
Note PCPU UTIL(%) might differ from PCPU USED(%) due to power management technologies or
hyperthreading.
ID Resource pool ID or virtual machine ID of the resource pool or virtual machine of the world that is running.
Alternatively, the world ID of the world that is running.
GID Resource pool ID of the resource pool or virtual machine of the world that is running.
